Hi there,
Clearly your monitors are evil. Try turning them on at home and see how you fair out. :)

I'd suggest looking at the mainboard. I assume the blink is rapid? A slow on, followed by a short off and back on again is normal. The fast blink thing is a mainboard issue, and the absence of blink (or light) is power "supply dead."

There is a problem transistor on the mainboard that seems to be the problem most of the time. Replacing it takes about 5 minutes if you have the tools and the talent, and the parts cost under 3 bucks at Radio Shack. Just pick up a pack of NPN switching transistors and de-solder / solder your way to a working monitor. There's usually only one on the board, so it's easy to spot.

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

It is most likely that the filter capacitors on the power inverter board have failed. I took mine apart and found seven swollen capacitors on the this board, they fail prematurely and seem to be the only thing wrong with the unit. I replaced them and now it is working just fine.

six 470uf 25v electrolytic capacitors and one 220uf 25v Capacitor.

you should not attempt to repair this yourself unless you have some electronics training since there is a shock hazzard involved and also these capacitors will blow apart if they are installed incorrectly (very messy experience).

Should have clarified I have a Mag lcd LT916s and need a backlight bulb.
