Zenith dvd/vcr mod #6711R1N211C. Need to prog the volume button.
In my manual, to control a sony TV.. the code is number 8 or number 9.
You will hold down TV POWER, hit 8 then release TV POWER.
If that doesn't work, try number 9. Once the batteries are removed, it resets the code, so write it down. It will also over ride your old codes once you input the new one.
Note: Depending on your TV, some or all buttons may not function on the TV, even after entering the correct manufacturer code.
I looked for the section on Stereo, but all I found was the above.
Hope this helps.
