Can you pelase help me? I don't know what happened. I waswacthing TV on my 37 inch LCD Polariod TV and then my dog hit a button on the remote and then no sound? I tried to hit all kinds of buttons to get it back on (including Mute obviously), but nothing. Can you please help me?
Make sure the speakers aren't turned off. It will be in the menu section under audio or sound. If you can find no other reason and you take the back off the set, look at the top of the bottom board. With a ohm Meter look for a Suface Mounted Resistor at the top of the board marked 100. Check the resistor on ohm . If it's over 100 ohms replace it. I don't think your dogs to blame.

It sounds like you are saying the "video looks scrambled but the audio keeps playing OK"
Normally this is a Video Processor Problem that requires a Board to be replaced.
When the problem happens, can you see the TV menu or the TV's On Screen Display clearly.
I suggest checking to see if the problem happens with the video inputs like, Composite(yellow/red/black), component(RGB/yellow and black), HDMI and S-video. If it happens to all inputs then you need to replace a board.
My 37 inch vizio did the same thing. go to your menu screen on the tv and go sound. My tv has an option to turn speakers on/off. Once I turned my speakers off and the back on again everything worked great. hope I helped! if I did please let me know! youtube.com/xniax1
