se/30

I just grabbed another se/30. Pulled board, out in different chassis, works perfectly besides needing a clean and recap. No battery explosion thankfully. The other chassis powers up but screen stays black. Tried adjusting the brightness, nothing. It still boots, just screen stays black. Is this a bad crt or possibly just an analog needing recapping as well as PSU? I do have a spare analog I might try with the crt to rule out bad crt.

Reflow the yoke connector solder joints on the analog board

Well, logic board is recapped.. cant believe how clean this one was. Even ue8 had zero corrosion on its legs..

Was this the SE/30 in Brantford by any chance?

No, got it from a gentleman in Edmonton.

If the screen is black even though the power supply unit is on and the cooling fan is spinning, there is a possibility that +4.7V or more power is not being supplied to the 5V terminal.

If you have a SONY CR-44 or AcBel power supply unit, you can adjust the voltage with the internal trimmer potentiometer.
