Need Help Mutoh 1204 Not Powering Up

I have a Mutoh 1204 that has been working fine until I went to turn it on today to print a job. The Data light flashed one 1 time when I tried to turn it on but that is it. When I pushed the power button off and on a second time I do not even get the data light to flash.

I looked at other post for answers and tried unplugging the power cord from the machine and resetting the memory but neither one helped. The 2 fuses on the power line and the one I can see on the power supply board are good.

Any help would be appreciated.

 

Where is the contactor located? I have 120V up to the power supply board.

 

I Just tried moving the ribbon cable around and it did not work. When plugged it back in this morning and tried to turn it on the Data light did flash once but does not do it again after the first try.

Are there any test points to check the voltage to narrow down the problem to a particular board such as the power supply or the control panel? I can probably swing a new power supply or main board but don't have the funds to start swapping them out without being able to narrow it down.
