E193FPC : Monitor power light on, Monitor starts up and displays image for 1 second or less, goes black and stays black, If turned off and back on it will again display image and revert to black. Results are same when attached to other computers.

It's a bad inverter /power board

Here is a similar dell monitor with the exact same problem....

10-30-2007, 07:54 PM I have the same monitor and it had the same problem, I got it for $10 at a garage sale because they "didnt know if it worked or not" BS, they knew it was broke. But i accepted the challenge. There are four transistors on the power supply board detailed as Q759, Q760, Q739 and Q740. It is usually just two that go bad on these monitors, but instead of hassling with testing all four, I would recommend just replacing all four. Here are some replacement part numbers. I used NTE2524, same as NTE2525, and paid about $1.25 each.
and here are Sanyo parts (hard to obtain):
2sc5707 C5707
2sd1803
2sd1804

ECG2524

The transistors are rated at 60v 20w.

Just wanted to share my success story. Hope this info helps someone. I found my info on some other forums that i can't find right now.

If the monitor power light is green and doesn't go amber, it means that the monitor can receive the signal from your computer fine but the problem is the backlight could not hold on when in operation. if the monitor power light is green and turns amber that means that there is a problem with its video signal processor and is already busted. Either way, you need the problematic part replaced by the manufacturer. If the unit is still under warranty, you can have it serviced for free.
