PSone screen fuse

[project_failure]

I need to jump the fuse on the psone. Do I have to remove it or can I just put a blob of solder over the whole thing?

blob solder works fine.

Thanks I greatly appreciate it.

As I recall, if you bypass the fuse, power the system on 5v or you will fry the board.

A while back, I bought a screen very cheaply as it didn't work, opened it up, the fuse had blown. I shorted the fuse, powered the screen with 7.4v and I got smoke and a couple of components started to crackle and split apart. Just making you aware!!

Thanks for the tip. I guess I will try 5v first and if nothing try going up.

Yeah but you should be fine, what did you do to blow the fuse anyways?

The reason bacteria blew up his screen is probably because whatever caused a short and blew the fuse in the first place was never fixed.


To be safe you either need to replace the fuse and see if it blows again, or use a current-limited bench power supply so the pcb won't fry itself.

I think I forgot to ground the screen before giving it power or something.
