where can I get help with PSP hardware problem?

I'm not sure where to ask this question. I'd appreciate it if someone could point me where I can get help fixing my son's PSP. The PSP was working fine until a game was removed and something seems that have broken and now it won't read the disks. It will boot up but you don't hear a motor running or anything.

My son looked at a friends and he says that when you open the disk door and look inside, there is a black lever on the left that when you push down on it, the glass eye that reads the disk glows. Nothing spends. It seems like a hardware issue.

I'm a DYI and have taken his PS2 apart many times to clean and would like to fix this.

Thanks for your help.
