my tv sound sometimes goes off for no reason or if i change

Resolved Question:

my tv sound sometimes goes off for no reason or if i change from an hd channel to a non-hd channel. it doesn't happen every time and hasn't for months and just did it again. if i turn the tv off and on again the sound comes right back.
i have cable tv and i was wondering if it was a cable connection issue or a sound set-up on the cable box..

Sorry to hear about your problem, I will be happy to help. I hope you find the time and information I provide to be valuable and will honor the good faith system of this site. Please be aware the answer to your question may not be good news and the procedures that are required to solve your problem may be complex and could involve replacing parts that can be expensive.

Solving your problem depends a lot on your ability to follow directions very carefully, be patient, and continue the communication process with detailed responses. The more information you provide the better chance of solving your problem.

There is probably nothing that is failing on your setup it's just the nature of digital connections to once in a while get errors. Every time the Tv has to change resolutions it has to go through the digital "handshake" process and once in a while an error will occur causing strange things to happen (like loss of audio). Some major manufacturers have software updates that can remedy this, but Polaroid is not one of them.


Your best bet is to set the cable box to always output the same HD resolution. This can be different for every cable service and box. For comcast- leave the Tv on and only power off the cable box, now press MENU on the comcast remote, in a few seconds a hidden menu should appear. If there is a setting for 4x3 override that is set to 480 something, then change that to stretch or something that will not make it switch to 480. To exit just press MENU again, then press power to turn the box back on, try some SD/HD channels to test your work.

i can do that however i have the same tv in aother room and i'm not experiencing any problem with that one.

that one has an older cable box different brand box and remote and i have to use both the tv remote and the cable remote--the tv remote to turn on the tv and change the sound and one for the box to change the channels.

i guess i should call time warner and have them come out and change the box. using two remotes is ok and it works.

i was hoping there was something simpler because sometimes it takes them weeks until they can schedule you.
