On Q851 you should have -31V (ish) on the input -6.8V on the gnd pin and -24V on the output pin.
Your problem is in that area by the looks of things. D851 should have -21V one side and -31v the other.

Voltage at D851 is very low -o.4v at both side. Could it be the transformer?

The player is ok, It's only no display. Ac at c854 & gdn 14.3v. Between u107 u108 3.3v

Problem solved, it's c854.resolder & display is on again but seem blur so replaced it. THANK YOU VERY MUCH BRENT!

I've still not got round to actually doing anything to my CD63. I'd procrastinate if I could be bothered.
As part of my initial plan, I was looking fit some regs, and was looking to use peranders SSR design and make some boards myself (though may cop out and order some boards from him instead).
What voltages do I actually need to supply?
Looking through the schematics, it seems to be mostly 5V with +/- 12V on the output stage. Though I'm not sure on the clocks. I was looking to take Ray's Kwak variant and change the power supply to be a superreg design but note it uses an 8V reg, so am unsure what supply I need to use.

Where do i feed the out put of the new reg to what resistor on the rf hf and decoder??? Translation needed please
