TV not responding to remote and physical buttons
Today my TV a LG 47LM669S stopped responding to the remote control and also the physical buttons weren't responding.
After a while I couldn't turn on the TV anymore.
I disassembled it and took the physical buttons board out and now it seems to be working again with the remote.
Is it possible that the physical buttons unit (I don't know the right name for that) may be broken, we don't use it at all...
By looking at its PCB all seems fine not burn or discoloured parts, what can be a good test to make to check if the part is defective?
Can the IR board be faulty?
If the part (seems to be GP4 Control) is defective where can I find a replacement part in Europe?
Here some pics of the part:
