When hooking up our 42L to a direct TV cable box via the standard coax, the picture is terrible with green lines filling in all the dark places. I then unhooked the coax and used a set of audio / visual cables. It worked fine for a while then went green again. This morning the picture is OK.. but I am afraid it will not last. Advice?

This is a very common Ground loop problem. The quick cure is to put a 2 prong to 3 prong adapter on the plugs which effectivly removes the ground from the circuit and stops your lines. Have fixed over a hundred TV's since the 60's that way.

turn your tv to channel 3 and then try 4 one of these should work . Also make sure that you have it plugged in the right coax jack in the back

The audio board on your 47" Vizio has gone bad. Replace that board will fix the problem.

SOURCE: 17 month old set; Picture gone. Direst TV repairman says it's the backlight bulb. Others say it's a Board.

it might be inverter board it is not backlight bulb according to my expertise bcoz once it goes off it dont come back

but u see inverter and CCFL backlight bulb failing symptoms are so same that u cant simply distinguish but i am sure u have one of these two problems inverter is more chance

Kindly rate me well
