Re: CMV CT-934D won't power on - secondary voltages disappear
I got this monitor for free from the local ad. If I had another one identical monitor, yes, I would have tried swapping boards.
Funny, I was thinking about a test like this for the last couple of weeks and what I have at home to do this.
Thanks for the idea, I'll see what I can do to test this in the next few days.

Set up the PSU/Inverter ONLY..ie NO Logic PCB,Plug in the CCFL's,and on the connector which normally goes to the Logic PCB,apply Approx 3volts DC(from an external battery perhaps),between the ON/OFF pin and Ground.This will light the Lamps.HOWEVER I had lying around a little PC Fan,a Standard 12v,250Ma one,and a little experimenting showed that applying 12v to it, it actually took 62Ma,BUT applying
5V to it the current increased to approx 160Ma,So with the Set up as above,if you have a Fan,or similar, put it on the same connector between the 5v pin and Ground.The question is DO the CCFL's light ???and the Fan spin ???
