Re: Audio problem

Signs of a defective Filter Capacitor. I suggest you replace all capacitors in the Power supply and try.

Getting a loud hum only from video function.

Check your connections. Chances are you may have crossed the RED video cable and the RED audio cable.

The system shuts off after a few minutes

It could be overheating, have you checked how warm it is? Is it in the open. Zenith systems seem to have a lot of problems associated with them

Loud hum when DVD selected. No hum when radio or audio selected.

If it is only affecting the DVD, are you coming in with analog or digital audio from the DVD?

If analog, disconnect the cables at the HTS and see if that solves the problem. If it does we look out toward the DVD, possible cable picking up hum. from proximity to a TV or power cord, bad shield, etc.

If not, yeah, something internal and needing a pro to peek at it.

321System No sound just humming with TV connected to Video1 or 2

Get new audio cables . It seems there's a broken Ground (shield ) wire somewhere in the cable. NO ground means HUM usually

No audio for tv?

Since not all devices have the same in/outputs available, if you are trying to interconnect them, it helps to know the make and model of both, not just one.

There are several possibilities to connect external devices to your 'home theatre' system.
The one we have delivers the best when S-video is used but that requires a separate path for sound.
The standard colors for audio in and outputs are red(=right) and white(= left) and often cables are supplied with the same color coding.

The usual connections will be named 'Line in' and 'Line out.' The outputs deliver specified voltage into a specified load (or termination) and the inputs expect that condition.
This ensures that volume controls act in a sensible manner.

Whining noise

The problem i had was when i would play my tv. I had it hooked from my dish to the sony then the tv. When i played a dvd,cd or the tuner it didn't make that noise. It seems my video/audio 2 channel was going bad. I disconnected my rca jacks and used the optical audio connection. The noise stopped and i got a better quality sound.

hope this helps

Ringing noise

try changing the cable going out of tv to the system for audio, make sure the cable from tv/sat receiver is in audio out and in dvd player in the Audio In under the Video 1 bracket, then when you turn on the system click function button on the front panel it will show Video 1 on the LCD and that should work.
