Mutoh Rockhopper II 64" - All leds are blinking!! HELP!!

[orfeo25]

HI there

I own a Mutoh Rockhopper II, and since the thursday of the pass week i had an error, specifically Error 103 Fuse 2.
I mentioned the problem to my service tech, and they told me is a problem of one fuse in the motherboard, those who are black, small, with a number 50 in the top (look the pic). The technician, told me that are fuses of 2 amp, and are located near the connections of the printer-heads. With a tester I could check which of these fuses were gone.
I founded 2 of theses fuses that weren't working (chekecd with a tester), so I bought 2 fuses of these kind, and changed the olds for the new ones.

NOW, after welding the fuses to the motherboard, check that are ok, and reconstructed the machine, I turn on the machine and happen this:
1) the plotter hangs in boot
2) all the leds of the control panel are blinking
3) i can't turn off the plotter, the only way is unplug the power.

I'm waiting the verdict of the service tech, but these guy take their time...

What i did wrong? the fuses are well welded, and i didn't touch anything in the motherboard.
Could be a printhead burned that cause some kind of short circuit?
A problem with the head board?
The motherboard is gone?
Please HELP!!

Ps. sorry for my english, i'm from spain and google traductor doesn't know some technical terms...

It may be difficutl to diagnose what caused the fuses to burn in the first place.

That may still be the cause of your issues.

I just talked with the tech service, and they told me that is a problem in the motherboard (where exactly, they didn't know...).

So, anyone knows someone who's selling a motherboard for a Rockhopper 2 64"? or some web that sell mutoh's motherboards at good prices?

I'm wating the answer of mutoh europe, about the cost of the board...

sigh...

Sorry to hear of your troubles. I have not done any business with these people, but i have come accross their website in the past. Here is a link to a page that shows mainboard for your printer ant the bottom of the page. Might be worth checking out.

i would check for any solder bridges. If you replaced those fuses and welded them in with solder.
Also, wash off the solder flux. This stuff will cause an electrical leak too.
