I have a Sony 75x940e that I just fixed with the help of the forum (bad emmc). For the last couple of months I was noticing some burn in of the android home icons on dark backgrounds (photo is attached). I always thought VA panels were immune to burn ins. Is there anything I can do to fix it? Could it be because of a failing component other than the panel itself?

by howardc64Eventually discovered a burn mark near lower corner of LCD. Here is a summary
- Backlight on, no image
- Disconnect right buffer board (view from front), left side display comes on
- Masked off pin 7+8 (both ~12,5v on both left and right buffer board) from t-con to right buffer board (view from front) display works but have some lines
- Buffer board is pretty simple

by iglitareHi,
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... -

900H: model yr 2020, Samsung panel
930D: model yr 2016, Innolux panel
spec wise the panels are the same. the drivers and tcons are obviously different but what made me want to give this a try is that the wiring diagrams for the data signals going into the tcon for each tv were nearly identical. there are only a couple pins that i am unsure about and that is what brings me here.
the 930d has the DPS board where the 900h has none, however, if you follow the pins to the BM1 it would appear that the signals...07-11-2023, 11:11 AM -
by guidodroidHello all,
I'm trying to understand what is the issue with my 26 months old Sony Bravia KD-65XG8505 (XBR65X850G).
It is just few months out of warranty, so Sony doesn't want to do anything, and the local replacement shop also tells me that it's not worth repairing (alhtough this model costed almost 1000 euros just 2 years ago...).
Few nights ago the TV started showing some horizontal lines and distorted colors/geometries in the bottom part of the screen (see attached photos).
The issue is not as bad as others that I've seen around, but is indeed noticeable... -
by PlanBHello everybody,
I need your expertise if my asumption about the failure of this TV is correct.
A Sony KDL-55W828B only shows vertical red stripes that vanish to the top when switched on.
When only the right side of the LCD is plugged into the T-CON board the right side shows a good image, while the left side is white.
When only the left side of the LCD is plugged into the T-CON board the LCD shows a complete white image.
I checked some signals on the T-CON board but was not able to find something strange. Then I checked the the caps... - Loading...
