Yep so I went today to the repair shop and paid 10euros for a diagnostic. He told me is the T-Con board and said that it will cost me an aditional 57euros for the board itself + 20e for the montage of it. But at that time I already seen
Daves link where the same board is 30$ so I was like alright, I'll have some time to think about it. I may buy it from somewhere else and use
Framaris example of youtube helpful tutorials to put it in there myself. Or... Or just pay the guy to do it. Depends if I get enough money tonight by selling my body to random lonely strangers.
Either way, I thank everyone for their posts and probably will do an edit later these days if I actually fix it somehow.
