Same model different size switching main boards- problem

Post by Lindan »

Hello everyone... this is my first post here but im reading samygo forum for some time.
So i have problem with changing main board.. I have issues with my main board so i bought another one which i tought it was the same but it is not..
my tv model UE50MU6172uxxh
and the main board i bought from is model UE43MU6172uxxh

I was reading that you need to do eeprom reset because those two main boards are a bit different but i really dont know how to do that.
If somebody can explain it if it is possible to make this one work..i can screenshot you both mainboards..thanks ahead..have a nice day

check service manual for some hints.

Does the new board work. Maybe you have wrong connection on some cables check T-CON etc...
