Welcome,
If you want to get the color back on most modern plastics there is a formula of common household chemistry that does the job...
Search Google: [How to get the color back on ABS plastic]
I searched your other YouTube posts to see what else your doing... Interesting...
Electronics has a finite life because of mostly capacitor deterioration. Basically, after 5 years, depending more or less on the price-point of the product, the capacitors are beginning to fail or have. Surely this has been seen in computer mother boards and displays. But, it happens to all electronic products using electrolytic capacitors.
Capacitors will degrade performance by electrically leaking and shifting voltage values on active devices to the point where there is distortion, noise or failure.
One point to stress is that wholesale change-out of capacitors should not be undertaken without some consideration overall. Occasionally a device will refuse to work because the wrong caps or poor work was done.
I see in the vid that you may have the Sam's for one of the phonos, good. That is a start at least for the phono that does not sound well.
I understand that the end run of phonos have become more collectible but much more so being placed into use. There is some support out there for VM turntables as well as folks "rebuilding" the phono drive idler wheels and the reproduction cartridges. All can be found with a Google Search. If not Google. then Duck Duck Go...
YMMV
