Hi, My friend gave me a damaged tv, I wonder if the Panel or the t-con, disassemble and tighten the tab but does nothing, has vertical lines that appear and disappear in different areas of the screen.
Thanks
Thanks

This is almost certainly a bad LCD panel, unfortunately.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Samsung UN46C6300 Bad Panel strange lines
I've an A-series Samsung doing this. Not sure on exact cause, but think it is related to VGL being too low, or VGH too low, haven't got around to fiddling with mine yet. If you set the image contrast down, does the image look better (excluding the menus)?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Looks like Tab bond problems on the display to me. Take a look here.

Re: Samsung UN46C6300 Bad Panel strange lines
Hi all,
Tom answering your question, no, low contrast when the lines are more marked. when more brightness or more colored lines disappear or not noticeable, but the entire image is very poor quality like a CRT monitor. strange.
Thanks Timall,
That's a good technique, but I want to try first what this before the panel and then continue with this step.Panasonic Viera TH-42 PX70B PLASMA-TV 42 The best TV 7 year and counting.Comment

Re: Samsung UN46C6300 Bad Panel strange lines
UPDATE** I could eliminate the fading lines, adjusting lower the sub bright in the service menu and the picture looks ok, but still very thin horizontal lines across all the screen. and the image looks like 480p low definition.
I found this video of how. with the same problem.

Hello Community,
I'm working on a Samsung UE70TU7020K.
It looks like a bad panel. There is only 1 FPC cable from the Tcon (built into mainboard) to the panel.
I'm using a piece of tap a few mils (covers about 8-10 pins), at different locations and have had varying results but nothing that is remotely watchable (multiple lines across all the screen, half screen and total black out on screen). The buffer board is divided into 3 boards. I've disconnected the end board one at a time but each time the screen was totally black. I presume it's because the potential...03-15-2024, 03:01 PM -
Hello all, I was recently repairing my Samsung 55" UN55JS9000 tv from the common burnt backlight LED's and cracked light guide panel issue. After replacing the LED's and putting the TV back together, I tested the tv and all I was getting was sound but no image. Somewhere along the way (could be related to the next issue) the T-Con board became damaged and after replacing it I have made a little bit of progress but now have bright pink vertical lines and still no image.
The bigger issue .... I took the TV apart again and realized that I likely didn't sit the LCD panel correctly... -

Well, I will be the first to admit that I screwed up...
In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.
I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.
I have 2 that I have found and have in my possession. ... -
I came across a 50inch TU8000 that wouldnt start up properly (blinking stand-by light, backlights would cycle on and off).
When i opened it up and removed the power to the mainboard the backlights powered up and everything looked uniform.
When reconnected the mainboard but disconnected the flex cable to the panel i heard the TV startup with the intro sound.
Later I checked for shorts on the panel PCB boards but could not find anything.
When I took a look with the FLIR i noticed the 2 resistors...08-10-2024, 08:39 AM
