Zenith inteq iqb50m90w has no sound, hooked up cable box with component cables

I got this tv from my father in law who had it set up with a Bose sound system. Speakers have not been used much on the tv. I tried switching the audio output switch to no avail. I have tried every wiring combo possible. Any help would be greatly appreciated.

To be honest I do not really understand clearly your issue so I will pose a few questions that might clear things for me up:

1. No sound from internal speakers.

2. Speakers have be checked and are not open, disconnected or switched to external or variable audio out only.

3 A DVD or similar connected to a rear video and audio input has no sound.

4. The set had sound when hooked to the bose system.

Do I understand correctly or did I miss something?


If all the above is correct the set has a audio output problem (old trick is put ear directly to a speaker and see if anything, a buzz, faint sound or nothing at all.)

Snow no connection to cable box


the fact that you are seeing snow tells me that your tv in in the tuner mode .. your cable box is more likely hooked up to the AV input (composit video + 2 sound channels ..3 wires total) .. or it could be hooked up to component inputs (5 wires total) ... you will have to go to the menu of the TV and choose the proper input ... if your cable box is actually connected thru the tuner (coax cable to RF input .. one cable) then you have to select the same channel on the tv as what the cable box is set to .. that is usually chan 2 or 3 ... there is also an svideo input on your tv .. that can take the place of the composit input ..
here is a diagram of the back of your set so you can determine how its hooked up ..

Bose lifestyle v20 sound but no video


The problem turned out to be the TV itself. Somehow all the a/v and component cable inputs on the back of the TV got disabled. After finding then consulting the TV manual online (the TV is about 8 years old), we found there was a way to reset the TV to its original factory settings. Voila, the a/v and component cable inputs were enabled again, and everything worked correctly afterwards.

Connecting bose 321 system to lg hd flat screen,bose receiver plays fm am ok threw speakers.tv will not play threw bose speakers.bose dvd plays sound ,but no picture


You will need a Component Video Cable
Connect the Red Green and Blue Connections from the TV to the Bose.

if your audio is coming from the TV, also connect stereo audio from the TV's audio out to the "TV" input on the bose.

if you want to hook up other devices (VCR, BluRay, etc) the video will go directly to the TV and audio will go directly to the Bose

"No Signal" when DVD player is hooked up via component video


If you are using the same cables,same input and the cable box works ok. I would look into the settings of the DVD player. Such as is it a progressive playback and is progressive turned on. It is not turned on by default because not all TV's could handle progressive in.
