I just did this mod yesterday from 4:30 to around 12:00. It took me forever to fix all the shorts. Wrap the LM386 chip in electric tape. Put electric tape over all the wires showing. Make sure the wire isnt touching the LCD cage and metal thing under motherboard and make sure u soldered everthing correctly and check if any wires disconnected by itself.

I have tested all my fuse : power, usb, LCD and they are not blown

so I think I must change my motherboard

No, make sure none of the wires are exposed, isolate your speakers (srsly, happened for me that one of them shorted when the LCD cage was on) and make sure there isn't too much pressure on the wires. Also insert your Battery, and get really close to your PSP, if you hear a clicking noise, it's a short.

I have disconnected my mod

and when I start my psp the green LED of power lights one second

I have same problem. After removing my mod, the green light flashes once then psp shuts off. The power fuse might be blown but where is it???

budgray19 · « **Reply #14 on:** January 21, 2008, 11:05:08 AM »

well my 2 cents is to solder off teh fuse and just put a nice glop of solder on it and if it dosnt work then its something else
i did the smae with my lcd backlight
lol but thats what i would do

phoenix3200 · « **Reply #15 on:** January 21, 2008, 01:35:49 PM »

I tried it again and I am sure it is not blown !

do you have an other idea ?

phoenix3200 · « **Reply #16 on:** January 23, 2008, 10:37:31 AM »

What should I do?

lookkool3 · « **Reply #17 on:** February 20, 2008, 09:24:47 AM »

where did you get the mod parts from?

cwn723 · « **Reply #18 on:** February 20, 2008, 08:44:43 PM »

How do you bright a fuse? And what does bridging it mean/do

smoke comes from the lm386 if any wires or pins cross but the same goes for if you bridge a fuse then any wires cross,which is not a good thing........it may look cool but its not a sight worth 100$
and i22foosh you are really starting to get on ppls nerves with ur constant stupid spamming,check the wiki and shutup,it was also explained twice in this thread,stop spamming or you will get banned

phoenix3200 · « **Reply #21 on:** July 04, 2008, 07:53:19 AM »

I get the MOD from http://www.pspgen.com/modules.php?name=News&file=article&sid=3990
i have not seen smoke

rceckspurt13 · « **Reply #22 on:** July 04, 2008, 12:51:38 PM »

so it still dosent work even after you removed the mod? Closing the psp likely put pressure on somthing and caused the short. I would try getting a new powerboard first. They are much cheaper then motherboards and if it still dosent work then you have an xtra powerboard.

phoenix3200 · « **Reply #23 on:** July 05, 2008, 12:30:23 AM »

it still doesnt work even after I removed the mod
and i dont want to buy an other motherboard

because I have bought an other psp and i succes install the mod and succes close psp and i is very fine

but i want to repair my first psp if it is possible ...

you could have static-zapped the CPU. if this happened, you will need to get a new mobo, but you most likely shocked one of the smaller, cheaper parts that the power goes through.
