    SAmsung LE52A656 - panel fault or not?

    Hi guy I got this samsung LE52A656 on the bench.

    The fault is vertical and or horizontal blocks/lines on screen

    Apparently it is intermittent and the TV sometimes works, haven't seen it myself but when I picked it up it did have a proper picture on screen with some lines/blocks in part of the screen. I have no reason to doubt the owner.

    There are 4 TCON cables I tried disconnecting them in turn but couldn't get a good picture. However disconnecting each TCON in turn does affect the screen.

    Here's some pics. Really I want to determine if this is a panel fault or not. Sorry the pics are not brilliant, I was on my own and couldn't hold the camera far enough from the screen as it is so large.

      Panel problem. If you flex the panel, does it make any difference?

          you might ask the owner who was the "window washer"... maybe... :-) probably not recoverable as it appears to be a major issue with the panel.

              Samsung UE55JU6800K half screen dark
              by Chrissygizmo
              Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
              I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

              Samsung QN75Q6FNA backlight no display, red LED blink 2x, fault in panel
              by howardc64
              • Prior owner tried a replacement main board. No difference.
              • Samsung 2x red blinking standby LED = panel fault
              • Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
              • Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
              • Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display

              samsung galaxy ao2s very temperamental after screen replaced
              by Chrissygizmo
              Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
              Ive eventually managed to get it on and working but it's very temperamental...

              The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...

              SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.
              by triplefour
              TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.

              tcon is built into mainboard.
              Only one cable goes to panel boards.
              there is a cable from one panel board to the other that links them.
              cost cutting measure that results in us having harder time to diagnose.
              removing the link to the second panel board allows TV to stay on with stable backlight but no image.
              used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board....

              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
              by Ryan.man
              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...
