Re: Sony smart led tv kdl-46ex523 half screen white.
This would most likely be a bad LCD panel, unfortunately. Worth checking the ribbons going from panel to T-con as well.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?
By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the... -
I was asked to look at a Sony KD-55X8509C as it was not powering on, no lights.
On inspection, there was no physical issues.
I seated all cables and repowered the TV, then the LED light flashed Green / Amber.
- this seems to indicate repairing required, done by Firmware update.
so downloaded the latest Firmware from Sony website and wrote to 4Gb USB drive.
Inserted the drive and repowered the TV.
LED changed to white flashing/pulsing ... and it sat there for over an hour.
i was unsure what was happening so repowered the TV and now it just... -
This "free from a friend who was going to recycle it" SONY BRAVIA XBR-55A8H arrived with the bottom center RED LED repeating a four flash pattern. It was treated with kid gloves and was reported to have "just gone dead" and the OLED panel has no dents in the metal frame or cracks.
Thread https://www.badcaps.net/forum/showthread.php?p=1091829 helped in proceeding as follows:
1) Unplugged, then plugged set in while holding the remote VOL- and Power to factory reset.
2) Waited 30 seconds, then pressed remote Power button and "Select language"...01-30-2023, 05:01 PM -

Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...
