Two sets with almost the same problem, the reset pin of the 5 pin 5v reg/reset IC has pulses instead of 5 volts. One set is on and won't turn off the other is off and won't turn on. I have replaced the L78MR05 IC Q840 and no help, no schematic for either set. Has anyone seen this problem? Would anyone have a PDF to share?
