First thing you need really is a schematic, so you have a clue where to look.

Sorry i ve searched on the internet but it seems no shematics online
but i ve got another working receiver the same one.

It looks like someone has been messing with it in the past; there seems to be some dubious soldering & possibly damaged PCB traces around the centre right position in photo 1039.

I'd examine that area carefully with a good light and magnifier & try to fix any bad joints etc.
