Hi,

I have a Cold Cathode kit in my PC. I very rarely use it, usually its on for the first 2 weeks after an upgrade until the novelty wears off.

I've noticed that most of the time when I power it on or off from the switch, I lose video output to my monitors. The PC remains on (Though once it did power off), and I can still hear music, teamspeak, but there is no video output until I hit reset.

It looks to be connected properly. Any ideas?
 
Should only be a few watts - 10W at most I'd have thought.

The other option is that the inverter is doing something dirty to the rest of your power supply, interefering with the output of your graphics card.

CCFL inverters can kick out lots of EMI if they're cheap and nasty and not properly shielded...

This is because they generate 500V+ and usually switch at quite a high frequency.

You could try wrapping some tin foil around the inverter and CCFL cables, but it'll probably be too thin.
 
I would say your case is earthing somehow and sending a signal down the VGA/DVI cable cutting the signal.
 
Sounds like you have a case short with in turn is then connecting to the VGA or DVI plug. This will cause your monitor to power off.. Check the earths.

This may help.
 
Nope :(

Had the set out of the case and plugged into a molex as I had suspected the switch wsa touching the case perhaps but it still does the same thing - switch on or off and poof, graphics card powers down.

:(

Doesnt seem like you can get blue cathodes anymore either. Doh!
 
I'd give you some blues if your willing to pay P+P. my friend got me a kit with 2 lots in and i only needed the one set...
