how to reset tft lcd monitor in stock
If you spend long hours working on your computer, adjusting your LG monitor"s settings can increase your viewing comfort and prevent eyestrain. The LG monitor features a super energy saving mode that adjusts the brightness to a lower, more comfortable level while saving your business money in energy costs. You can reset super energy saving mode if you want to clear the settings. The LG monitor also has a factory reset option that enables you to erase all custom settings.
That annoying dead pixel on your TFT, OLED, or LCD screen might just be stuck and easy to fix. We"ll show you how to do it. You can still return your monitor if this doesn"t work; nothing we recommend here will void your warranty.
Yes, you should test any new monitor for bad pixels. You can simply run your screen through a palette of basic colors, as well as black and white in full-screen mode using a tool like EIZO Monitor Test.
EIZO Monitor Test is an online tool that lets you find and eventually fix stuck pixels. It packs many options into a single test window, but it"s easy to use once you have an overview.
To test your screen, check all the boxes you want to include in your test. We recommend the default setting of having all boxes checked. If you"re testing multiple monitors, you can open the test on an additional monitor. When you"re ready, click Start test to launch the full-screen test window.
Below you see the first test pattern. Each screen has an explainer in the bottom right detailing what you should look for. Next, you"ll see a menu that lets you go from one test to the next on the left. Move through the black and white screens and all the solid colors (green, blue, and red) and check our screen. To exit, press the ESC key or the exit symbol in the top right.
This is a very thorough test not only meant to identify bad pixels but also powerful enough to test the quality of your monitor. Unfortunately, with Flash no longer supported by most browsers, you"ll probably have to use the executable version to make it work.
Move the mouse to the top of the test window, and a menu will appear. There is an info window that you can turn off with a button in the top right corner of the menu. Then click on the Homogenuity test point and move through the three colors as well as black and white.
A stuck pixel, sometimes wrongfully referred to as a hot pixel, is defective because it receives incomplete information. Hence, it appears in one of the colors that its three sub-pixels can form, i.e., red, green, or blue. Strictly speaking, hot pixels only appear in digital cameras when electrical charges leak into the camera"s sensor wells. Sometimes, stuck pixels fix themselves.
In a dead pixel, all sub-pixels are permanently off, which will make the pixel appear black. The cause could be a broken transistor. In rare cases, however, even a black pixel may just be stuck.
Unfortunately, you can"t fix a dead pixel. You can, however, fix a stuck pixel. As I explained above, it"s hard to tell the two apart. Either way, these are the methods you can try:
The tool will load a black browser window with a square of flashing pixels. Press the green button in the bottom right to go full-screen. Drag the flashing square to where you found the stuck pixel and leave it there for at least 10 minutes.
UDPixel, also known as UndeadPixel, is a Windows tool. It can help you identify and fix pixels using a single tool. The program requires the Microsoft .NET Framework. If you"re not on Windows or don"t want to install any software, scroll down for the online tools below.
Should you spot a suspicious pixel, switch to the Undead pixel side of things, create sufficient amounts of flash windows (one per stuck pixel), and hit Start. You can drag the tiny flashing windows to where you found odd pixels.
The PixelHealer lets you flash a combination of black, white, all basic colors, and a custom color in a draggable window with customizable size. You can even change the flashing interval and set a timer to close the app automatically.
Let it run through all colors in Auto mode to spot whether you have any weird pixels on your screen. If you do, start the fix, which will rapidly flash your entire screen with black, white, and basic color pixels.
Should none of these tools resolve your stuck or dead pixel issue, here is one last chance. You can combine any of the tools detailed above and the magic power of your own hands. There is a very good description of all available techniques on wikiHow. Another great step-by-step guide can be found on Instructables.
This works because, in a stuck pixel, the liquid in one or more of its sub-pixels has not spread equally. When your screen"s backlight turns on, different amounts of liquid pass through the pixel to create different colors. When you apply pressure, you"re forcing the liquid out, and when you release the pressure, chances are the liquid will push in, spreading around evenly as it should.
When all attempts to revive your bad pixel fail, the next best thing you can do is to make peace with it. One ugly pixel won"t break your screen, and eventually, you"ll forget about it. If the defect affects more than a single pixel, however, or just bothers you a lot, you can always replace your monitor.
First, check the warranty. The manufacturer or the marketplace where you purchased the monitor might cover dead pixels. Note that most manufacturers define a maximum number of allowable bad pixels for specific resolutions, and the warranty won"t apply until your monitor crosses that threshold.
