does anyone know how to fix a ps3

Their are reasons game console's may not work.

1. If আপনি left it on too long while doing something else then আপনি caused it to overheat.

2. If it's been tampered with then there's something wrong with the wiring from the inside.

3. If আপনি অথবা you're বন্ধু have smashed it অথবা tried to then the entire thing is screwed up.

আপনি might have to buy a new one if it's any of these problems, sorry.
