Re: Dell Flat screen blackout?

Hi I have the same problem with 19 LCD monitors from Dell. This is how to check it. Power on both CPU and monitor. After the monitor goes blank, you check that you can see the image on the screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

Re: Dell Flat screen blackout?

Going from orange to green is what happens when the signal is getting to the monitor, (after you turn the computer on or wake it from sleep).
LOOK CLOSELY, at the screen, Can you see any image at all? even though it looks black?  Assuming you can, you probably have a BACKLIGHT problem as a number of us are having. This website:

has more info on this. They say it is usually the INVERTER board which is the problem which can be replaced. (more rarely the bulb(s) themselves).
BE CAUTIOUS if you should undertake a repair yourself, as there are places on the circuit board that say HIGH VOLTAGE, and reportedly will hold VOLTAGE even after the monitor is off. I believe there are ways of draining this held voltage, but you have to look into that. I took the back off mine and just avoided touching that part, but I haven't replace the board yet.
Reportedly, DELL will not sell any parts to consumers, like the inverter board. But check it out and let me know if I am wrong.
Please post any solutions you should find.

More likely to have problem in the inverter circuits, check for short between Emitter and Collector pin of the four transistors as shown in the pictures.

ViewSonic 19" flat screen monitor goes black - intermittently

There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed.
Let me know if I can assist you any further regarding this.
Best wishes,

My monitor screen goes black

The monitor is going bad. Either going to be a bad screen or a bad inverter. Also Since you tried it on another computer and its still giving you the same symptoms, you know the computers are fine. To be sure, try another monitor on your computer and if you get video on the new monitor then thats another way of verifying that the dell monitor is bad.

Monitor fades and turns blue

this sounds like a transistor issue concerning the ccfl lamps the power transistors are deteriorating and they will eventually go bad you can have them replaced and that should fix the issue. otherwise I would say have the capacitors that feed the ccfl's may be getting old and need replacement as well, its not something the average customer will want to do but if you have a service center that does electronic repair then that would be bst.
Hope this helps

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

Dell E151FPp 15 TFT LCD flat panel dim

Do you have the same issue when the cable is disconnected from the computer? If so, and the the brightness function doesn't change, then you have an IC Chip failure and the replacement boards are not available to you or me as Dell is Dell and everything from them is proprietary. If you are under warranty pursue that if not, time to replace. Consider this a time, unwanted time, but time to upgrade.

Oh, your right about the sacrificial diode on the power card... you wouldn't see anything.

Hope this fixed ya.
