Sync buzz issue on a Zenith SE523223W

[mpatoray]

Hi all,

I know this is not an antique, it was made November 1988. It was a curbside rescue and all it needed was to have the channels reprogrammed so that it could get 3 for a VCR and 25 for my dish receiver.

It has a great picture the only problem is that the sound has a constant buzz in it, like sync buzz that gets even worse wen text comes on the screen. Is there anything that can be done about this.

Also doe anyone have a sams for this set?

Thanks,

Matt
