canon lcd panel doesn't shut off brands

"Just like Canon"s Professional series line of camera"s the EOS 90D does not have an eyepiece sensor to turn off the LCD screen and requires the info button to be pressed in order to turn off the LCD screen while shooting photos through the viewfinder."

My recollection is that the shutoff "feature" wasn"t there because it was thought to be a convenience for the user. Like the rubber eyepiece cover that attaches to the neck strap, it was meant to keep light from the screen from leaking in through the eyepiece and biasing the metering. Perhaps the newer, better cameras are considered to be sufficiently insulated from spurious light that the shutoff is unnecessary. Note that if the screen serves as a touchscreen, you might specifically not want the shutoff.

Went out this AM with my new R5 + grip (about 2 weeks past return period) and after turning on the back LCD screen got a block of vertical lines in it then slowly faded to darkness. The EVF seemed to still be working but then promptly stopped as well. The top LCD remained on the whole time and had a full battery indicator. If I turned it off it would sometimes turn off but after doing this process several times it occasionally would NOT turn off and the only way to power down was removing the battery tray from the grip. I tried putting a single battery in the camera without grip but no change. The battery indicator on top LCD continued to indicate full charge throughout. The back LCD was never responsive to touch input so I could not review settings or anything else.

I don"t recall running the batteries (which are stock Canon LP-E6NH) down or even near down on my last shoot which was just last weekend. The camera has been in my bag since that time in a climate controlled space. No exposure to moisture or impact or anything else. I"m hoping that the batteries have run down and I just didn"t notice so I"m charging it now. I have generally kept spare batteries on hand with previous camera setups just haven"t gotten around to buying a few extras because even after a heavy 4 hours of shooting 3k+ photos, I never go below half charge in a gripped 2-battery setup. But, if that"s the issue I will go back to my usual and previous practice, which is generally a good move. The cost of the batteries just lost me a nice morning out shooting. Fortunately the green light is on the grip and lightning charge bolt is on the top LCD so the camera at least seems to know it"s being charged. I just can"t figure out the top LCD saying full charge the whole time. Doesn"t make sense.

My R5 surely does diminish battery life between uses to a degree my previously SONY A9I/II or Canon 5D3 never did, which is disappointing. I know there are lots of settings to adjust to improve battery life when the camera is on, but I"m not aware of much I can do (except remove the batteries... which would hopefully work!!!) to stop any battery loss while the camera is off... and it was OFF when I went to use it this AM. I had not inadvertently left it on. I don"t recall if it the R5 has an auto-Off feature, but certainly good to have. I"m also curious about the always on nature of the top LCD. Probably a slow power draw, but certainly a power draw. I don"t find myself using it much for the work I"m doing now so might look to see if it can be turned off all the time. I certainly don"t need an LCD displaying information for me while my camera is off as there is no utility in that for me at all.

It doesn"t describe how to disassemble the rear panel but it shouldn"t be too hard. Take great care of any springs so you know how to refit them, make lots of notes about where screws come from, and keep them separate as there may be several sizes. You may find a loose connector, or maybe a ribbon bonded directly to the LCD, in which case a little bit of packing inserted behind it to increase the pressure may be sufficient to fix it.

The Canon PowerShot A720 IS is a compact, lightweight digital camera used primarily for quick point and shoot photography with several photo features and options, such as video recording, red eye reduction, a 2.5 inch LCD screen, 8.0 megapixels and a flash memory slot.

Note: This troubleshooting guide covers general problems with the Canon PowerShot A720 IS so you can identify what is wrong before referring to the repair guide to fix it.

The first thing to check if your digital camera won"t turn on is to press the on/off power button. The power button is located on the top surface of the camera and is the small button on left side of the mode dial. You should feel a slight difference in heights between the button and top surface of the camera when the button is pressed.

You may want to check your 2 AA batteries if your digital camera won"t turn on or turns off on its own. They may be the wrong size or inserted incorrectly if the Canon PowerShot A720 IS won’t turn on. Make sure that they are size AA and that you have the positive terminal end of the battery facing out in the front slot and the negative terminal end facing out in the back slot.