Bright or dark sub-pixels can occur during the production of the LCD Monitor panel but does not affect the LCD Monitor functionality. The customer may notice the bright or dark spots if the film of the liquid crystal does not perform as expected while customers uses the LCD monitor. However, this is not considered a defect unless the number of bright and dark subpixels exceeds the maximum allowable threshold (...)
On a monitor with over 12 million pixels (Wide QXGA+, 2560x1600 pixels), for example, LG"s pixel policy says that 12 bright or dark sub-pixels is the maximum you have to tolerate.
Should all of these approaches fail to fix your dead pixel warrior, at least you"ll now know it"s not simple to fix, and, you might actually have to replace the screen.
It is estimated that there are around one billion personal computers around the world, and with every single desktop computer, there is also a monitor attached to it. Every day, hundreds of computer monitors break down, and if you have a LCD monitor that you bought fairly recently and have questioned why it won"t turn on anymore, it"s most likely a power problem that can be fixed to save you hundreds of dollars. This guide will specialize on the computer monitor model LG L196WTQ-BF, but most monitors will follow similar design and can generally be fixed using the same instructions.

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.
2) Connect the TF card to the PC, open the Win32DiskImager software, select the system image downloaded in step 1 and click‘Write’ to write the system image. ( How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details)
3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)
1. Executing apt-get upgrade will cause the LCD to fail to work properly. In this case, you need to edit the config.txt file in the SD card and delete this sentence: dtoverlay=ads7846.
This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.
Article Summary: This article helps you find information about your Dell SE2417HG Monitor like how to setup the monitor, how to use the monitor and some troubleshooting methods to resolve the most common monitor related issues.
The Dell SE2417HG flat panel display has an active matrix, Thin-Film Transistor (TFT), Liquid Crystal Display (LCD), and LED backlight. The monitor features include:
This section provides some specifications of the Dell SE2417HG Monitor. For more information about the Dell SE2417HG Monitor, refer to the User"s Guide at the Dell Support website.
Connecting the Monitor - Refer to the knowledge base article How to Connect a Monitor to a Computer?. Alternatively, you can also refer to the Setting Up The Monitor in the User"s Guide for your Dell SE2417HG Monitor.
Ports & Connectors - Refer to the User"s Guide for your Dell SE2417HG Monitor for more information on the Ports & Connectors available on your Dell SE2417HG Monitor. Back to Top

Your Dell SE2417HG Monitor provides a self-test feature that allows you to check whether the monitor is functioning properly. If the monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove the video cables (VGA, DVI, HDMI or DisplayPort) from the back of the computer.
If the monitor is working correctly, it detects that there is no signal and one of the following message (Figure 2) appears. While in self-test mode, the power LED remains white.
If your monitor screen remains blank after you use the previous procedure, check your video card (GPU) and computer, because your monitor is functioning properly. Back to Top
Your Dell SE2417HG monitor has a built-in diagnostic tool that helps to determine if the screen abnormality you are experiencing is a problem with the monitor or with the video card on your computer.
When you notice screen abnormalities like distortion, clarity, horizontal or vertical lines, color fade etc., it is always a good practise to isolate the monitor by running the Built-In Diagnostics.
Note:If you do not detect any screen abnormalities upon using the built-in diagnostic tool, the monitor is functioning properly. Check the video card (GPU) and the computer.
If you notice any abnormalities during Built-In Diagnostics, you may get the monitor repaired/replaced if it is under warranty by contacting Dell Technical Support.
Press Button 1 to bring up the Input Source menu. Use Button 1 or Button 2 to toggle between VGA or HDMI source and then press Button 3 to confirm your selection (Figure 3).
A few permanently bright or dark pixels are considered normal by industry standards. The exact number of pixels allowed varies depending on the monitor. Refer to Monitor Quality and Pixel Policy for more details.
Note:If you do not see the recommended resolution as an option, you may need to update the video card (GPU) driver by visiting the Dell Support website.
-It will power up on as little as 5v DC! I wired it to the power leads of a USB cable, and to my surprise it came on! My idea of running both the Pi and the screen on an RC car battery may not be so far fetched after all! :)
-It really is small, 3.5" isn"t much space to work with. GUI mode requires more work than I have already put in to make it readable in all programs, but I"m sure it can be done...
-It is not as clear as HDMI or even VGA for that matter. Remember old analog TV broadcasts and how the text on the evening news looked? Yeah, a bit like that.
-It has a noticeable flicker. I don"t know if this is due to the screen itself or the fact that I have compact fluorescent lighting (Remember the old days of CRT computer monitors? Had to crank the refresh rate up from 60Hz to 75Hz to get rid of the flicker under fluorescent lighting) I"m not yet sure if the refresh rate is adjustable. It may require a hardware hack that is beyond my current skill level.
