So I foolishly attempted to clean the inside if my PS4 and I ripped off the 4 pin power connector from the board. Can you guys fix this and how kuch?

Yes, I can fix that it is hard to say a price without a visual inspection of the system, I provide a free visual inspection at the time of drop off. but to answer your question, it will likely only be $20 more if I must rebuild traces or remove the motherboard

I think its 40$ to 100$ don't quote me lol
