Hope our OP can figure this out or others can help. I've read about other players and it being a resistor? Search that up to see if it may be the same. Do all repairs at your own risk.

krbahr wrote: +5EV which is +5V is not switched and always on or "Ever" on. That goes to the front panel. When you press the power button on the front or ON on the remote the front panel sends the ON/OFF control signal back to the power supply to turn on the remaining power outputs to power the player. You need a schematic and a meter to see if the ON/OFF control signal is being sent from the front panel back to the power supply. If not being sent the problem is on the front panel board, if the signal is there then the issue would be in the power supply. Verify there is nothing in the remote control plug in the back and that can also prevent operation. Thanks. I think I understand the concept. It's a little beyond my capabilities to fix, but I'm willing to give it a try. Is +5EV the label of a component I am looking for on the schematic? I assume I need to check this with a multimeter (very carefully) with the power plugged in - correct?

Yes a multimeter - Must be careful around the PSU - high mains voltage!... SM for 780 is on the Lddb website...follow circuit diagrams. Ive had Capacitor C12 on PSU go...someone else had the same fault C12..not saying its the same fault for you - but worth noting. [CLD-D780] Won't power up - PCB re-cap (FIXED!)If not confident best and safest to get a tech to look at it!!

cplusplus wrote: This can be caused by failed capacitors on the front board. Thanks. I'll see if I can figure this out but I'm not a tech. If I can't figure it out, does anyone know a tech that repairs laserdisc players, possibly in Florida? It's a nice unit otherwise so I hate to send it to the landfill.
