Broken Psone

Guest · Post by **Guest** » Mon Feb 28, 2005 12:25 pm

Hello, I had a Psone...it worked...i took off the cover and took out the circuit board and it now dosnt work....any ideas of what may have happened? I was very careful with taking it apart..maybe...static electricity? If that is the cause i could punch myself for not buying one of those static electricity bracelets from radio shack. If I plug the power cord directly into the psone...it dosn't work at all...no power...if i plug the power cord into the lcd (when the lcd is not connected to the psone) i get power to the lcd. If i plug the lcd into the psone and plug the power cord into the lcd i get power in neither. I tried putting it back together...still dosn't work. Any help would be greatly appreciated. Thanks!

humm...I just read riva16's post about reviving his broken psone by shorting the fuses....what exactly do you mean by shorting the fuses? And do have a picture of the fuses so I can know what im looking for? BTW the post above this was my post...I just registered my username...figured I better have some better way to identify my self then "Guest"

Thanks!

you take both metal contats and connect them together.

Ok. Sounds easy. Now how do I locate the fuses. And also, that metal/aluminum sheet that goes on the bottom of the motherboard...is that just to collect heat? Or is it actually needed to make it run.

Thanks!

to collect heat. Let me see if I can snap a pic.

WAHOOOOOO! It works! Don't worry about the pic man...i found one in the forums....THANKS SO MUCH. I jumped the fuse labeled ps600 and the green light lit up! Now...does anyone know what the specs/ratings on the fuse are...i would rather replace it then jump it...Again thanks!

Thats the sad truth about surface mounting componiance is that you really can replace them. Try and be more careful in the future so that doesnt happen.

Thats better...

But really you could, but its a pain to solder anything that small.

Now hurry and get the fuse replaced before it overloads again. ^^*

It should be fine without a fuse since im using 6 1.2v AA batteries right? It will only get 7.2 volts and it will only draw the amps that it needs. Oh...and that reminds me...what will the output voltage and mah be on a powersource wired like this: http://programsandprojects.tripod.com/id20.html
Basically, I want to get 7.2 volts out of 8 1.2 volt 2200mah (or 2500mah)batteries. 6 of them give me 7.2 volts and I want the extra 2 to only count for extra mah. Should I wire 5 in sequence then 3 in parallel and wire the ones in sequqnce to the ones in parallel? Im not exactly sure how you calculate the output voltage and mah with sequential and parallel wired together.

That looks a little dangerous, what you want to do to get 7.2v is have a series circuit set up. Just have all the batteries connected negative to positive. The way you have it drawn out your mixing voltages and its not good to do that.

Still, something caused enough power to blow the fuse before. If it happens again, youre PS1 wil be destroyed unless you get a new fuse. Jumping a fuse should only be a temporary solution. I remember someone else had the same problem, and they left the fuse jumped and quickly fried their PS1 completely.

where can i get a new fuse?

Well, I'd have a meter on it and play it for a while. I mean bot up, seeking, and the whole nine yards. Then I'd take the highest current, add less than half an amp, and search for a generic fuse for it at about 7.5V(unless the PS1 has a 7805, then use a 5V fuse).

by meter you mean lika an OHM meter?
