Mobo fryed? hmm...

[crashman2k7]

so i was working on completing my full out moded psp and the music was playing so i wanted to add sum red led to the UMD DOOR so i tried using a 20 ohm resistor on the positive connection of the LM386 chip ( positive out)(sound reactive mod)
and well

all i hear was the music becoming distorted and the psp turned off
so i tripped it down to the board, battery and power switch.
The light turn on and turn right back off

hmmm does it mean i burnt the mobo?

if it sound like that
ill be posting in the action room for a mobo =)( if anyone reading i need a whole wifi/mobo or mobo compatable with ta-079 parts

um.. 1st of all lol nvr solder while psp on
2nd, u tried to turn psp on and it didnt work? i didnt understand wut u said, you shouldnt give up on the mobo so fast lol, try to bridge the fuse at the top right above the little white connecter thingy for the ac plug. just pt a dap of solder over it and if the mobo was fryed maybe that will help it

[crashman2k7]

LOL i never solder when the psp is on! there is sum what of current going tthrew the iron(i figure when the led would turn on with no other source of power*

1. The fuse has been bridge b4>.> it blew because of a bad battery(gay ass after market battery)
2. it was working perfectly for a little whiel(had blue led and red LEDs with a 10ohm resistor on it)
3. i switch the 10 ohm to a 100ohm to see if the red LED would react better to the sound)
4. the psp speaker made a buzzing noise and turn off
5. now when u turn it on my power indicator turn on and turn right off
6. i packed it all up and put it in a lil box and toke a long ass walk =)

hmm.. well it shound not have fried unless you did something rly rly wrong. sounds like ur psp is bricked, maybe something in flash0 got fried xD

[glenng82]

still loads games just no sound

[TaSlAyEr]

maybe he blow out something were the speakers plug into cuz it to turn off as soon as you turn it on

[crashman2k7]

pretty sure i didn't do nutting wrong,
 
if it was brick id be able to pandorize it but it just keep turning on and off the power indicator
yea am pretty sure , something along the 5v contact point or along the speaker got fried

a fried speaker fuse wouldn't stop me from turning on the psp would it?
the charger fuse is all ready been "fixed" by soldering the 2 point with each other
