R2001C HVPS question
Posted: Thu Sep 22, 2016 6:36 am
Hey All,
I have a R2001C that I am doing some refurbs on it and came across an issue with the HVPS A10 module.
The HV Source voltage feeding J1 Pin 3 has a LM7812 inserted between the Pin 3 of the 8 pin dip and the orange wire of the ribbon cable.
This looks like a factory mod because there are two 12 Ohm flat packs mounted on top of the LM7812 wrapped in capton tape.
I have checked what few manuals that I could find and can not find this modification.
Also, I've noticed that the monitor will not power up at all without this module.
Does anybody know about this and do you have the print of this particular power supply?
Thanks
