Sony Proj Tv model #kp-53v80 : sound fading in and out

I have a Sony Color Rear Projection Tv model KP-53V80. Recently the sound has started fading in and out. There is no consistency to the lass of sound. Sometimes it's just a few seconds and sometimes several minutes. Any suggestions?

    I have the same problem, and my surround is turned off. I don't seem to have an option for expanded.

    I have the same problem and it's drive me nuts. NO rhyme or reason as to why it does it. Sometimes it's hours before it starts and then other times it starts doing it right away.

    Make sure the "expanded audio" or "surround" feature is off. See if it still does it.

My 12 year old Sony KP-53V80 TV suddenly turned off and will not show a picture just a small rainbow at the top of the screen, then a whistling sound, crack and turns back off. can you help?


sounds like the inverter went bad...There's a high voltage device in there that runs the whole "picture" thing. There are capacitors involved with it that have probably failed leading to this mess.. That would be what that "crack" is...If you try to turn it back on does it just "click " and then stay off?

KP 53v80 is way too old to be fixing---recycle it as most landfills will not take that as it has toxic Glycol inside of it.

Sounds like one of the tubes is shorting out causing the set to go into a shutdown status so it won't cause any major damage to the set or house.

It's not a digital hi-def tv, so you either need a cable/sat box..or a converter once hi-def goes in and analog stops.
