Hello. After much careful research and comparison testing, I finally settled on a Philips-Magnavox TS3259C 32" television -- $429 demo unit on clearance from Sears (who often have great deals by the way).After bringing the TV home and connecting it to my Toshiba SD-1200 DVD player, my wife and I immediately noticed alternating vertical bars of lighter and darker black when the TV was switched to AV1 and AV2 channels. These bars were still slightly noticeable during DVD playback in letterbox mode. However, they are not visible when viewing cable broadcasts.
My question is, what is causing this distortion? My theories include electrical interference from power cords, signal from nearby devices (receiver, VCR, DVD, CD player), or the TV itself in which case it's going back! The S-video cable is a quality Monster Cable I picked up for a direct DVD-to-TV connection. I am using an F-connector from my VCR for the cable channels. (A second question: would using a cable with RCA connectors from VCR to TV improve the picture?)
BTW, I moved my speakers 20' away from the TV and this did not help. Any advice would be much appreciated!
"signal from nearby devices (receiver, VCR, DVD, CD player),"It sounds like you've found the problem from your response to Victor, but you might try turning everything else off. My Theta Jade transport puts out an enormous amount of RF (?). I use rabbit ears for the TV and when the Jade is fired up it completely wipes out one channel and puts distortion in the others. It only affects broadcasts tho, not tapes.
***My question is, what is causing this distortion?Most often the regular vertical bars are caused by reflections in the cables. But it is more common in the RF cable system. I personally have not seen it with the S-video channels. As far as what is defective - that is hard to answer. Could be the driver in the DVD, theconnectors, or the TV receiver. Often a poor connection will cause it.

There are some possibilities there too. I would try disconnecting all cables from the TV except te S from the DVD. If this is clean, start connecting the other ones one at a time.

Generally speaking using the video cables in place of the RF should improve it.
I have now learned that this model suffers from poor shielding of its power source -- something that I was not able to uncover despite extensive research. (Actually, another model of the same brand was well-known for exhibiting the problem but it was not attributed to the model I purchased. I just hope the retailer takes it back!
