Black screen on Sony 65x900h

[Adam Russ]

Yeah I send some messages to friends but no one seems to have any that small. Do you think a sd card is a usb reader would work to deliver the update? I do have one of those that small. But yeah I know I need to try it with the correct USB size to rule that out.

As far as errors, no. The green and amber were before this model. These would only blink red if there were any error codes. But it doesnt blink. And I can even play YouTube videos, just no picture. I guess I'll try the SD card route first since that will be quicker than waiting a few days for shipping on a 4gb flashdrive

I've tried SD card and it didn't work b4.. can't hurt to try though. And I've updated a 900h and had green and amber so not sure what you mean, I've updated later ones also and have had that too. Maybe I'm mistaken but pretty sure.

I feel like it's still the panel anyway, I've run into it b4 but sometimes your in too deep

Yeah, I mean if this doesn't do it I'm pretty sure it's the panel because everything else has been replaced with the same results. SD card didn't work. It did the same thing the other drives did where it makes a dozen other folders on the card (see photo). It's weird how it's so specific on. certain models, while I've used a 64gb thumbdrive to update my 83a90j without issue when I replaced the main board.

these files and folder are correct. acopy of yours Android system on TV.. it mean yours Main Boards 100% fine and the firmware too its boot and worked as it should..
useless to replace MB... the issue some where ells on the set... T-CON or Panel

Maybe checkout tcon voltages, check the tcon fuse too. Some testing there: https://www.youtube.com/watch?v=_hOMC2qn6jY

I'm almost going to guarantee it's not the t-con. When it first happened, I swapped the t-con with another of the same model and it didn't help. Then I even bought a replacement, which is currently in the tv. I doubt the same issue would be present across 3 different t-cons. I'm guessing it's the panel

That is very helpful. It must be the panel then (unfortunately) because everything else has been swapped without no change. And 3 t-cons have been tried. > know it's not the main board. This is the third main board that has been in the tv now and nothing changed. Only thing I wasn't sure of is if the update was being applied but you're saying those folders being created means it worked correctly. if that's the case, then it's the panel itself.

Had a little more time today so I messed with the tv a little more. I unplugged the right side ribbon cable to the panel and played around with blocking out some clock pins on the left ribbon cable. I got an image (not perfect but watchable) on that half. Plugging in the right side it goes back to black images. I unplugged the left side and have been working on blocking clock signals on the right side bu haven't been able to get a picture from that side yet

Samsung has had a lot of crap panels that short out in the last few years, models like the TU, KU etc.
Almost every 4th Samsung coming in is having a panel problem.
