Question about Televison & Video

Open Question

Good Morning, I sure hope you can help us. My husband was up this morning watching our Vizio TV model #SV420XVT1A when all of a sudden the screen went white and there was this loud noise. My husband tried to turn the TV and the cable off via the remotes but they would not work so he flipped the power button on the surge protector to shut everything down. He waited a minute and turned everything back on but only the cable box would power back up, not the t.v. Please advise...

SOURCE: thinking about buying a used Vizio 42"

Don't buy it. VIZIO is not standing by their products.

My GV42L had issues from the ssart and now it shows No Signal and shuts of in 2-3 seconds. I read many similar issues on this site with VIZIO.

SOURCE: VIZIO TV Black screen. Cannot turn off TV without unplugging.

I had a similar problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. I didnt hear an arcing sound though. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound. I would check the ceramic fuse first on the board that gets power from the plug.

HOW I FIXED MINE: I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine.I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

The main digital board to your TV should be troubleshooted. If it found faulty, there is no other way than replace it as card basis. There is no repair to these boards. Very like computer motherboards.

I hope you get a response. I am having the same issue. It turned off on my this morning @ 0600 and then after getting home from work I was cooking dinner and was wondering who turned the TV off. It did it again.
Then it happened about three hours after that. I wish I knew what the problem was!

I have an opportunity to buy a Vizio Model SV420XVT1A television that has cracked screen for $100.00. How do I repair something like this or is it even worth the effort?


My suggestion would be not to buy it since the screen is the most expensive part of the TV and is not repairable unless is replaced. The price for a new screen it might exceed the price of a new TV.

I have power but no picture.


Hello tbdbitl, First I want you to check all of your inputs, to make sure you have proper connectivity. If your connections are good, then you may have one of two problems which are: 1) defective backlight 2) defective power supply inverter In both of these cases you will need to perform one test. With the TV in a dark room, turn it on and using a flashlight look at the screen and see if you can see an image, if you can see an image then the problem is either in the inverter or the backlight. In either case you need to have this looked at by a qualified TV technician, because these parts are not user servicable. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com
