    - HP L1506 LCD goes black after several hours and stays black until power plug is removed and reinserted. Now LCD goes black within 10 seconds after power is applied. Sometimes front panel green LED flashes like a heartbeat (defective electronics?) Unit was Manufactured July 2006.
    - VGA cable exchanged with known good cable with no effect.
    - Unable to call up OSD menu before unit goes black (LAMP issue?).

Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.

The problem lies within the DVi or VGA cable. If you bump the cable, or if it is not securly in place at one end, or the pins are broken, the picture won't be displayed correctly, Check to make srue both ends ae intact and plugged in securely, and if it still happens, buy a new DVI/VGA cable . That will solve the problem. It also explains why the light stays on. There is an external power source(the wall outlet) powering the moniter, but the video cable is not working and isn't transmitting the picture.

Power light blinks red, green and off. No picture

Is there another monitor input on the back of you computer? Sometimes this happens when your graphics card is not compatible so it is best to try another one. If you have another one plug it in there first. If you don't try the monitor on a friends computer. If it still does the same thing, it may be a manufacturer defect and may need repair.

Dell LCD Monor light keeps blinking green, screen is black cannot stop blinking unless unplugged from power source but upon plugging back in monitor starts blinking green again

Hello,
Your monitor has a bad power supply board. This happens often on LCD monitors because of the heat buildup in them. If you can solder them go to our web site at:
www.ccl-la.com/badcaps.htm We have a step by step dis-assembly and repair guide for your monitor. There are several versions of the E173FP some end in b , f, or c so be sure to check your monitor.

I hope this helps, if so please rate my solution.
