Quoting from link:

"You will need to have have the original remote for the TV for this to work. On your TV remote control press and hold down the MENU button and the VOLUME DOWN button on the TV itself at the same time for at least 5 seconds. If that doesn't work try holding down the '0' button on the remote and the VOLUME DOWN button on the TV itself at the same time for at least 5 seconds."

The solution for the problem is to replace the control PCB. The PCB is the printed circuit board that controls the volume, channel and menu buttons.

These parts can be found and bought from Sears parts direct.

A break down of the cabinet parts can be found here.

You will need to replace the Sub PCB. Its about a $50 fix if you do it yourself.

You can find the part here.

Its part 510.

This circuit board controls the volume, channel, menu buttons, ect.

My TV was doing the same thing. Someone told me to disconnect the front menu buttons and this worked for me. The board goes haywire. You have to take off the front black panel on the bottom first then the grey front panel where the controls are. Once you do this you will see where there is a plug from tv to the panel where the control buttons are. Just disconnect. You will only be able to use your remote for TV. Its a cheap and easy fix. Just lots of screws to get the panels off and on. Good luck!

Order a color card for like 10 to 40 dollars put it in and it should make ir as good as new. you can get them from a tv part site. and 1600 dollars isnt possible they are 899 new at brandsmart.
