Question about Dell E151FP 15" Flat Panel LCD Monitor

1 Answer

Computer monitor display blank, LED flashes green

I have a Dell flat panel display E151FPb. The green LED light next to the power button is constantly blinking, but the display is blank. What might the problem be? Everything is plugged in properly, the display was working a few hours earlier. I went in to use the computer and the green light next to the power button is flashing and the screen was blank.

There are numbers of causes for the monitor black out. The most likely case with yours is with the over heating problem. What i mean is not the monitor, but the cpu components like processor, ram, hardisk, or whatever it may be. So you need to check them once again. As the first step, please disassemble and clean all the parts inside. If you have coolant paste, apply little paste on the heatsink. Blow away all the dusts, and again after you've finished cleaning, assemble the machine, reconnect everything and reboot the system. Sometimes the display refresh rate can cause the problem, but i don't think, that's related to your problem. If there's no internal defect, we can troubleshoot and fix it somehow. There are number of measures. If the above given tricks can't fix it, let's try another. Do let me know. Good luck.

    Unfortunately, that did not work. I cannot tell if the monitor is off or on. If it is plugged in the power light constantly flashes green, regardless of whether the computer is on or not. I cannot make the light stop flashing unless I unplug the monitor.

    Can you please try it on another Pc? If it works on another system then we'll only need to deal with your cpu not the monitor, but if isn't then, there's problem with the monitor which needs to be serviced. Please let me know, awaiting your response.

Next thing I would check is the VGA cable between PC and monitor.

Make sure is in at both ends and if possible try another one.

Do the Dell Menus come up with no VGA cable plugged in? Is the light amber? Flashing or static?

Please disconnect the Monitor Data cable from Computer.
If you see Dell Colored bars, it means, monitor is working fine,
If still black, please ask for replacement, since Monitors have 3 years of warranty if not purchased with the computer.

Now connect the cable back to computer and turn the computer off by holding the power button on computer and turn it back on...

Blinking Green shows that computer is in sleep mode......

Hope this should resolve the issue.
