Chances are the backlight for the screen has failed. With the set on, take a flashlight and shine it at an angle onto the screen. If, when looking closely at it, you can see a faint picture, then the backlight circuit has failed. This can be either die to the inverter or the lamp it self. Depending on the age of the set, repair can be more costly than replacement.
There can be many things that can cause a jumping or unstable picture. The power supply is the starting point. You would have to be able to monitor the voltage outputs to determine if there is instability.
Then there is the testing of the circuit boards by monitoring the proper waveforms, as per indicated in the service manual. You will require the proper test instruments for this. Once the defective board is found it will have to be replaced.
If the set is out of warranty, it may be more worth while to replace it. Servicing out of warranty can be too expensive to be cost effective.
This message is generated when the backlighting tubes have aged so much they no longer are capable of operating normally - it's not a defect, your monitor has just worked too much.
You could replace the tubes, but new ones will cost you more than a new monitor. So either get them from a defective monitor sold for parts or just get a brand new monitor.
I'm assuming that on normal tv/cable stuff it does this as well.
This could be a backlight problem or a mainboard problem. When the tv blacks out you need to look at it (maybe use a flashlight) very close and at a slight angle at the side. If you see an image that looks normal but very faint then the backlight or its power supply is the problem. You may see the menus when you look this close but when you back up to a normal viewing distance everything fades out.
The backlights are not an expensive fix usually about $100 if this tv has a sub board. If the inverter circuit is part of the main board then you may see the cost rise to over $400
Check out the screen and then contact Dell and any local tv shops. Get estimatesfor the repair cost. And keep an eye out for what a replacement tv is worth. Backlights go out on any lcd device such as tvs or laptops. The repair cost for those using sub-board is now reasonable, unfortunetly those models with evreything on one big board are not cheap.
The mainboard is damaged, Not really sure about the cost but Samsung parts are not really expensive, I believe it should be between $50 - $100 just the board, and you will need to pay for someone to install it.
The complete failure of the LCD display panel is quite rare; far more likely the backlight or the power supply for the backlight has failed and neither of these will cost as much as the entire panel which may not even be bad.
If you take it to an independent repair shop, insist on getting any replaced parts returned to you.
I have just did this here is the solution for you:
Philips screw driver
Small Flat screwdriver
Make sure your desk is clean and you also need a piece of soft clothes because you need
to place your LCD Monitor face down.
How to open the back cover:
First, remove all screws on the back cover, then, use a small flat head screw driver to
the plastic Clip inside the LCD Monitor star at the bottom of monitor. Then you can easily
separate the front bezel and back cover like the photos shown below.
