Select the input channel for your Fire TV - Turn on your TV and select the input channel for the HDMI port you used to connect your Fire TV. You should then see a loading screen with the Amazon Fire TV logo 4.
If blue when connections are made to rear inputs also it means it is not the tuner in the set---a good idea is to hook a DVD up, turn it on and then the set--select that input with the DVD already on--
That aside you may want to make the effort to call Vizio and see if this is a known issue or if a software upgrade is available for this issue.
If I had to "guess" it will be the main board that processes all signal inside the set.
Do some research with GOOGLE by model number "known problems" blue screen only etc.
This is blue ray lens failure. this opticalAssembly has two separate reading lenses. there is one designated for Cd audio and CD_ROM reading and, the other is blue ray compatible. the blue ray lens in inoperable at this point. you will need to replace this lens assembly.
my tv just went to a blue screen one day. I can turn it on and then it will just remain on the blue screen. Any button (except the volume) I push on the remote comes up on the screen "no signal". What would you suggest? I have been reading about replacing a fuse or board? Most of those are on the 42 inch version---I have teh 37 inch version.
Many (not all) sets will give you the 'blue screen of death' (just like a crashed Windows installation but with even less information) if they have no signal input.
You didn't mention where your TV signal comes from; antenna, cable or satellite box and how it is routed.
DVD players normally put some kind of logo on the screen while they are trying to read a disc so the screen shouldn't be totally empty unless the player has failed altogether.
I'd recheck cables for seating and if you have another TV set of some kind, check to see if you are getting any signal for the set to see.
Well make sure it's on the right source, I have a 50 inch Samsung and when you're on the wrong channel it'll read no signal and you can't do anything. So make sure you have cable hooked up right and make sure it's on the right source or video channel first. I don't know but this might help.
The RF input is the correct one for a cable signal. The other sources use the RCA and other ports which you can connect to other devices, like DVD or VCR players.
If the humm noise only happens when you're on the TV channel then it's likely just the station. Try changing the channel and see if that helps, and make sure the coax is screwed in all the way. Also make sure the other end, if connected to a VCR or other stuff, is tightly attached. If you share cable with many other people and the signal has snow (white spots on the TV), then you may need to buy an RF signal amplifier to reduce the noise.
Source changes the input (RCA versus coaxial versus component inputs), change the channel for different channels..