Try replacing your batteries with new ones or with batteries that are fully charged for those that are rechargeable. Low battery power might be the reason why the Canon PowerShot A720 IS turns off on its own.

If the Canon PowerShot A720 IS comes into contact with any type of liquid, you may have to the disassemble the camera into a few major components to let the parts dry in a safe and dry area or carefully place the major components in a bag of dry rice. When the components are completely dry, reassemble and try again.

If the digital camera still doesn"t power on, consider replacing the batteries or the motherboard. The motherboard probably blew a circuit when the liquid came into contact with the motherboard.

If LCD screen on the Canon PowerShot A720 IS displays a blank screen while the camera is powered on, you may want to press the Display button. The function of the Display button is to turn on and off the LCD screen. The button is located next to the LCD screen on the back of the camera and is labeled as DISP. Sometimes the display on the LCD screen shuts off when the camera enters its power saving mode or if the Display button was accidentally pressed.

If the LCD screen is still blank, then it may be due to low battery power. Replace both of the AA batteries with new or fully charged ones, turn the camera on, and press the Display Button.

After you have tried the previous troubleshooting steps and the problem persists, you may want consider the LCD screen repair guide to check for faulty internal wire connections that are connected to the power supply, LCD screen, and the motherboard. If you have replaced the LCD screen and the wires connections are intact after examination, then you may want to replace the motherboard.

When the camera repeatedly becomes unresponsive to user input, wait a few minutes to allow the camera to finish any processes that it may have started. If a significant amount of time passes and the camera is still unresponsive, recycle power by using the on/off button and remove and reload the batteries into the camera. When the Canon PowerShot A720 IS is back on, check to see if the frozen image has been removed.

If the frozen image on the LCD screen is the most recent picture shot, toggle the camera and video recording mode switch up and down. The mode switch is located in the top left corner of the back panel of the camera.

After you have tried the previous troubleshooting steps and the problem persists, you may want consider the LCD screen repair guide to check for faulty internal wire connections that are connected to the power supply, LCD screen, and the motherboard. If you have replaced the LCD screen and the wires connections are intact after examination, then you may want to replace the motherboard.

The lens usually causes flickering LCD screens when the lens focuses on light from a fluorescent light source. Simply turn away or move from the light source or reduce the lighting in the area stop the screen from flickering.

You may have one or many dead pixels if you notice an extremely small black square or many of them scattered across the LCD screen. If you see a large black blot, then your LCD screen is cracked and the liquid portion had spilled onto the glass screen. If either situation occurred, you have no other option than to replace the camera’s LCD screen.

If the Canon PowerShot A720 IS has a dark or faint screen but the digital camera is still operational, then the backlight may have burned out. Unfortunately, there are no LCD screen bright adjustment settings on the settings menu. You may want to verify this by taking the camera apart and replace the LCD screen. If the problem persists, there may be more significant damage to the Canon PowerShot A720 IS associated with the motherboard. Use the motherboard replacement guide to replace the motherboard.

Should a constant and straight bright red or purple line appear either across or vertically, refer to the LCD screen replacement guide to check the wires connections between the motherboard and the LCD and/or replace the LCD screen.

Go to the back panel of the Canon PowerShot A720 IS and press the small button labeled MENU. Use the circular directional pad to navigate through the menu screen. Select settings tab and make sure that the camera is not on mute. If mute is on, turn it off and then on again. Power the digital camera down and restart. If you do not hear the chime or the chime is distorted, then the internal speaker may have some problems.

The battery compartment cover may not be properly shut and locked while operating the camera. Just close the cover securely and restart the camera, and the lens should retract.

The lens housing unit could have some debris in it. You can clean the lens housing unit by first powering the camera off and pressing the plastic lens ring button located on the lower left side of the lens when the camera is facing you. Then carefully unscrew the ring to remove it. Next, carefully wipe the lens housing unit with a dry cloth when the lens is fully extended. Otherwise, the lens could be damaged. Then turn the camera back on and off to see if the lens will retract. If the lens housing unit still does not retract, follow the lens disassembly guide to take apart the lens and carefully wipe again before reassemble.

