Buttons on television won't work Screen continually displays demonstrations of sleep mode, closed captioning etc I can receive channels but these demos will not go away they are full screen It is hooked through DISH but worked previously

Your TV appears to be in what is known as DEMO MODE, which is used when the TV is set up in the store on display.

In order to disable that mode and return it to normal operation, try the following procedure:

Turn on your TV.
Hold down the VOLUME UP and the VOLUME DOWN buttons at the same time for 10 seconds.
Be sure to use the buttons on the front of the TV and not the ones on the remote control.

Some models may turn off at this point while others may not. Either way, the set should now be ready for use in NORMAL MODE.

If that does not cure the problem, then check in your OWNER'S MNAUAL for the exact procedure on how to disable the demo mode feature.

I hope that was helpful to you, good luck and take care.

Joe.

Could you please provide the model number of your TV?
It appears that the TV demo was activated by accident.
