Get my mute button to work - DISH Network Televison & Video

You must take apart the two halves of the remote .
Remove the rubber buttons bad (It usually is one piece)

Get a bottle of 99% iso alcohol at any pharmacy and let the whole rubber pad soak for 2 mins.

While it is soaking, take the end of a rubber pencil, and use it to clean the pc board by rubbing in circles on the printed resistor ink pads individually.

Remove the rubber button pad from the alcohol and dry well.

Take the pencil eraser and rub each individual black resistor ink with it.
Then dip a Q tip in the alcohol and do ALL of the resistor ink on both the pc board and the rubber pad.

Re assemble and there you have it!

Usually when you open the remote and pull the rubber all in one button key pad out, it will be sticky, so clean the button holes on the top piece of the remote (The Insides Individually) or the problem will continue.
The rubber keys will eventually return to rubber and the small black resistor ink on the opposite side will also wear in time.

I have seen this in the shop now for almost 30 years, and it is 95% the same every time!

I hope this will help!