Initially, use the tweezers to free the shutter button if it is stuck. Carefully apply the tip of one end of the tweezers in the space between the button and the panel and try to get just underneath the button to pop it back in place. Do not force or jam the tweezer if it does not fit in the space. If the button is unable to pop back into its position, replace the spring contact that is associated with that button with the shutter button replacement guide.

When buttons are loose, they may have somehow been disconnected from the their contact spring. Use the shutter button replacement guide to reattach or replace the spring and connect it to the shutter button.

The subject may be out of focal range, hard to focus on, or the camera may have the wrong focal settings if the images appear blurry and out of focus. You may want refer to the Canon PowerShot A720 IS user manual to learn about the different settings.

If you still receive blurry and out of focus images, make sure that you are using the correct zoom setting and allowing the camera to focus on the subject before taking a picture. To focus, press the shutter button only half way down. When you hear the camera finish focusing, you can then completely press down on the shutter button to take the picture.

If the above does not work, you may want to restore the camera back to factory settings and restart the camera and try taking a picture. Again, if the same problem occurs, you may want to check the shutter button and follow the unresponsive shutter button portion of the troubleshooting page. If it is not the button, you may want to replace the check the wires and/or replace the motherboard.

Camera failures can happen anytime. Even the high-end Nikon, Sony or Canon cameras are not devoid of malfunctions. Sometimes it is a digital camera sensor problem, pictures showing black screen, or just your camera falling into water leaving you in a fix!

Here we have listed 12 common camera problems and their solutions. You can apply the troubleshooting methods in various types of digital cameras, DSLRs, SLRs, etc. The solutions cover all popular brands of Nikon, Fuji, Sony, Canon, Panasonic, Kodak, Olympus and other.

Once everything is in place, press the power button to turn on the camera. If still, your camera doesn"t turn on, the battery could be faulty and need replacement.

Download Stellar Photo Recovery software to retrieve lost or deleted photos and videos from SD card. The software supports all types of memory cards used in Nikon, Canon, Sony, Fuji, etc.

The error message, "Error. Press shutter release button again" on digital camera LCD is often a hardware issue. The gear motor of the Shutter either gets tight, damaged or contaminated with dust. Lubricating the gear motor can help. If your digital camera is under warrantee, turn to the dealer for replacement or repair. Don"t open it yourself.

Use back-button focus technique in which the shutter release takes the shot while a button (AF-ON or AE AF lock) on the back locks the focus. Hold the back button continuously while taking a shot. And as soon as you take off your finger from the back button, the focus gets locked.

The lens error messages can freeze your camera. Even turning it off and on won"t help. Usually, a lens error occur when the lens has dirt or it is not fitted properly on the camera.

Battery errors such as "cannot communicate with battery" or incompatible battery error" on Canon, Sony or Nikon DSLRs are reported by many users. It usually appears when your batteries are not connected properly; there is dust in the battery terminals/ compartment; or the battery is damaged.

Like the Rebel XS before it, the Canon T3 relies on its modestly sized 2.7-inch color LCD screen for all user interaction. This makes for a clear, highly visible user interface, but probably does contribute to slightly shorter battery life, since the LCD has to be fired up any time you want to change anything beyond the most basic settings. (Exposure mode, aperture, shutter speed, exposure compensation, and exposure lock are the only things that can be configured without using the rear-panel display). One feature we miss from Canon"s mode advanced models that"s missing from the XS is the infrared proximity sensor that turns off the LCD screen when you hold the camera up to your eye. It would not only conserve battery life, but would also reduces glare from the LCD when using the optical viewfinder. The Rebel XS instead disables the LCD when the shutter button is half-depressed. (You can optionally leave it on until the DISP or Set button is pressed.)

Overall, the control layout places a few main controls (Power switch, Shutter button, Main dial, Mode dial, and Flash button) on the right side of the Canon T3"s top panel, with most of the other controls on the back of the camera. Let"s take a closer look at some of the user-interface elements:

There are four Screen color options on the Status display, adjustable in the first Settings menu, under Screen Color. The color choices--and indeed, the information layout--on the Canon T3 are pretty radically different from those on the XS. I found myself preferring the default color scheme (top left in the group of shots above) in the daytime, thanks to its strong contrast. Color scheme 4 (bottom right) was similarly useful for shooting at night, reducing the contrast just slightly so as not to tire my eyes.

