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.
It would all depend on what type of cable you are useing to connect the dvd to the tv.With component cables if you have the blue input in the red or any of the three colors mixed up then it could cause a black n white picture also if you place normal a/v cables into the component slot then you also might get black n white have seen alot of people put the yellow cord into the green female slot of the component input of the tv instead of the video in slot. If you have HDMI an a blu ray make sure you got a high speed cable with at least a rate of 10.2 Gbps or faster should not result in black n white but you will not get the picture clarity u should be getting an it also may cause screen blur or drag on fast moving pictures
The series of the cable should go green red blue into the back. if you put the green in the red and the red into the green it give the TV a red base to go off of for the picture so everything is red. The reason the green cable won't is because it transmits a black and white picture which allows it a nice base to add the green and red to.
well if the light stays blue , that means its still on ...what you may need to do is go to your menue and select the setup selection and then go to tuning band.....i belive it will be on page 32 of you manual, under customising the setup settings....in order for the tv to start working it needs to be able to scan for channels.....if you are useing a cable company like comcast or direct tv...depending on how you pluged it into the tv ,(like using the input 1 or 2 , s-vidio, cable , ectra,)...you need to push the input button thats on the lower right side of your remote and select the propper input area as to how you hooked up your cable box
