Question about Vizio VW42LF 42 in. LCD HDTV
After I have my Vizio 42" Class Full HD 1080P LCD HDTV on for less then 2 hours the sound cuts off and is replaced by this really loud high pitch buzz/noise. The only goes away once I totally turn off my TV for a minute or so. I have to wait for the Vizio name on the front of the TB to turn Orange before I'm able to turn it back on. This solves the problem for any given amount of time, but it comes back. My first guess it's a heating problem, but I have no way to check other then by feeling the back of the TV. This is getting worse by the day, I can't watch any TV without it screaming at me... HELP! i have the same problem....the sound shuts off ...when i go to a different station..then go back ..it works....so far this will be my ...4th...tv...i even had the vivio repaired ,,,which was all bords on it...ahhhhhhhh still not fixed....had direct tv from the head on the dish to the cable replaced.... WHAT IS NEXT... need help

SOURCE: are you able to use
Yes, all new TV's of 1080p specification will have a dedicated PC connection (and should have either a 3.5mm audio socket or 2 x RCA inputs for audio).
The most common way is to use a VGA lead (with 3.5mm audio lead) - VGA out of pc to VGA in of TV. 3.5mm audio output of pc (ie headphone socket) to 3.5mm audio input of TV.
You will just require the correct VGA lead long enough to connect to your pc.
The wireless keyboard and mouse will need to be connected to your pc, and must be within "line of sight" to the wireless receiver.
If you specifically want to use pc output to RGB input (and RCA audio in) of your TV, then you will need to obtain a long VGA to RGB conversion cable, plus 3.5mm audio lead. Have a look on Ebay for a coversion cable.
