Question about Vizio GV42L 42 in. LCD Television

1 Answer

Digital channels freeze

After a viewing period, HD stations received over cable (Comcast, no box) will freeze. Sometimes, you can power cycle the TV and they come back. Sometimes, it takes longer. I have another Vizio 32 inch and it still has the stations at that time so I know it is not Comcast. The first unit was replaced and the new one has the same problem. Any suggestions?

    Hi i Have the same problem,when called Vizio they told it could because of interference between my wireless router.

    I believe the tv sucks that's all.

    freezes on the digital fox channel, but if i manually punch in the
    channel it doesn't do it. WTF.

    Same problem. Channel 5-1 in particular causes a freeze. Once frozen the digital tuner no longer works until I power cycle the tv. Called Vizio and got a new main board, but the problem popped up again after a few months. Any ideas?

    I have the same problem with a 52", supposedly the top of the line Vizio LCD.

    Thanks. Late last year (maybe December), the problem seemed to go away also for us. Vizio had originally claimed that it was a signal problem with the provider (Comcast). I had never checked this out with them. In our case it was more than one channel that could cause the problem. I suspect Comcast made some changes that inadvertently corrected the problem.

    I think I have a related problem now with TWO 32-in Vizio LCDs. The TV will unexpectedly switch to channel 5-1. It's not like a nother remote is triggering this. If I push the "Last" button on the remote it doesn't go to the previous channel as it does if I enter 5-1 from the remote. They had sent out the repairman who changed three boards, but the TV then didn't hold onto all the programmed channels when the TV was shut off. I took it back and got a brand spaking new one and soon discovered that it also would unexpectedly switch to channel 5-1.

    My Vizio VO22L freezes up on digital channels up to 3-4 times a day. I receive the signal from Comcast (figures...) from a coax cable with no cable box. the only way to clear the fault is to unplug the set and plug it back in again. I've called both Vizio and Costco support and both are stumped. I've heard it may be a problem with the signal from the cable provider.

I also had this channel 5-1 freezing problem and spoke with Vizio support a few times. They thought the problem was the SSID code from the local CBS station and said they would try talking with them. I am not certain if they did this or not, but, as of mid December, my Vizio no longer has this problem.

Just bought a Sony XBR9 and Comcast gave me a Motorola DCT6200 box which has a DVI output to a HDMI input into the TV. When switching from a HD channel to an analog or digital channel, the picture is...

I am having the exact same issue. It started happening within the first few hours of turning on the XBR9 for the first time. I also have a Motorola box from Comcast. This did not happen with the HD TV that was hooked up previously. Did you return the TV?

I also have a Brand new Sony Bravia 52" LCD with Comcast Cable (motorola box).When switching between HD Channels sometimes the left side of the screen shows a smushed version of the new channel, and the right side is a frozen picture of the previous channel. I correct this by switching to a non HD channel and back. Cable or TV problem I wonder?

Am i getting hdtv with just cable feed?

Depending on your cable provider, some of the HD channels may be present. If so, these are ususally located in the upper channel numbers. It sounds like you are receiving some of the HD lineup. A cable box will probably allow you to view more HD channels including the premium HD channels if you subscribe to them. You should not be noticing a delay with the HD channels only. If this is what you are experiencing without a cable box, then it would be an issue with the HD tuner built into your TV set. LG customer service can let you know if there are any software updates available for yourmodel that can resolve this. Additionally, if you are getting your sound from an Home Theater system then you will notice an echo if using the TV's built in speakers at the same time. This is sometimes mistaken as an audio delay. If you are using a home theater system, be sure to disable the speakers that are built into your system.

TV freezes when switching to a digital channel

The problem your describing can be contributed to your cable box. Depending on your cable company there are times when the box has trouble translating the signal to the tv. You tv is operating normally. Suggest to the cable company to switch your box.

Sound cuts out- cable tv

I had the same problem when I installed the new HD Comcast cable box (DCH3200), initially with my CRT through RF, then with my HDTV through HDMI. Problem solved when I replaced the box with the Comcast RNG110 I got from my local Comcast. It is a neat miniaturized box and it works extremely well on HD. There is no power switch on the box so before activation do not forget to put it on with the remote (cable, power, the green light will come on).

No Non-Hd sound

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

I purchased a SANYO-DP46848 42"HDTV. I have a Cable box and my cable provider (Time Warner Cable) provides free HD Channels. However.... I CANNOT PICKUP ANY HD CHANNELS ON THE NEW TV. WHY???...

I just got the same exact one, when it searches automatically the first time it doesn't look for digital channels. go to Menu>manual channel search>cable. it will look for all possible signals and will take forever probably. the free digital channels will take several seconds to switch channel to channel, but they're there! They will show up on your screen as "DC 91-2" or similar. you can switch back to regular cable channels with the input button, you just cycle through all the inputs. hope that helps.
