The picture and sound were OK last night but when turned on again this morning only gave a black screen . Seems all functions are working with remote. Have disconnected all sound system components. I do get a flash of lines at the bottom of screen at switch on but nothing after that. Have only had set for just over a week.

Re: Black screen only on new LCD
Sounds like the video board when bad. I would say the TV went defective. Use the 90 day warranty to exchange for a new one.
Always use warranty at this point because the newer TV coming out in these days have very lame warranty.

My 47" LCD Smart T.V. was working fine last night. I got up this morning and I have sound but no picture. The VIZIO icon lights up as usual but I get no picture, only sound. From the time I turned it on, nothing appeared on the screen. I have already tried unplugging it for a while and still nothing.
