how to fix lcd display in stock

Ok, I just had this problem, tried tried to flash the firmware, specifically the firmware_bltouch.bin. turned the printer off, inserted SD card, firmware.bin renamed to firmware.cur (finally pulled the card out after waiting 10 minutes). Blue screen, completely blank.

copied the firmware.bin that came on the SD card. Inserted, nothing. Didn"t rename the file. when I looked closer, I noticed that my file was named, FIRMWARE.bin. All caps name, lowercase extension. Made extension all caps, inserted. Flashed back to original firmware that came with the board.

Then I noticed that the firmware.bin and firmware_bltouch.bin that I downloaded from github, via right-click, save as was only 82KB. While the firmware that came with the board was 209KB. This didn"t seem right, so I went back to github and instead of downloading via right click, I clicked on the firmware_blthouch.bin. This loaded a page that said the file ws 226KB, with a download button. Clicked download. Verified that the file was indeed 226KB when downloaded. Renamed it to FIRMWARE.BIN, inserted into SD Slot, turned on printer. 15 seconds later, the screen loads and says I"m on the newer version of Marlin (2.0.6, I think).

So, I am a bit of a dumbass, but in case it might help others, make sure your downloaded file is 200+KB in size, and not 82KB. And renaming to all caps fixed my restore, so I didn"t even try the new firmware.bin file lowercase, I just made it all uppercase.

Apple has determined that some iPhone X displays may experience touch issues due to a component that might fail on the display module. An affected device may exhibit the following:

Choose one of the options below to have your iPhone X serviced. Your iPhone will be examined prior to any service to verify that it is eligible for this program.

If your iPhone X has any damage which impairs the ability to complete the repair, such as a cracked screen, that issue will need to be resolved prior to the service. In some cases, there may be a cost associated with the additional repair.

If the picture responds to input but displays a messy image, such as jumbled multicolored squares, the AV (audio visual) board may be damaged. This is usually a rectangular circuit board located near the audio and visual cables. Replace obviously damaged parts using a soldering iron, or order a replacement board and carefully install it to the same screws and ribbon cables.

The main control buttons may be faulty. Clean them with a metal cleaner, or jostle to attach a loose connection. If necessary, locate the circuit board they are attached to and re-solder any broken connections.

Check input cables for damage, or try other cables of the same type. If necessary, inspect the circuit board they are attached to and re-solder damaged connections.

Once you have found the correct part number, see HP Consumer Notebook PCs - Ordering HP certified replacement parts. Use the instructions in this document to order a replacement part.

I’m not sure if there is an OLED replacement but I doubt it would work for it. OLED is more energy efficient and has better colors but it not only costs more, it functions differently from LCD as far as I know. If you want a phone with an OLED panel, it would probably be best to buy one that already uses it.

In my case the ribbon was half detached. I took the pen solder bold and set it to 180 °C and slowly moved several times with medium pressure along the ribbon and pressed it onto the plate. I had to repeat this procedure 3-4 times until all pixels were working again.1

I investigated my landline phone to repare its LCD according to this good tutorial, unfortunatly I found the cutted connection is not on the main PCB board but on the flat connector itself... and any heat applied (soldering tentative...) to the flat is going do destroid it completly ((

Instead of hot-air gun use hot melt adhesive (https://en.wikipedia.org/wiki/Hot-melt_adhesive) gun. Just use its hot spike, and you will be able to point precisely to the place you need a heat.0

Unfortunately, after two days the display started to lose some segments. What would other people recommend? Is this expected and should I have done something else other than heating and rubbing with an eraser?

Many thanks for sharing the information on how to fix these displays! Worked out perfectly on a asus lcd poster from ages back which gave no screen at all and are not sold anymore to replace.ReplyUpvote

Very good interesting piece. I am no way shape or form of an electronics junkie , but i am more like a jack of all trades and a master of none type. I have a dual power TS-100 hand held calculator where the second digit was pixelated I would say. I googled how to repair it and seen your story. I took my calculator apart and the back side is where that glue strip is at. I could not find my heat gun, thanks to having to move it for the Christmas tree setup. I used my Kitchen Propane stove front burner and waived it over it a few times. It took a few tries but I finally was able to get the dead pixel back. One good thing is the calculator was on so in between heat ups and eraser rubbings I could see my progress and man your fix really worked. Thanks fro the story. My favorite pocket calculator is fixed once again. I wish I would have taken before and after photos, but was too giddy to try your repair idea.0

Google offers no link as to how to open an AEG Voxtel D235 handset. After opening the battery compartment and removing batteries and the two Philips screws at the bottom, the upper half refuses to budge. Is there a method for opening the upper part, to access the LCD screen connector for repair? Any suggestions appreciated.0

This made me squeal when it worked! I fixed an old treadmill computer from a machine I bought second-hand. There was a broken connection on the breadboard so I dunno if that work but we"ll see! I didn"t have a heat gun, blow dryer or clothes iron to use, but I made it work with the end of my hot glue gun. Thanks, God bless!

I just got my CM921 to work - so, carefully unplug or remove the lcd unit from the circuit board (8 pins i think) then separate the white board (same size as the lcd) from the back of the lcd display (it was glued on one side and i used a scalpel) the lcd will then flip over and you can see the ribbon, then follow the instructions above, return the lcd back down on top of the little white board as before and plug it back in...0

There may be a thin conductive rubber strip between the glass of the display & the board it is attached to. Over time this rubber can leak an insulating compound onto the interface connection that can, at times, be removed by removing the strip and gently rubbing it with a clean soft eraser. Be gentle as it can be fragile & easily damaged. This was an effective repair in the early days of these displays.0
