PSP-3000 (TA-095) Display Issue – Backlight Works, No Video

Hey everyone, I need some advice on fixing a PSP-3000 (TA-095 motherboard).

I recently bought a PSP-3000 for repair. The original display was broken, and it wasn’t clear whether the video output worked, but the console played the boot sound and the buttons responded.

I ordered two replacement displays from AliExpress (one cheaper, one more expensive), both advertised as compatible with the PSP-3000 series and TA-095 boards. On both screens, the backlight works but there’s no video output at all.

At first, I suspected a faulty video chip, but the PSP outputs video to a TV via cable just fine.

Has anyone experienced this issue before? Could it still be a motherboard problem, or is it more likely the AliExpress screens are just poor quality? Any advice on what to check or where to get a proper replacement would be greatly appreciated.

TL;DR: PSP-3000 TA-095, boots fine, outputs video to TV, but two AliExpress replacement screens (backlight only, no video)
