That was my problem...
It was oxidation on the connector on the LCD board itself...
After cleaning and re-soldiering was better but still bad..
Eventually I got a replacement

Hi Ozko,
Do you have a photo showing where exactly you found the oxidation?

Thats the connector but this one is fine...
The other one was green from oxidation with stuff between the pins
