This is more of a provider problem. Report the signal problems to the service you subscribe to for tv.

LCD TV Has Sound, Backlights Work, but No Picture


I have been having the same problem with my LG. people say there are bad capacitors on the power supply board. I don't have the know how to replace them and don't have the money to pay. I can get mine to work by blowing hot air with a hair dryer into the back of my tv through the vents over the board. Heat it up for a couple minutes and turn it off and then back on and the picture comes back. I just never turn the set off now.

TV Will Not Start Occasionally


Sounds like this unit is still in warranty. Have the service people come out and look at it. If you don't have a bill of sale, you should still have production dates on the unit.

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.
