Have you checked the internal battery for leakage?
Have you checked the power supply rails for the correct voltages?
Have you checked lose connectors inside (ribbon cables, reseating ICs if socketed -- make sure you donīt touch them without having grounded yourself first, they hate static electricity)?

Just some ideas.

40 US$ is a decent price. Unfortunately, any type of service documentation for these Kawais is a bit difficult to come by.

Do you know the Analogue Heaven mailinglist? This is the place to be for all things analogue and "vintage".

Based on the age I would say its a power supply issue. The capacitors have problem dried up and need to be replaced. It should be a pretty easy fix that just about any tech can do.
Take care.

Well, never got her fixed.
BUT a young tek head just gave me $400 bucks for it and drove 2 1/2 hours to get here!.....and yes he knew.
Hes a 20 year old tech kid, has arp 2600, jupiter 8, junos,  and such, he fixes them, only buys analog.
