I've fixed several of these, easy fix, you will need to replace both 470uf 35 volt capacitors on the master and slave inverter boards. So you will have to replace a total of 4 capacitors. The capacitors themselves are about 50 cents a piece. The inverter boards are on the far left and far right of the set. You will have to remove the back cover to see them. If you don't have the ability to replace the capacitors, you can just order new inverter boards for $40-$60.

SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

It's likely not a backlight, but a mainboard. If you are feeling frisky, take the back off and get the model number off the mainboard and check eBay.

Vizio damaged screen


From what I have heard the screen is likely to be ruined and need replacing.
Replacement screens are available but throwing the tv away and buying new seems to be the popular option.

It is probably time to contact your household insurer...

How do I change the screen resolution on the TV from "standard 420" to HD?


The screen resolution will automatically change based upon the resolution of the input signal.
Are you using an RCA connector? Perhaps an S-Video connector? NEITHER OF THESE ARE CAPABLE OF PRODUCING HD VIDEO!!!
In order to view HD video, you must use one of the following:
  1. HDMI connector (optimal)
  2. DVI connector (almost as good but requires a separate audio connection)
  3. RGB video connector (also requires a separate audio connection)
If you are using one of the three connection types above, contact your DirecTV representative to find out how to switch your cable box output from SD to HD.

Why is My vizio tv blinking


May I ask the model # ? If it is a VW42LHDTV10A, the problems is caused by faulty capacitors on both inverter boards.

Strobe


Check the capacitors on the master/slave inverter boards. I just repaired a Vizio VW42LHDTV10A with the same problem. Cost to repair $2. The master and slave inverter boards should be on the far left and far right sides of the TV set. They both have metal covers installed over them so you will have to remove the covers to access them. I'm willing to bet the tops of your capacitors are bulged.

First, try setting all display settings to default or 'normal' or 'standard' and disable any picture processing functions. If your TV is LED backlit then the LED dimming function may not be working correctly (dimming is done by rapidly switching the LEDs on & off).
