Ricoh 1060 w/ no display, door open & wrench light on.

[shrum1340]

I have a Ricoh 1060 with no LCD display when main power switch is turned on. Also the open door and wrench indicator pop on within seconds after turning on main power switch. I can't see a code. There is no type of drive attempt by the copier. Checked all the fuses (fu101 - fu111). Tried pulling out all trays, fuser,duplex, disconecting RADF and finisher to se if one was causing a short.
I'm leaning toward a LCD board or Main power board.

What do you think???

Customer was in the middle of a long run when it happened. If that helps.

Also checked upper and lower door switches to make sure everything was intact. (for the door open light)

Fuse 105 gives door open, and if you have checked that then I would lean towards the PSU.

Why don´t you do what Fridgemagnet told you it could be: if you´ve seen the fuses change the PSU, Power supply unit. that you call Main power board

If you switch on/off the copier and it does not initialize, than replace P.S.U.

I got rerouted today and didn't make it out to the machine. Thanks to all who responded. I will update on Monday due to the holiday weekend.

Also could be NV ram.....A dirty corona makes discharges, or leaks that damages the nv ram....

It was the Main Power Board.
