Dell flat screen

Is the computer plugged in to a known good power source with a known good power cord? Also, make sure the power is fully seated on both ends. When you press the power button are you getting any indicator lights? The power button itself has an LED that will be either solid green, blinking green, solid amber, blinking amber, or off. Do you hear any beeps?

I think you might have the same problem I did with my E178FPb. I made a video on how I fixed it.

the only thing you can do, is to get a qualified service technician if you are not an electronic expert. because the problem is in your power supply and inverter board. due to heat pressure inside can damage components specially capacitors.

Hello,

We have a dis-assebly and repair guide posted on our web site at:
www.ccl-la.com/monitor_repair.htm
The problem is usually the driver transistors, our guide shows where they are and what to replace to get your monitor back running again.

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

just try running the Test on the monitor(monitor self test) ie disconnecting the video cable of the monitor & leaving the power cable connected & then see if u r getting the red,blue,green multicoloured bard moving on the screen or not,if yes then the monitor is fine otherwise the monitor is bad.

Depending on when you bought it. There should be at least a one year warranty. If its still under warranty have dell replace it.

some transistors on the board have shorted they supply power to the inverter to run the lamps, they power is not cut off intermittently and the protection circuit has stopped the monitor. the fix is here

goo dluck if you want it fixed for you let me know

How many red and green blinks to you see? (What pattern?)

That sounds like the backlight inverter board. Check ebay for the board or a repair kit for it.

My power button was also blinking orange/green/orange/green. I pulled the battery and put it in the back of the cradel. It still blinked there too, orange/green. So I bought a battery. Does this sound like your issue?
