NO PICTURE BLACK IMAGEN,ONLY SOUND.MAXENT 50 PLASMA

I had the same problem with my 50 inch Maxent, found a solution on the internet that seemed too good to be true, but I replaced a part that cost me $1.38 at Radio Shack and my tv is as good as new. Go to this link for details and even includes pictures. All you need is a scredriver (to remove back cover) and a soldering iron - repair is actually very easy. Good Luck!

You should check the a/v cables, one of the yellow cables is probably broken if not you should get a new cable

There is an OFF/ON button near the inlet plug.. Turn that on...

Sounds like power supply switch needs to be changed to normal setting. If you are comfortable with electronics i will talk you through it if not you will need a tech or back to cosco it goes if you have a warranty.

Yes I had this problem. Unplug the power cord for 1 min then plug it back in. The tv will reset and the buttons then work again.

We seem to have had the same problem. Green light keeps blinking but will not turn set on or off. I unplugged the set for a few minutes, plugged back in and works fine but will happen from time to time for no reason.
