psp wont turn on - i have tried everything...

[Nemesis]

ok im getting a bit tired of this now, since a few days ago my psp turned on perfectly, left it off with the battery out and went to turn it on the next morning-nothing. i put the power plug and connected it, still wouldnt turn on, i swapped the ribbon with another and have tried three different powerboards with every combination i could think of-nothing still not turning on. i bridged the resistor by putting a big blob of solder on top, still nothing. took out the mobo, connected battery, power and powerboard to the mobo (in no case), again nothing!

when i put the battery in, there is dead silence but when i connect it to the power plug all i hear is high pitched noises around the motherboard area - no where near the powerboard.

please someone help as i feel tired of not being able to solve this problem

all help appreciated, thanks

Is there a short or is one of the silver lines scratched? (I can't remember what they are called lol) Or maybe you have a brick?

is it like a screeching noise? ahah do you have wires connected to the 5v and ground? try taking all the extra stuff you did to your psp off and turn it on maybe theres like a short or something. some kinda metal touching eachother

yep it is like that and i do have a wire connected to the 5v point, ill try it later then

i do have custom firmware but was working flawlessly, and have never bricked unless you can brick your psp without flashing.

btw admins and moderators, i have used search button and have tried everything menotioned in other topics but wasnt successful, so please dont lock

thanks

so howd it go? im pretty sure that all you need to do is solder to the 5v and ground a little  bit cleaner. last time this happened to me some solder was connected to the  golden part of the motherboard under the 5v and ground
