Sync buzz issue on a Zenith SE523223W
 

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

There was a factory mod for this problem. It was adding a resistor and capacitor. Is this set using a 9-181 board for signal? I sould have the OEM schematic on micro fiche.
