V30 Power 1 board replacement


Recommended Posts


SO I just replaced J340008-03 Power 1 board on my V30-RA machine and now I have no display and no motor is runing.

Looks like the heater fan kicks in and the chem level sensors are going back and fort due to low chem, so I toped them of and that is all ok 

Machine turns on and on the new board I do see LED's turning on and off but that is it.

Do I need to reinstal the software ?

The machine was working fine apart from Fix 1 and Fix 2 heater not working due to burnt SSR's #3 and #4, so I replaced the Power 1 board and now POOF, no display and no motor running.

I have also tried turning the machine on with the floppy disc inserted but got the same resaults, no screen and no drive motor runing.

Your help is sppreciated.

This is unlikely to be a software issue, this board contains no software.

Check you haven’t missed any connectors. J/P74 is for the display, J/P63 is for the drive motor, J/P62 is for the drive switch.

Make sure the jumper cables are the in the same position as the board you took off.
