If changing the Power Supply does not repair the problem, check for bad solder.
As the equipment gets older the solder drys out cracks in the shape of donuts
appear on the pads. Than as the pad warms up that donut separating the pin from
the pad preventing a connection.
Us a magnifying glass to see the donut. Add flux and reflow the solder.
Also it may be necessary to replace the colour ram or the VIC chip.

Yes, you can substitute a C64 power supply on the newer VICs.
