PSP GO fuse locations.
« on: September 03, 2011, 05:10:34 PM »
ok so some1 asked me to fix their dead psp
no charge light or power up
so i set about the motherboard as i know sony like to put fuses on these sukkers.
i removed all of the shielding as to find the fuses and what coudl possibly be fuses.

i hope some1 can verify what fuses are for what.

ive marked the pics and will put voltage references.
please note this is a faulty board (NO POWER)


pic1

ok in the above pic we have pin1 of the battery port, with my charger plugged into the board i get a pulsing of 4.35 volts to this pin which i believe is correct. with the battery plugged in its a constant 4.20v.

point1 could be a zero ohms resistor and i get 4.2v either side.


pic2

the above pic has 2 distinct points and are both fuses i believe and both marked with the letter "L"
point 1 is a 1A fuse marked F7001 1A
point 2 is a 1A fuse marked F7002 1A
point 2 i get 5.23 volts either side so i think this fuse is OK
point 1 i get 0 volts either side !!!!!!!!!!!!! < i believe replacing this fuse will do anything for the PSP as there is no voltage either side !!!!


pic3

the above pic has 2 distinct points 1  a fuse and the other im not too sure about !
point 1 being a 1A fuse marked with the letter "L"
point 1 being a 1A fuse marked as F4001
point 2 im not sure about
point 1 "L" i get 5.23 volts either side. - OK

pic4

the above pic has 2 distinct fuses.
point 1 is a 0.5A fuse marked with the letter "F"
point 2 is a 2.5A fuse marked with the letter "T"
point 1 "F" i get 5.23 volts either side - OK
point 2 "T" i get 5.23 volts either side - OK


ok so these are my findings, i did this cos i cannot find anything anywhere about this TA-091 motherboard and its fuses
please note most of fuses are hidden under the shielding.

if you have had any findings please post up so people can learn from this.

i know the GO has been out a while but i just thougth it may help us at some point.

thanks

ps i think my fault is with pic 2 point 1 and the surrounding area as no voltage to either side of the fuse gets me thinking !!!!
also checking the switch i believe that too is working fine.

the fuses for the power and audio are on the other side of the board and are located near the bluetooth and wifi moduels if im not mistaken.

Yeah i remember that lol.

So im gunna say that the fuse on the other side is for the screen backight like all the other psp models. so the one near the battery is your best bet plus their's not much you can hurt if it dosent work right?

good idea mate.

im still looking at teh fuse on mine with no power either side of it.
somethgin else must be blown for that to happen right.

dave

EDIT:

if any1 has one of these machines apart at moment can they do a voltage check at either side of teh fuse im having problems with pls n drop down the voltages.

thanks
