Have had this sitting around and repaired power board and got backlights but still had no sound or video. could not find anything wrong on Main so I got another board. Then I got white screen so now I just got a t-con and upon initial fire up got verticle colored lines all across panel. Turned off and on, got just backlights again. Took apart and messed with t-con ribbons. the two outer ones when I disconnect give me white screen. The two inside ribbons when disconnected one at a time I get lines on either side. Here Are some Pics and looking for ideas. Thanks

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... -
Good afternoon! Does anyone know how to remove these lines? They are very fine lines at the bottom of the panel. I have 2 identical panels, and I have even thought that this brand has this lattice format, although I highly doubt it.
The photo from the YouTube app is where it is best seen.
thanks in advance.... -
49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.
Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on... -
No picture ,tv appears to turn on and off using remote as standby led goes from red to nothing when on and red again when off
. Backlights also light up when tv is powered on.
Removing panel ribbon cable from left side screen still dark.
Removing panel ribbon cable from right side the right panel is white and left panel is dark but within a few seconds the left panel has a large green vertical bar and beside it many thin red lines.This whole screen dims down to dark within a few seconds and the right side slowly turns white again.
. Tcon gets 12 volt
. Tried taping...
