dual cathodes not working..

toon_mad · 8 Apr 2009 at 15:18

hi so i bought a set of 12" cold dual cathodes last week, tried setting them up but they didnt work. I thought it was because one was faulty, had a slight crack in it, got the replacement sent out today, no cracks or anything in the tubes, still doesnt work.

This is how ive fitted it, dual inverter is connected to psu cable (the cable cannot be faulty because it also power 2x 80mm fans through the same one).

hooked up each cathode to the dual inverter and powered on the pc, no neons.

There are both a male and female molex connector, BOTH dont need connecting, surely the one will do right?

PS, PSU should be enough if you see in my sig.

Cheers

just tried connecting with both male and female, still nothing. i was told they were tested before sent out, but they are not working.

I cant see that ive connected them wrongly,

2x cathode connected to --< 1x inverter --> 2 molex connected to psu

power pc on, no snazzy lights :confused:

You only need male or female, and either will work. Maybe check the tubes aren't bust - see if they rattle (broken filament) and check the wire connectors going to the inverter and those in the molex (slipped pin) - they can work loose.

tried in 3 different molex connections, looked close at the cathodes - non look cracked, ive shaked them carefully and hear no noise, dual inverter looks fine, as flimsy as it seems.

what else is there to try, that covers it all really.

i hate these neons, this is the 3rd one ive tried in 6mths and none ever work :eek:

There is a power switch for them, try turning them on.

already did, but nothing, ive even tried using the dual inverter from the other, its just not happening, i have sat here 4 green cathodes and 2 dual inverters, nothings working.
