Greetings.
So, a good long while ago, my friend lended me his Gameboy Pocket. I used it for Poke-purposes, and then had it in a drawer for months. When I wanted to return it to him, I found that it no longer turns on.
There's no power, the LED doesn't come on, and the screen doesn't come on. However, a faint hiss can be heard if I put my ear up to the speaker. It's like if you turned on a stereo and didn't turn on any music. Just an idle speaker sound, y'know. Does that make sense? Furthermore, I noticed (after taking it apart) that after I turn it on, the chip in the lower left hand corner gets really hot after <30 seconds of being on. Of course, I don't know if that's weird, because I didn't bother to open up the GBP until something went wrong.
Anyway. I was thinking maybe a fuse blew. Next to the Chip That Gets Hot, as it shall henceforth be known, is a component labeled "F1" on the circuit board. I reasoned that must be the fuse, but I have a problem. It looks like a PICO fuse, but it's only got 3 bands on it: gold, black, and brown. I have no idea what the amperage is, and all the guides I've looked at are for 4-band PICO fuses.
Here are my questions: Is this likely a fuse problem at all? If so, is the F1 component actually the fuse I'm looking for? If so, what's the amperage? If it's not a fuse problem, what is the issue?
I can post pictures as needed.
