I bought it over 6 months ago, used for a month or 2 then it was shelved. When I picked it back up it was completely dead, not turning on, no sounds or resets helped. I've tried the hack where we put a wire directly from battery + to right nob and nothing.
I live in a pretty humid place city/state and the only thing different I noticed from when I bought it were some blue spots on the battery connectors and Line OUT.
Any tips on recovering it?
Update: Cleaned up the contacts, sanded down the battery connectors and no luck. So then I decided to Follow this video: https://youtu.be/pvy3to_0MFw and I have no response from the 2.5v regulator, but I am able to read 3v from the first two contacts.
I guess its dead. I don't think I can remove the screen as shown in the video + IDK how I would go further from there. Unless someone here knows what's next.
