Question
have a 42 inch Vizio, model # E421VO, searl # LAUKIFEN 1201428.

The proplem I am having, the cable company hooked up a hdmi cable to my tv. Sometimes when I switch to a HD channel I get no sound. The Tv freezes up with a black screen. I have to unplug the tv and plug it back in to get the tv to work. Could you tell me what could be wrong?

Answer
this is a known issue. it is the box not working with the tv. you need to go into the cable box setup menu and change the audio output setting to stereo or PCM. this will fix your issue. if you cannot find this setting call your cable company.

In order to properly assist you, it is very important that you provide the Model number of the television and the year it was manufactured. You can find this information on the back of the TV. Please also let me know if you are trying to fix the unit or just need to know the cost for repair. If you have a digital camera, and know how to solder and use a meter, I can help you fix your unit in most cases.
