This may work for you. My Vizio went black except for the blue channel rectangle in upper right corner; I couldn't change the channels or power off. I called Vizio, was told I needed a hard reset, and this fixed my problem: I unplugged the TV; held down the on button for one minute, then plugged it back in. It works fine now.

You need to replace the power supply part # 0500-0507-0250
about a hundred bucks with shipping.

Not to be a smart alek but buy a new tv

Did you hear any pops before the screen went black?
You've tried completely discharging it? Disconnect everything off the TV, all cables and power.
Press and hold the power button on the TV for at least 20 seconds.
Let it sit, and in about an hour, plug just the power in (directly to the wall) and see if it comes on. There should be an indicator light, is it white or orange now? Was it a different color before?
Odds are it's a board, be it the main or a video, don't know for sure. If you can take the back of the TV off and see if there are any evident signs of damage, blown or swollen capacitors, burnt traces or resistors/diodes, etc.

There is a processing fault that is starting to occure. What you are seeing is a type of aliasing. This can be in the main signal processing or in one of the control areas.

The set will require service. The service rep will test the set by using board substitution. There are typicaly a number of areas in the TV set that can cause this type of fault. Once the defective board is located the fault will be easy to service with a simple board swap and some adjustments.

If the set is out of warranty, it may be expensive to service. With many of the no-name brands, spare parts can be difficult or impossible to have.

Your DirecTV signal is probably too low. That would produce the small black rectangles (pixilation). Also, try replacing the cable you are using to get the signal from the DirecTV receiver.