Whatever exposure parameter is currently being controlled by the Canon T3"s Main Dial is highlighted with arrows in the corners of its box, to indicate that it can be changed by rotating the dial. Here, we"re adjusting the shutter speed, marked by the outlined box. Note the arrows. (They"re pretty subtle; we would have liked to see them a bit more prominent.)

The rear-panel display on the Canon T3 is also used for Canon"s Quick Control menu system, first introduced in the Rebel T1i. As with the later T2i model, though, nstead of using the SET button to enter the Quick Control menu, there"s a Quick Control button dedicated to this purpose. Regardless of whether the LCD display was active or disabled, pressing the Quick Control button on the Canon T3 while in capture mode takes you to the Quick Control menu system, where you can adjust various settings shown on the rear-panel display. You navigate between the various setting options with the arrow keys, and the chosen setting will be highlighted as shown above. Once a setting has been selected, you can change it either by rotating the Canon T3"s Main Dial, or by pressing the SET button, and then using the arrow keys to choose from the available options. The Quick Control menu is dismissed with a second press of the Quick Control button.

Pressing any of the arrow keys to the right of the Canon T3"s LCD screen (if available in the current exposure mode), or the Set button while making changes in the Quick Menu, immediately brings up a screen for the exposure parameter associated with that button. Once the option screen is displayed, you can use either the arrow keys or the Main Dial to scroll the cursor highlight through the options presented. You can continue to press the same arrow-key button, or turn the Main Dial in the same direction, and the highlight will scroll through all the options, wrapping around when it gets to the end of the list. When you"ve made the choice you want, pressing Canon T3"s Set button confirms it and returns you to the main shooting display or Quick Menu, as appropriate.

Like the Rebel XS, the Canon T3 shows each image as it"s captured, though you can turn off this function through the Record menu. The display mode in Record Review defaults to the same as was last used in Playback mode, or you can hit the DISP button to cycle to a different mode. Likewise, in Playback mode, you can cycle between the available display options by pressing the Canon T3"s DISP button repeatedly. (Display mode selection is persistent across both record and playback modes, no matter which mode you make the selection in.) You can also select between the normal luminance-based histogram and the RGB histogram option via a Playback-mode menu item. The screenshots below show the various displays and options available.

This is the default display in playback mode. The folder and file number is displayed upper right, and the shutter speed, aperture, and exposure compensation (if applicable) in the upper left, while the file sequence number and quality are shown below left.

The Canon T3"s third playback display option shows both RGB and luminance histograms side by side, along with an intermediate level of exposure information. If there are any blown highlights, they"ll blink in this mode.

The final playback display option is image with no overlay. Since the T3"s screen doesn"t match the aspect ratio of its images, this still leaves a bar at the top of the image with the shutter speed, aperture, exposure compensation (if applicable), folder numbre, and file number.

If you press the Zoom Out button while viewing a single image on the LCD screen, it"ll take you first to a 4-image thumbnail display, and then to a 9-image one, if you press it once again. The arrow keys let you navigate among the thumbnail images. The text above the thumbnails displays the same basic exposure info for the currently-selected image as does the default single-image display. Pressing the DISP button in this mode overlays the image size/quality and file number for the currently selected image, as in normal playback mode.

By turning the Main dial on the Canon T3 in Playback mode, you can "jump" through images in a variety of ways. An option on the Playback menu sets options of jumping through images 1, 10, or 100 images at a time, between shots captured on different dates or stored in different folders, between groups of movies, or groups of still shots. You can also jump between images by rating, either viewing only rated images, only unrated images, or only those with a specific rating. The jump menu setting only applies when you"re in single-image playback mode. In thumbnail display mode, the Main Dial always jumps ahead one screen of thumbnails at a time, regardless of the menu setting for the Jump option.

OK, I don"t have the 6D but I am assuming that there is a setting in the menus for "review time", which tells the camera how long you want it to display an image after you take a shot. Personally, I always set any camera to "off" in that regard so that it doesn"t light up the LCD at all unless I tell it to. It may have an option to leave it on until cancelled (with the shutter button for example) and that could be your issue. Check the review time and either set it to "off" or "x seconds" to your preference.

