Is that (4th) pin, the yellow one, supposed to be 0v?
I don't know. The legend is obscured in the picture.

I'll try another cable. I'll grab a new one from work. Maybe I have two bad ones and my other source isn't as sensative. I'll take a better picture of the molecular connector later.
That reminds me of another thread. Try to get a quality thick shielded cable. One person has those cheap thin cables and when he replaced it, the problem went away. Unfortunately, I don't remember which thread it was or what the original symptoms were.

Well I hate to admit this but I guess it will be good for the forum. The problem was the cable. I tried a brand new one and it works fine now. I tried the old one on another set up and it is fine too. I guess this monitor is just a little more sensitive than others. (and I have two "bad" cables).
Thanks for all your help.

Reason: Bad cables

After a lot of trial and error I have the CCFL lamps back on!
I won't keep you in suspense any longer... The problem was a blown fuse!
No... not the big white one, it was a little black one labeled PF751 (see previously posted photo if you're interested - it's on the right side and looks more like a rectifier diode).
I can read the letters "MS 2A" on it - so I guess that means that it's a 2 amp fuse. Someone else posted a schematic for a similar Diamond View monitor, which shows a 3 amp fuse. (ref: Inverter Schematic )
I've jumpered the fuse with an extremely fine strand of wire, and the CCFL now comes on. I'm giving it a burn-in-test right now. So far 1/2 hour and all is well.
I am, however, not willing to call it "fixed" yet - after all... Why did the fuse blow in the first place?
Sure... I plan on putting in a proper fuse, but I don't want to re-assemble it and have it blow another fuse (or worse) in a day or two.
But hey... after way too many hours on this project - at least I've got something positive!
Any thoughts?
Thanks man , you save me
i was thinking about buy another monitor
Repair kit arrived yesterday and after re-soldering all four Xformers (bent the leads out for better electrical / mechanical connection) and replacing two c5707 Xsistors it is back up and running. Will burn it in for a day, but so far so good.
Just wanted to say that everything is still working fine since the fix. Thanks again for the support!
Anyone having issues with this model should try adjusting the pot on the back of the panel. All fuses, caps, xr's all tested good for me so I tried adjusting the pot and sure enough I went from a screen that would turn on for a moment then go black to a monitor with a screen that stays on. Remember small turns on the pot and I recommend doing it while powered up so you can see changes live.
