Quoted from teekee:I have a SP that plays 100% but has no display. I had the acid damage CPU repaired by Clive. I changed ribbon cables and I tried different displays. I seem to have the 5v and 20plus volts to the display. I guess my problem lies at the display board itself? Anything else to try or check?
Check all the voltages at the display. Should be +5v, +12v, +68v, -98v, -110v. You can measure them all on CN2 of the power supply board. Page 81 of the manual to see which pin has which voltage.
