I Restored This Yellowed & Broken PSone - Retro Playstation Console Restoration

I will restore this PSone console. It is an updated version of the original Playstation. It was released almost exactly 20 years ago.
The console is very yellow and and dirty. And it won't read the discs. It gives no picture out which it should do when the there is an issue with reading the disc only.
