My HP 4+ would turn on and off rapid fire when I would start it. I installed a new high voltage power supply and now display is dark and problem still not resolved. Anyone here know these printers good enough to suggest a fix.
To be honest i would recommend passing on the fix. it's a good printer but for the potential amount of money it will cost to fix it is almost certainly better to walk away and buy new.
