Picture on Vizio HD 47" LCD TV freezes

I just bought a Vizio 47" model VO47LF. Randomly the picture freezes and sound goes off. There is no response to the remote or the switch panel. I have to unplug it and plug it back on and it comes back on with a very good picture. This has happened about three times but I am concerned since the set is not even a month old.

    This has happened to me also it's a 42" 120 hz brand new tv from Sams Club. I thought it was jumping the channel but it was frozen, I can't power off, change channels, or anything via remote or buttons on tv, the only thing that I can do is unplug it and then it's ok again, but it's happened to me 4 times within 3 weeks of buying it.

    Same thing with our Vizio VP 423. It is 2 months old and it has frozen twice today while watching NFL game. Unable to unfreeze until unplugging it and restarting.

    My Vizio HD 32" has the same problem with the same recovery procedure.
    LG has notified all their customers that a fix is available.

    I bought the 47" 120hz SV47OXVT from COSTCO a month ago and today the picture just froze, there was no sound and the remote or control panel wouldn't work either. After I unplugged it and plugged it back in it worked.

It sounds like a main board failure but it could be the power board as well, to find out your going to need to test the power supply voltages when it quits

SOURCE: vizio 47" lcd no picture no sound has power

this could be one of two problem. first, check if you have back light. If you do then the problem is with the M/B. Second, if you don't have back light then the inverter is bad and needs to be replace.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.

SOURCE: vizio 47" lcd, no picture,

Hi goldenstripm,
Power on the unit in the dark room then shine with the flashlight directly in the screen, you will barely see the images. This is because your backlight is not functioning. The following reason is the caused.
1. Power supply - missing B+(supply voltage) coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the B+ is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

If you feel comfortable opening the TV and know where not to touch, it seems reasonable to replace the board. On the other hand the new HDTVs are really coming down in price. Tough call. In my case my 32" WEGA failed (also a board) . I replaced it with a 32" LCD set.

SV470XVT Vizio picture freezes

Hello, This seems more like an interface problem then a board issue. Which interface are you using Component Video, HDMI or , RF(F Connector)? If you are using the RF (F Connector) there might be a problem in the tuner including the RF and IF sections on the circuit board. If you are using HDMI there might be a problem in the HDMI Integrated Circuit If you are using componente video the there might be a problem in the video circuits connected to the RCA jacks of the Component video input. If I were you I would have the take the TV back to the shop and have these items checked out, because board swapping is not the proper thing to do. I hope this helps, Thank you, Shuttle83

Vizio GV42L LCD TV screen black when turn TV on first time

If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in. 

I’m happy to help further over the phone at
