PSP PHAT Green light only after repair (NOT BRICKED)

[FULL32GB]

Hi. I changed my PSP LCD because it has dead pixels. now during the process, when removing the LCD from the motherboard the lock (THIS: look at #3
that lock or clip right there snapped off and my psp would start but wont show any display. so I had it repaired. don't know how it was repaired, but a new lock or clip was put in the motherboard's lcd slot. but now I have a new problem. my psp would start but it only shows a green light for about 30 seconds then it turns off again. when I try to start it up again there would be times that it would actually start, then It'd go to the xmb and I can play games, but when I go to the VSH menu it would freeze, and it won't start up again, it'll just show a green light. I tried gend-3, prometheus, 5.00m33, all show the same results.. it would just show the green light and it would sometimes start. I need help..

maybe it's an incorrectly installed lcd
