Bad CCFL lamps, and I had purchased a set form CCFL Warehouse .com. but
I tested the lamps on a known good working monitor testing unit, which worked perfectly until i connected the lamps with the two bulb connector, one bulb would work ok on the unit with only one new bulb, and the others were the originals.
I purchased originally the 2.6 mm X 470 mm. bulbs, which did almost the same shuttdown on the good 2185W monitor test unit. Re-orderd a custom built bulb, 2.4 mm. X 467 mm. which actually made the shutdown quicker and one of the bulbs was not at full illumination on the small wire end about from the 2” to 6 inch area, but did lite the last few inches , then shut down the unit after about 2 seconds.
