I have had the the PSP GO since launch and it broke about 10 years ago not sure how long exact.The issue I am having is when I turn on the power the light goes green but no display or sound and about 10 to 15 seconds later the power will just shut off.I have tryd three things first I bought a new lcd screen and that didn't work next I bought a new battery that didn't work and recently I bought a new display ribbon cable and that didn't work ether I am not experienced in fixing things and not sure what's wrong with it but if anyone knows how to fix this knows I would be much appreciated for any help thank you!
