Magnavox 26MD301B/F7 Volume/Buttons issue

[eagle00799]

Hello Everyone, Good to see this site up and running again. I have a Magnavox 26MD301B/F7 when I plug it in it comes on and the volume bar comes on the screen and turns itself down to zero. All buttons do not respond. The picture itself is fine but can't get volume to go up and stay up. Any ideas would be very helpful.
Posting rules say I am unable to post attachments, not sure why that is as I have posted them before but I will try to get something up here if possible.

They are push buttons, that is what it acts like but when I push the buttons they feel like they are free.

Disconnect the cable going to the buttons and see if that corrects the problem, if it does then change the button or better yet all of them.

Swap them out with some replaced buttons. I fix those on TVs all the time, it is a common failure.

Some buttons are 2 pin, 4 pin, or 5 pin (grounded) but they are mostly standard and can be salvaged from the buttons from other tv's including CRT.
