this is not luck subject... OLED are RGB micro LED in simple language... some get bad, but from my way experiences SONY / LG they handle this via firmware register and if it meant or not after use over 10000 hours the firm ware will register fault.. however there could be no fault...... after courts and claiming Philips OLED TV released binary ( i posted here ) to remove this action from boot... but other company didn't till now... so you can keep it in save place till this wounder happen from SONYComment

Hi,
i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
Backlight seems to work, Sound (Setup menu after reset) works.
If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
With my small knowledge i would think at least the cables are good.
Can this happen because of a bad tcon board?
Or is it always a bad/shorted... -
Hi there,
I see a couple of posts related to the troubleshooting of similar TV. The one I have is acting slightly differently and I'd love your help.
So it has the 5 blinks. Previous owner got a TCON, no luck. Got a new Main board (though he didn't do the USB firmware update), again, no improvements.
I see 2 posts that are relevant:

Hello all ~
Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.
When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.
I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped... -
The TV shows a black screen with no image.
TCON ribbon connectors were disconnected individually for image and there was no half image even.
Later both ribbons were disconnected and TCON voltages were tested.
12V, 3.3V, 1.8V were seen present but VONE signal reads 0V.
There is also a short to ground in this circled inductor.
Is this a TCON issue or something else ?... -
Hi,
I have this problem with my Sony 55' AG9.
It flashes 4x.
I have found the service manual, and seems it is the TCON.
Before I buy a TCON can someone check the vid?
Thanks in advance!...