You may experience problems with your Canon camera from time to time that don"t result in any error messages or other easy-to-follow clues as to the problem. Troubleshooting such problems can be a little tricky. Use these tips to give yourself a better chance of success with your Canon camera troubleshooting techniques.

A few issues can cause this problem in a Canon camera. First, make sure you charge the battery and insert it properly. Even if the battery was inserted in a charger, it"s possible the battery wasn"t inserted properly. Or, possibly, the charger was not plugged into an outlet properly, meaning the battery did not charge.

With this problem, you may have inadvertently opened the battery compartment cover while operating the camera. In this case, close the battery compartment cover securely. Then turn the camera on and off, and the lens should retract.

Some Canon PowerShot cameras have a DISP button, which may turn the LCD on and off. Press the DISP button to turn on the LCD. This is common when the Canon PowerShot camera has an electronic viewfinder option for framing photos, along with the LCD screen for framing photos. The live screen may be active with the electronic viewfinder, so pressing the DISP button can switch the live screen back to the LCD screen.

If you hold the camera near a fluorescent light, the LCD screen image may flicker. Move the camera away from the fluorescent light. The LCD also may appear to flicker when viewing a scene while shooting in minimal light. But if the LCD screen seems to flicker in all types of shooting situations, you may need a repair.

White dots are most likely caused by the light from the flash reflecting off dust or other particles in the air. Turn off the flash or wait until the air clears to shoot the photo.

Some Canon point and shoot cameras don"t exactly match the LCD image and the actual photo image. LCDs might only display 95 percent of the image shot, for example. This difference is exaggerated when the subject is close to the lens. Look through the specification list for your Canon PowerShot camera to see if they list a percentage of scene coverage.

Figuring out how to show photos on a TV screen can be tricky. Press the Menubutton on the camera, select the Settingstab, and match the video system settings in the camera with the video system the TV uses. Some PowerShot cameras cannot display photos on a TV screen because the camera doesn"t have an HDMI output capability or an HDMI output port.

The printer suddenly turns off without warning. A print, copy, scan, or fax job fails because power might be low or the printer is off. The printer does not respond to any job when it is turned off. When the printer is connected to an outlet that supplying low power problem, the printer might turn off repeatedly.

Your HP printer is designed to reduce power consumption when the printer is not active. Auto Power Off or Schedule On and Off enables the printer to turn off after two hours of inactivity. When you are ready to use your printer again, press the Power button to turn the printer back on.

Open the Setup menu, and then click Preferences. Click Schedule Off, Auto Power Off or Auto-off, depending on your printer model, and then change any settings, if necessary.

Having too many other electronic devices connected to your printer might cause your printer to lose power and turn off. Make sure the USB cable runs directly from the computer to the printer.

If the indicator light on the power module is off, or if the power module does not have an indicator light and you have tried all of the preceding solutions, replace the power module.

If the indicator light on the printer is off or if there is no indicator light, and you have tried all the preceding solutions, continue to the next step to Service the printer.

Install an HP chip to a replacement cartridge. This requires some fine motor skills and good tools. You’ll also possibly need to turn off toner level monitoring on the printer.

Canon printers have thermal printheads. The ink actually cools the print heads down, and if you run empty cartridges the print heads can overheat and get damaged.

So, if you replace and remove the four Canon cartridges, and, on the fifth attempt, install a newly refilled cartridge, the printer should accept the cartridge, and ink levels should read as full.

I have read through all 919 pages of the Canon EOS R5 user manual so I could collate important information you may or may not know about the camera. If you are thinking about buying the camera with video as the primary purpose, then it may well help to have a read below.

Now, this is just information from the user manual and the reality is that real-world shooting conditions hardly ever mimic ideal shooting conditions that are listed in manuals. I haven’t shot with or even touched an EOS R5. This is not my thoughts or opinions on the camera, its just information listed officially by Canon that you may need to know.

Even with [Time code] set to [Off], external recording devices may add time codes to movies, depending on their specifications. For details on device specifications relevant to adding time code to HDMI input, check with the device manufacturer.

