JV3-160SP DOA today....

When we got into the office this morning I pulled the roll of printed material off of the printer from last night and took it back to the post-production dept. I thought at that time that the boss had stopped by late in the evening and turned the printer off to save electricity. A bit later I needed to print something, and noticed that the printer was still "on"...

Both of the power switches are on and the 220v power was tested good by an electrician this morning.
When you push the power button nothing happens, nothing at all.
With just the rear power on, nothing happens at all either.

I think the only thing I've seen on at any time today is just one of the exhaust vent fans running real slowly....

I took the back off and both of the rectangular green fuses are both fine.

HELP! Our regular technician is on a vacation until late next week. (what good timing!)

It's most likely a blown main board. Disconnect the power supply from the main board and turn the machine on again. If the power supply fan turns on when the main board is disconnected, your main board is fried. If the power supply fan does not turn on, it could be a bad power supply.

Vander,
Can you give me more specific information?
I can't see any power supply fan like what you have in a regular computer.
I see all of the wires coming in and going through the relays, then routing out to the different areas, but no power supply fan...
My cell is 859-445-5092 if you can call!

WOW, thanks for the phone support!
I unplugged the connector you mentioned and plugged in the machine and turned it on.
I heard a faint buzzing but after leaving it on in that state for a few minutes I still haven't seen the power supply fan come on or any lights on the power supply.
I turned it off and plugged back in the mainboard and could not notice any change.
The only part of the machine still functioning is one of the exhaust fans; everything else is still dead.
The faint buzzing I was hearing could have just been the fan...

It ended up being both the power board AND the main board.
Our local tech had both used, so we saved a good deal against buying new parts!
