Question about ViewSonic N4785p 47 in. LCD TV
A problem like this can be caused by RF interference. Shut it all down again and move the converter, any cordless or cell phones, wireless PC's, routers, etc. so nothing is within 3 feet of your set. A poor ground on your converter can also cause RF interference. Make sure you have a grounded plug going to it, and it is connected to a grounded wall outlet....likewise for your set....and by no means have it near a microwave oven!
