I’m trying to repair my PSP 3001 from a broken LCD screen. I purchased a new one and replaced but still wouldn’t show display or sound. So I purchased another motherboard switching the original TA-090 to TA-095. I am now able to hear sound but still shows no display. I’ve tried doing the reset screen using the home, select, square, triangle buttons but still nothing. I’ve also checked the backlight fuses and they put out continuity. Can someone help me continue troubleshooting since I’m out of ideas for now? Any additional help methods would be much appreciated
