Mac Plus - Horrible horizontal lines

[macsonny]

Hi All,

Recapped Mac Plus giving attached screen shot on boot. Not sure what to do with this? Anya advice?

Thanks

Sonny

Is there a bong when the plus boots? If not, then it may be a problem with the ROM.

CRT scan line, this is present when voltage is too high or brightness out of specs..

What are the voltages ?
