JV3-75 No Display -- Power on, green power light on

[Mimaki Mama]

I just changed the black print-head this morning. I powered up, the printer was going through its warmups (galloping horse & wiping) then the display just shut off. Now, nothing.

The green power button is illuminated. But the display screen and small green light next to the display screen are both out.

I powered down, unplugged and waited 10 minutes... plugged in, turned on, and the display light flashed on for a 1/2 second, but NO fans, no power, no backlight on display.

Currently unplugged and waiting for tech to call or one of you pros to help me out...

I opened the back, disconnected the power supply from the main board, plugged in and fan went on. I'm guessing this means it is the mother board then.
Does anyone have any ideas?

That would sound like the main board has failed in most cases. Before you go spending money on a board I would disconnect the print head cables and turn the machine on. If the machine turns on, I would get new print head cables or try installing them again. If the print head cables are bad or not plugged in perfectly, the machine will turn on like you are experiencing. Give me a call if you need any parts. 303-733-6671

I reconnected the power supply to the main board, and DISCONNECTED all of the head cable on the carriage assembly. Still nothing. I though this would at least boot up with 08 head errors across the board.

I guess it's the main board.

I have fixed one thing after another with this machine over the past 3 weeks.

I really need a tech in the Cleveland Ohio region. anyone?

I don't know any techs in the Cleveland, OH area but I'd suggest calling Brian at Pioneer Supply Company in Pittsburgh, PA; about 2 hours travel away. I've worked with for years and he does good work.

In any case, yes, it does sound like the Motherboard is the issue, unfortunately
