    Seiki Se65gy25 grey screen

    I have done a ton of research on Seiki repair and have had no luck finding anything. Unfortunately Sieki has some of the worst customer service I have ever experienced. It started one morning when I turned the TV on I saw a grey screen slowly appear from the bottom up in a hazy crawling motion. It still has sound. I replaced the TCON board with no luck, actually might have made it worse, so I put the original back in and ordered a main board. The new main board fixed the issue for about two weeks. Now I see the same crawling grey screen every time upon start up in the morning. Occasionally a power reset will get it working but I usually have to let it run for ten minutes and then do a power reset. Could be a heat related connection issue?

    The most recent issue has been an error message when trying to play a playstation3 through the HDMI which reads "unsupported data" with blue screen behind it. Yet at the same time I can switch the input to the cable box and that will work, also an HDMI port. The same thing occurs where I have to reset TV or let it run a while to get the error message to stop. If you have any suggestions please let me know. Thank You.

    Please could you post pictures of the circuit boards and back of the set with cover removed.

    Have you taken any voltage readings on the power supply board.

    Do any of the capacitors look as though the tops are bulging?
    Willing to help but I'm no expert.

          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...

          iphone XS turns off when press on screen.
          by smic717394
          Hi,

          I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

          Chinese multimedia crashes on the home screen, could someone help with the software or factory reset?
          by LEONARDO DE FREITAS
          Hello everyone, I have 2 multimedia systems with a 9-inch screen that turns on and only stays on the Android screen. It is very likely a software update. I have 2 software programs here but the multimedia system does not start the installation. Has anyone encountered this problem? I would be grateful if you could help.

          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...

          ipad pro 9.7" blew a SMD component while replacing the screen 🤦‍♂️
          by ipatch
          i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...
