VIZIO VS42LFHDTV10A Freeze Up

My 13 month old VS42L would ''freeze up'' randomly - picture gone or frozen, no sound. Backlight stayed on! No remote control or side buttons had any effect. Only way to regain control is to cycle power. Warrantied under Costco extended program. Unit repaired by contract repair company by swaping out video board, power supply and a cable. Same problem next day. Costco Concierge set up replacement unit from VIZIO.

Company certified replacement received yesterday (6/18/09). Replacement has same freeze up issue with seemingly increased frequency of occurence.

Only connection is RF cable to Comcast. No switches or tuner boxes. Unit sits in a large recessed area, but measured temp at highest point seems to be withing operating temp spec.

Any ideas?

Just unplug the comcast and see how the tv works, if the TV works fine, then you will now the trouble is not your TV.

It is not likely to have the same issue in the new TV, just unplug everything and use a dvd to see how it handle it.

My 6-month old tv is making intermittent 'buzzing" sounds. It was a Christmas gift and I don't have any paperwork on it but it did come from Costco. What should I do? Thanks so much.


Humming usually begins when the backlight setting is low. For some sets setting the backlight anywhere from 95 to 100 works. Most wok at 100. So turning it up should get rid of the problem. You can follow the 5 steps below to change the backlight setting.

1. Turn the TV on.
2. Press the Menu button on the remote, located right below the channel changing button.
3. Press the down direction button, located at the middle of the remote. Press that button until the backlight is highlighted.
4. Press the right direction button until the backlight is at 100.
5. Press the OK button and then the Exit button until you get back to your picture.

My Vizio LCD TV screen fades to dark. Sound stays on.


I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.

change out the LVDS cable (the cable that go from the control board to the main board) and it should resolve your problem. If your TV is still in warranty, call 1-877-MY-VIZIO and they will set up an in home repair for free.

Picture is frozen


There is a button on the lower part of the remote that is a "freeze" button, it will freeze the picture, or capture a still shot. Try pressing this button to "unfreeze" your picture.
