we got kyocera wide format 3650w month ago, yesterday it stop working, and nothing on screen show on, except the power looks on, cannot print, scan or copy, we cannot do or see anything on the screen, we checked the screen cables and connecters nothing wrong, any idea?

Could be the Power supply for the controller.

I agree with billyzoom. Especially in the early runs before they updated to better power supplies, this was certain to happen sooner or later on a 3650w. It is simply an SATA ATX PC power supply, but I don't remember the power specs since we have not had to change one for many months now.

Also, there is an auxillary power supply board just to the right of the controller, when looking from the rear of the machine. IF the fuse on this small board opens, the display will be blank. Most often the internal Power supply in the controller is the problem. Just take the core to your nearest computer store, and ask them for a replacement off the shelf.

Thanks guys,we replaced a burnt smelling power supply and the machine still had a blank control panel.the small fuse on the board to the right was blown.I don't think we would have ever found that.Also KMA wanted $700 for the power supply.We took it out a junk computer for free.thanks again for your help!!

We have one just like this. One of my guys tryied to put on a power supply from a PC and said it would not fit. Was there something you had to do to the power supply to make it fit?

I wish I could charge my customers 1000% markup and still sleep at night. $700 for what is at most a $70 power supply, OMG.

Had one like this not to long ago, luckily it was in a Staples store so Kyo supplied everything. Found the blown fuse, was able to find a suitable replacement and the local Radio Shack, still no display. Kyo recommended the power supply, still nothing. I basically replaced the entire controller, which is a simple PC motherboard with a CPU, Memory and a HDD drive, but since there is no part # for it as a whole, you must replace it piece by piece. I'm not sure which specific component was the faulty one since I replaced them all and the machine came back to life, no sense swappin things around at that point. One thing I noted was lotta dust build up in the CPU cooler fins and the air inlet vents to this area where pretty restricted. Just like any old PC, cooling air is good.

Mark, you have to cut a portion of the housing frame, not the power supply box itself.The power switch and the power plug are opposite from the org.power supply box.
Took some cutter pliers and took a small section of the frame out. Then it will go in perfectly.You just need two screws to hold it.

I found a replacement, a few years ago, on the self at a Staples that was an exact fit (better wattage). Didn't even have to leave the store.
