Picture but buzz instead of sound on Zenith 17T20 TV
11/19/2004 3:10:09 PMDave Froehlich
Hello All,
I solved the picture problem but I cannot seem to solve the sound problem. All I hear is the buzz of the scanning section but no audio sound. What mistakes might I have made? I have tried adjusting coils but it has no effect. The buzz control does absolutely nothing notcable. It could be working but with the frequency off I can't tell if it is.

Please help.

Thanks,

Dave...

Hello again,
I found that R57 was open and was hearing sound for a good long time. Then when I had the sound perfect, the fuse blew and I am back to square 1. I only have a few fuses left. This is getting very expensive at $1.50 a fuse. I don't like to burn money this way.
I am going to try the 100 ohm resistor trick that Norm mentioned.

Thanks,

Dave...
