Many times when I power on my Emu II+HD the top row of the LCD is solid blocks, but the machine proceeds to boot OK (just no display). If I power cycle the instrument, it then displays correctly. However, it sometimes takes 2 or 3 power cycles to restore the proper display, and it does not seem to matter if the machine is cold or hot.

Is this most likely a failing IC in the display circuitry, CPU RAM, Boot or Scanner ROMs, or something else?

Any tips would be appreciated.

Thanks!

Sounds like the PSU. Check voltages and look for burned/discoloured power connectors.