Just a note: If you set the power switch to while an image is being recorded to the card, [Saving…] will be displayed and the power will turn off after the recording finishes. This is a safety feature to make sure that a recording isn’t lost if you accidentally power the camera off.

With Canon Log, movies may be affected by horizontal banding, depending on the subject or shooting conditions. Record a few test movies and check the results in advance. In particular, noise may become more noticeable if you enhance the contrast when color-grading your movies.

Histograms of images captured with [Canon Log] set to [On] are not based on images as converted for View Assist display. Image areas shown in gray in the histogram roughly indicate signal values that are not used.

You can use a View Assistfeature when shooting in Canon Log. View Assist is basically just a LUT. Setting this feature to [On] does not affect movies recorded to the card, they are still recorded as Canon Log. Similarly, the HDMI video output will also be Canon Log and it isn’t outputted with View Assist characteristics.

Histograms of images captured with [Canon Log] set to [On] are not based on images as converted for View Assist display. Image areas shown in gray in the histogram roughly indicate signal values that are not used.

[Color space] can be set when [Canon Log] is set to [On] and [Color Matrix] to [Neutral]. Choose [BT.709] or [BT.2020] as the color space for HDMI output.

HDR movie recording is not available with [: IS (Image Stabilizer) mode] set to [Digital IS], or when set to [ : Time-lapse movie], [ : Highlight tone priority], [: Canon Log settings], or [ : HDR PQ settings].

[IS mode] is not displayed when an IS-equipped lens is attached. If you attach an IS equipped lens then the [IS mode] is always activated and can’t be turned off.

Autofocusing is performed with a magnified display if you press the shutter button halfway when set to [Spot AF], and [1-point AF]. When set to AF methods other than [Spot AF] and [1-point AF], autofocusing is performed after restoring normal display.

Using a genuine Canon Battery Pack LP-E6NH/LP-E6N is recommended. If you use batteries that are not genuine Canon products, the camera’s full performance may not be attained or malfunction may result.

According to Canon, charging a depleted battery takes approx. 2 hr. and 30 min. at room temperature (23°C/73°F). The time required to charge the battery will vary greatly depending on the ambient temperature and the battery’s remaining capacity.

In Canon’s defense, they did issue a statement with estimated recovery times for overheating, but not every potential buyer of this camera may see that.

Do not remove cards immediately after a red temperature icon is displayed as you are shooting. Cards may be hot, due to high internal camera temperature. Set the power switch to and stop shooting for a while before removing cards. Removing hot cards immediately after shooting may cause you to drop and damage them. Be careful when removing cards.

The red icon indicates that movie recording will soon be terminated automatically. If this happens, you will not be able to record again until the camera’s internal temperature decreases, so turn off the power and let the camera cool down a while. Note that the time until movie recording stops automatically when the red [ ] icon is displayed varies depending on shooting conditions.

If there is a very bright light source in the image, the bright area may appear black on the screen. Movies are recorded almost exactly as they appear on the screen. Image noise or irregular colors may occur when shooting at high ISO speeds, high temperatures, slow shutter speeds, or under low light.

Movie recording is not possible as long as Temperatureicon is displayed. Display of the Temperature icon during movie recording also indicates that the camera will turn off automatically in approx. 3 min

It may not be possible to record movies during still photo shooting if operations such as extended Live View display increase the camera’s internal temperature. Turn off the camera or take other measures, and wait until the camera cools down.

Extended movie playback or movie playback under high ambient temperature may cause the camera’s internal temperature to rise, and movie playback may stop automatically. If this happens, playback is disabled until the camera’s internal temperature decreases, so turn off the power and let the camera cool down a while.

Although Canon doesn’t specifically state that you do this for EF lenses when using any of the EF-EOS R adapters, they do still state, ‘For lens precautions, see Attaching/Detaching RF Lenses.’

It’s ironic that Canon mentions this in the manual, but they say: Avoid adjusting the aperture value while recording movies, which will record changes in exposure caused by aperture adjustment. They also say: During movie recording, avoid changing the shutter speed, aperture value, or ISO speed, which may record changes in the exposure or create more noise at high ISO speeds.
