PSP 3000 LCD replacement help?


I’m replacing my PSP 3000’s screen, but I get no display. I’ve been examining the screen and connectors, and it seems one cable won’t stay in (not the big ribbon, the small one). The locking tab of the connector seems to do nothing. When looking at the cable, half of the silver bit is in - right up until the small indentation. The rest of it is out of the connector.

Do I just need to push it in more? It feels like it’s in as far as it goes. Would you suggest I just tape it down with motherboard-friendly tape?
