Tv Lcd LG 26LD350-ZA - picture divided into 4 parts

[Smartec82]

Good afternoon,
This TV has the picture divided into 4 parts.
I have already tried to fix it in the service menu but without success.
Does anyone know if it will be a problem setting the display size or the display itself defective?
Thanks for any tips.

Is this happening on all Video sources?

I've changed lcd type, lcd size and model etc ... in the service menu, but incredible as it seems the picture still gets worse.
I've been checking the main board better and it looks like the tv already came from another workshop, because it says 32ld450ips when it should have 26ld35auo and maybe this problem.

if you look on shopjimmy it may tell you the alternative boards you use in this set but i would try and source the correct mainboard for the tv your working on, like you say it may of just been swapped for the wrong one and may not be fully compatible with the lcd panel.

Ah, the missing information about what was done to this TV.

Hello,
The mainboard is not suitable for TV, it was adapted, but I was told that it was a defect in the panel, rather a defect in COF. Also after a short time, the panel in the corners gets the colors stained and burned as in the plasma panels.

Thanks for tips.

Hi
I've already been able to fix the TV without having to switch to a correct mainboard.
Through a friend, who sent me some neat photos on the bottom of an orginal mainboard, I could see that the R206 of 1k had to be removed and put it in position R207.
I checked in the schematic and on page 19 in Model Option, I saw that the R206 is for Full HD and the R207 for HD.
