Today we just used our coupons (they expire Friday) at Circuit City and purchased two Zenith DTT901 boxes, both built in May 2008. The store did not have an DTT900 boxes on the shelf.
Once we brought them home, I installed the first one on the kitchen TV - a 14" Magnavox - using all of the composite A/V cables. It is a stereo TV. All the channels came in with a basic $10 RCA antenna, however, I still need to tune it to receive all the channels with clarity.
A little later I installed the other converter box on the TV (a 19" Curtis Mathes) in the upstairs bedroom - using only the video and left audio (yellow and white) composite A/V cables. The TV has mono sound. Everything works fine until I change the channel or turn off the box.
When I do so, the TV makes a quick "poping" sound. I have not tried the RF cable or connecting it to another TV but I imagine this is caused by the absence of the right audio cable. In the menu, the sound is set to mono. Does anyone have the same problem or is willing to explain what is going on?
I like the Zenith DTT901 boxes and jsut want to make sure that they are working as they should.
