Question about Vizio VW42LF 42 in. LCD HDTV

1 Answer

Vizio VW42L HDTV

I was watching the tv last night, and it just clicked off. Nothing like bad weather or anything that would have caused a problem. It wouldn't turn back on - from the set, or the remote. I changed plugs ins; still wouldn't turn on. I checked the breakers, and that wasn't the problem. I tested the plug ins, and other things work in them. Any ideas? This tv was bought a couple of years ago, but really hasn't been used very much at all.

The minute it is plugged into the wall, the power supply (5vdc standby power supply) and the processor on the main board will be running 24/7 even when the TV is not turn on.

Does LCD screen backlight come on? If so proceed....
USE:CAUTION WHEN DOING THIS....
Try this if repairing yourself...find power supply, small board with no cover over it...check voltages on output pins/plug/connectors (white plugs) three in a row...
1 Plug has 24Volt supply..1 has 12Volt supply and 1 has 5Volt supply when read to ground (screw that holds board in) if you have these voltages it's a safe bet it's the main control board...I just replaced mine and it fixed a problem like yours.

It can be the unstable power supply due to bad DC filter caps, bad T-CON boards, main board.
I would inspect the power supply first for caps with domed tops.

My vizio VW42L has a picture, but the sound went out....how can we get the sound back


Use your remote and find RESET from the settings. I have a tendency to reset the sound on my TV's with all of my remotes, sometimes a different remote for a different TV or stereo will do something funky and turn off my sound the only way to get it back is to reset the settings and reprogram the channels.

If the backlights for the screen do come on and you also have 12v and 5v feed the main board then it does sound like the mainboard will need to be replaced.

Vizio GV42L 42inch LCD/HDTV


there are several possibilities. first if the unit comes on and the "VIZIO" light turns white, but no picture or sound, then the main control board is most likely the issue. could be the LCD control board(s) depending on model one or two. and ultimately could be the power supply on the upper side....if the "VIZIO" light does NOT turn white, the whole power supply unit is out. after that, would have to scope the circuits to find out. Seems that the control board is the most common and tends to happen on many different sizes. new board will be around $350.00. Might get lucky and find a used one, but it MUST be EXACT part or it wont work right. if you dont find one or want to sell yours for parts, id be interested in the screen. can reach me at kmarlin@grandvalleygolfclub.com. thanks, keith
