    For no apparent reason the screen goes blank - occasionally the image returns, but generally I have to reboot.

    same prob: the power light keeps blinking but the monitor won't turn on when I hit the power button. ???

    My Dell flatscreen monitor just went out on me. The green light is slowly flashing. I tried to unplug the power and it still didn't help. When I turn the monitor back on the screen flashes quickly and then returns to black. I hooked up a different monitor and it is fine so I know it's not the computer but a monitor problem. Any suggestions????

    My monitor went black and the power light blinks green. None of the buttons work. The only way to turn it off is to unplug it.

    Having the totally same problem with my dell monitor. Hmm. Seems to be a trend!

    The screen is completely black, but the light indicating that it is on is green when the computer is on, and orange when the computer is off. I connected another monitor, which works fine, so the computer is OK.

    Monitor goes to black (often after a full screen graphic display) and power light flashes yellow & green. Sometimes lasts for a minute or so and then desk top reappears.

    Power on/off button does not function during this process.

I get this problem too, usually I just punch the moniter(not on the screen part) until the screen comes back. its pretty effective but annoying to do every few hours.

SOURCE: Power Light Blinking & Black Screen

A blinking blue light indiactes that your power-inverter board is not putting out what it should. It needs an overhaul which may be a simple as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

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

SOURCE: Dell Blinking Power Light

There are 4 transistors that go bad due to various issues (one being a cold solder issue with the power inverters for the transistors. I had this fixed and replaced the transistors. They lasted about 10 months). The 4 No. 2SC5707 transistors must be desoldered and removed, new ones put in their place and resoldered. I took the parts (transistors) and the removed power/circuit board from the LCD to a tv repairman and he did the repairs (de and resoldering) for about $60.

Blue light on with blank screen dell SE198WFP monitor

It depends on what type of connection you are using. If you are using a VGA (analog) cable then you need to select that mode on your monitor menu. If you are using a DVI (digital) cable then you need to choose that mode on you monitor menu.

I have a Dell Dimension E521. When I cut the power on everything comes on including the monitor, but the monitor will stay black. It does say something about power save hit any button but the screen

A solid green light means the computer is operating normally.

A solid yellow light indicates the power supply is operating normally but the computer is not processing data.

This could mean there is a problem with the CPu or another component on the motherboard.

((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))

A blinking green light means the computer is in standby mode.

You should consider visiting Dell Support and downloading the manual for your

your Dell computer. So use the LED power light codes if your Dell computer has them.

hope this helps

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

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: 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.

Dell - 17" flat screen

This sounds like the back light is gone on the monitir... to check this look very close at the monitor whet the PC has booted, if you see a VERY dim image on screen then it suggests that the back light is gone.

Many monitors hace a 3 year warranty so I would try a warranty claim before throwing it away
