LED panel type for QE75Q60RAT

[marekk]

Hi,

I'm trying to repair 75" QE75Q60RAT with a faulty main AV board after a lightning strike.
I got a main board for 55" QE55RU8000 which works in this TV but the picture is bright with very low contrast.
In the service manu I have changed LED panel type to 75" 75L1AU0NR but that didn't help, unfortunately.

Could you let me know which panel type is in the service menu for this model?

TV is based on CY-RR075FGHV1H

I would be very grateful

Best regards
Marek

Here you need to carefully compare the boards, there are positional resistors (they can be set to different panel diagonals) and you need to rearrange the spi flash 25Q80 from your native motherboard, this flash T-CON, it contains all the settings for your panel...

Thank you will try that, in the past I have successfully moved screens (glass only) between 55RU8000 and 55Q60rat so I know that either mainboard can work with this panel but now the sizes of the panels are different.

Indeed I have found many differences between those mainboards.
Unfortunately, after I changed several resistors, removed one DC/DC regulator swapped 25Q80 flash, board works worse than before.
TV does power cycle with backlight only, no even logo displayed.