The bad news really isn"t all that bad when you consider that it is using an analog connection. However, if you are expecting the sharpness and resolution that is available on current smartphones, you will be sorely disappointed.
I have cracked the housing open to see how hackable it is and found that the ribbon cable that goes from the controller board to the LCD screen is about the same size as the ribbon connector on the Raspberry Pi (Model B) that has been identified as a display connector. I have no idea if it would work and I didn"t want to risk causing irreparable damage to the screen in the process of finding out. So I left it as it was and reassembled it. It would be interesting if this screen could be hacked to accept a digital input...
WARNING: BTT does not officially provide MKS TFT hardware support. MKS TFT is maintained by open source contributors and BTT does not bear any risk of MKS TFT hardware using this firmware.
IMPORTANT NOTE: The Master branch is currently the ONLY branch in the project to be used. The other currently existing branches develop and release-xx.27 are outdated and MUST NOT be used.
In case your mainboard provides EXP1 and EXP2, you have to connect 2 ribbon cables connecting EXP1 and EXP2 of the mainboard to EXP1 and EXP2 of the TFT. In the Marlin firmware of your mainboard, make sure that ONLY REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER is activated in Configuration.h and that all other controllers are Deactivated (especially CR10_STOCKDISPLAY).
In case you have an "E3" mainboard which provides a single EXP connector, you have to connect 1 ribbon cable connecting EXP of the mainboard to EXP3 of the TFT. In case your TFT does not provide an EXP3 connector but only two 10pin connectors (TFT24 v1.1 for example) you will need a "Y-split" cable with one 10pin connector on one side (for the mainboard) and two 10pin connectors on the other side (for the TFT). In the Marlin firmware of your mainboard, make sure that ONLY CR10_STOCKDISPLAY is activated in Configuration.h and that all other controllers are Deactivated (especially REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER).
Any binary file for an MKS firmware (e.g. MKS_TFT28_V4.0.27.x.bin) MUST be renamed to MKSTFT*.bin (e.g. MKSTFT28.bin, MKSTFT35.bin etc.) in order it can be recognized and installed by the TFT
The firmware configuration can be modified by changing the config.ini (or the renamed config_rrf.ini) file using a simple text editor (make sure to use UTF encoding).
A configuration can be uploaded without the need to upload the firmware or the TFT folder again, as long as the firmware and the configuration file are from the same version (see Configuration Update).
NOTE: For devices with USB flash drive support, it is possible to update the icons, fonts, config and the language files from a USB flash drive in the same way it is done through an SD card. However, the firmware can only be updated using an SD card.
Copy the precompiled BIGTREE_TFT*_V*.*.*.bin or your self compiled firmware, plus the TFT* folder of your preferred theme along with config.ini to the root of a blank SD card not greater than 8GB and formatted as FAT32:
Optionally, copy one or more language_*.ini file(s) onto the SD card. Doing so, it will allow you to switch between English and the uploaded language(s) from the Language menu present in the TFT firmware. We recommend to upload the minimum amount of languages to keep the memory usage low. The language_*.ini file can be edited to change the text shown on the TFT:
Place the SD card with BIGTREE_TFT*_V*.*.*.bin, the TFT* folder, config.ini and the optional language_*.ini file(s) into the TFT"s SD card reader and reset your TFT (or optionally - power cycle your printer) to start the update process:
In case one or several parts of the update failed, an error will be shown. Follow the information on the screen to update the missing or outdated elements:
After the update is done and the files are renamed, it is possible to reuse them again. To do so, change the name of the element(s) to the pre-update name and start the update process again.
Touch Screen Calibration menu: A post installation process is needed before switching to Main menu. Please, see Post Installation section for completing the post installation process
In case major changes have been applied by the installed firmware, a post installation process consisting on touch screen calibration is automatically started.
For devices with USB flash drive support, it is possible to update the icons, fonts, config and the language files from a USB flash drive in the same way it is done through an SD card. However, the firmware can only be updated using an SD card
The hard reset process is typically used as the last chance when the firmware is not properly working (e.g. in case of freezes, errors on screen etc.)
Unless the default hard coded settings have been properly configured (e.g. a self compiled firmware was installed), after an hard reset the TFT typically needs to be reconfigured with the proper config.ini file (see Configuration Update)
When the default hard coded settings are properly configured for a TFT and the TFT"s basic function such as surfing on the menus is working, in case of issues the user can opt to apply only a configuration reset (soft reset) instead of an hard reset.
