My PSP 3004 wont't boot unless pressure is applied on AV plug
I bought a used PSP. The problem is when it came it did not wont to boot up unless I press on the plug where the AV cable is being plugged in.
I replace the existing LCD but that did not change a thing. Namely, After I apply a considerable pressure on the av plug (black plug on the left side) with my thumb and forefinger from above, it boots up fine. Sometimes if pressure is not significant it boots up but with no screen lid up, only sound is heard when directional buttons are depressed.
If I turn it off and start normally it just show green power light and nothing more. Than I have to keep up the power button for like 15-20 sec before it turns off.
The console is not bricked, but it seems like some bad fuse. I never tried to take it completely apart except changing the LCD and PCB switch, so minor repairs. Never took it completely appart.
Does some one know is there some schematics or diagram of the PSP to know how to disassemble it and put it back together, so I can try to pinpoint the problem.
Is dit een goede vraag?
