Have had good picture in the past, but now the quality is poor. Did not coincide with any new hook ups, and the TV downstairs on the same comcast service has a better picture than this one!! This TV is only 4 years old. Tried a new DVI cable from cable box to HDMI slot on TV, still no improvement. Is it possible that the TV is degrading this soon? We don't watch a lot of TV, so I doubt it has many hours on it. Any ideas? Thanks

Re: Poor Picture Quality
Try another cable box on the TV. I have seen these fail and cause problems. If the TV is okay with a DVD player, and not good on the cable service, most likely the fault is with the cable box, or the HDMI input circuit in the TV.
With the process if elimination it is possible to functionally work out where the defect is.
It is possible to have any TV fail. Both new and old sets can fail. Naturally, the older the set the greater the chance of failure, and reliability decreases with age and or use.

Check that you are receiving a signal of any sort by way of satellite receiver,cable box,dvd player any good digital source, check cables between the source and tv to make sure they are good swap them around if needed, we are trying to isolate the problem to the source or the tv?Polaroid panel tv's are very poor quality and are not rated for very many hours of operation, you may have a dead panel and that means throw the tv away and buy a new one.(of better quality this time)
First of all do you have a HD signal?
these sets are made for HD and most look good when you set the HD box to 1080i , the cheaper sets do not look good with a non HD signal.
check all inputs, dvd, HD air, and component and post which are bad to get more help
If the input to a HD tv is not in HD format the tv won't display an image very well. Be sure your input to the tv is compatible with the tv's technology for optimum performance quality Also re-check the input source (such as converter box, dvd player, etc..) and be sure you have the correct input/output ports connected properly. Try to reset all yout tv settings back to manufacturers defult specs. When an input signal is sent to the tv most modern tv's have software built in to select the proper format to display the input image. There may have been a mismatch communication error when your tv software tried to "handshake" with your converter box input signals from its firmware. So try a reset solution and re-connect the tv without the converter and see if that helps. If not e-mail me and I'll determine if the tv needs technical servicing.