A BIGTREE_TFT*_V*.*.*.bin file will be generated in the hidden .pio\build\BIGTREE_TFT*_V*_* folder. Follow the update process outlined in the Firmware Update section above to update your TFT to the latest version
TIP: In case there is a problem compiling the TFT firmware try to restart VSC. If this does not help and you are using macOS, delete the packages and platforms folders usually present under the folder /Users/***username***/.platformio/.
All the precompiled firmwares available on Copy to SD Card root directory to update folder are compiled to support the standard (horizontal) screen orientation.
In case the TFT needs to be placed with a vertical orientation (e.g. 90°), the firmware needs to be compiled with the portrait mode support and installed following the procedure below:
NOTE: With only power supplied, you should be able to navigate through the menus using the touchscreen and even to switch to Marlin Mode (if available). Marlin Mode will not show any interface without a proper EXP connection (see Marlin Mode Setup).
OctoPrint, ESP3D, Pronterface etc, connected to a TFT"s serial port, can browse files on both the TFT"s and mainboard"s media devices and start a print that will be handled by the host (TFT or mainboard). The following actions and the related triggering G-codes are currently supported by the TFT fw:
OctoPrint, ESP3D, Pronterface etc, connected to a TFT"s or mainboard"s serial port, can host a print (print handled by the host) and optionally can trigger some actions to the TFT sending specific G-codes. The following actions and the related triggering G-codes are currently supported by the TFT fw:
Only on print end or cancel (with triggers print_end or cancel) the TFT Printing menu is finalized (statistics available etc.) and unlocked (the menu can be closed).
With the exception of TFT70, the maximum number of displayable layer count is 999 (there"s no space to display layer number and count if the layer count is above 999)
The other type is to store the thumbnails using dedicated comments (thumbnail begin... and thumbnail end) which is implemented in stock by some slicers like Prusa-Slicer.
The most recent version of the standard bigtreetech TFT firmware has built in support for RepRap firmware. The pre-built images have this enabled by default.
The TFT35 E3 V3.0 has 3 cables to connect to the mainboard. Two 10 pin ribbon cables and one 5 pin serial cable. The 2 ribbon cables connect to the EXP1 and the EXP2 connections on both the TFT35 E3 V3.0 and the MKS mainboards.
The RS232 cable is connected to the RS232 connection on the touchscreen, with the other end connecting to the AUX1 connection on the mainboard. The RS232 cable has 5 wires. One end has a single 5 wire connector that goes to the RS232 connector on the touchscreen, and the other end has two connectors, one has 4 wires, and the second one has one wire. That single wire is for the Reset and is not used on these MKS mainboards. The 4-pin connector plugs into the AUX1 connection. It must connect to the top row of pins when looking at the socket with the notch facing away from the mainboard and must be also plugged in with the 5v+ wire connected to the first pin in the upper left corner of the socket. The RESET wire is not connected to anything.
NOTE: On the MKS mainboards there is an issue that involves at least the MKS GEN_L, MKS SGEN, and MKS SGEN_L models. The EXP1 and EXP2 connections have the socket shell installed wrong way around. The notch that indexes the cable should be facing towards the mainboard. If you get a blank screen on the TFT35 E3 V3.0 touchscreen after connecting the two EXP cables and turning the printer on, turn printer off and disconnect the 10 pin cables from either the touch screen or the mainboard and using small diagonal cutters trim the tab down to be as close to flush as you can get on both cables (and only on one end) and plug them back in with the trimmed tab now facing the mainboard.
The second workaround for this issue is to carefully pry the two shells surrounding the pins on the mainboard upwards until they clear the pins. Do NOT use a metal tool for this, use a sturdy plastic or whalebone prying tool. Turn the shell 180 degrees and align the pins with the holes in the shells and push the shells back on with your thumb. Do not push the shell back on with something that could cause damage if it were to slip. Once the shells are installed you can use the stock (unaltered) cables as they are.
Edit the Configuration.h file and enable (uncomment) REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER. Rebuild and deploy the Marlin firmware to your 3D Printer.
Statistics as filament length, filament weight and filament cost can be embedded into the G-code. After the print is finished there will be an infobox that you can click and a popup will present you the printed filename (limited to the first 25 characters), the time needed for the print, the filament length used, the filament weight and its cost. In the case of multi-filament usage the statistics will show the sum of all individual data (sum of length, sum of weight, sum of cost).
In case filament data is not present in the G-code, the filament length data is calculated during print. Length is calculated regardless of using the TFT USB, TFT SD or the onboard media. Calculations are done in both absolute or relative extrusion mode. Filament data takes into account the flow rate also but with a caveat. It has to be the same flow rate during the entire time of the printing, because the end result is calculated based on the flow rate at the time the print has finished. If flow rate changes during the print the results will not be accurate anymore.
