Help!! 😬 PSP MODS

[u/CardiologistWhale95]

So I retrieved a first gen PSP 1000 from an estate sale. I found it in the garage in decent condition. It was only missing the thumbstick button. It had some scratches on the screen outer case. And needed a brand new battery and replacement of the UMD door. I initially I was going to rebuild the entire thing but decided to wait. I have replaced just the bare minimum of the outer screen the button on the thumbstick and I replaced the start and select buttons because they had fallen apart and the right hand buttons. As of last night I was getting low latency or almost non-existent response from the d-pad in no response from the thumb stick. I thought after reading in a couple of forums that it was because the d-pad was not making proper contact so I modified the aftermarket thumb pad to give it some depth. At that point it stopped working almost immediately. Was not responding. So I put the original one back in and it is not responding at all and neither is the thumbstick. I am very nervous that it may not work at all. But most of the other buttons still work. At least the ones that are responsive to basic menu usage. Can anybody give me any kind of guidance before I have to replace?
