HDMI untunable alert

Do you have an antenna connected? Otherwise, if cable, channel 4 is probably the one your cable box uses to send its channels to your TV from the cable box. IF you have HDMI output on the cable box and your TV (input), you just need to use that cable and choose HDMI from your input list.

What channel? Do you have a cable box from a provider? If yes, then the HDMI output from the cable box will go to one of the numbered HDMI inputs of the tv. Use your tv remote to select the correct input (source button) and when you find the corresponding numbered HDMI input, your signal should be there. If you are not using a converter box and your signal comes in from your wall to your tv then you must go into the menu settings of the tv and select a channel search. Usually an "automatic search" will do .Click that and allow for all the channels to be scanned. You will be limited to how many channels the tv will allow. If you know the cable signal has channels 1-200 but your tv can only "detect" channels 1-165, then you will be short 35 channels. Only way to to get more is to get a converter box. The only time you should be choosing a channel (3 or 4) to view cable on the tv is if the cable signal is going through a vcr first and then to the tv

ok a bit confused, Tuner ? like amplifier or Tv Tuner ? regardless seems like a easy fix .

First your cable box as 3 cables:1st . Power cable to outlet
2nd. From the wall ( usually a Coaxial cable coming from outside box ) into cable box.3rd. HDMI or Second coaxial cable ( One of these usually goes to the back or side of your Tv depending where inputs are located.)
Now Dvd has 2 cables 1st to Power2nd. To TV ( Hdmi or Coaxial )
On the back of your Tv will have 2-3 HDMI inputs . Assign 1HDMI jack to each media your trying to use.In this case TV HDMI 1, HDMI 2 DVD.
Assigning HDMI's will now reflect on your TV menu selection. Choosing HDMi 1 or HDMI2 from Tv menu will allow you use or view desired Media option in this case DVD or TV.
Now if there is Amplifier / Tuner involved like to connect surround sound to, connection may be a bit trickier however same principal.Plug all media into HDMI 1, HDMI 2, respectively,this time to the back of the tuner NOT to back of TV.Once you have done that You will need a third HDMI cable now from the back of the Tuner ( output Jack, usually has lighter color markings indicating Output HDMI) to your HDMI 1 jack in the back of your TV. Now you have bridge TV/ Cable , DVD into Receiver / Tuner and Selecting media will now be done not through TV Menu as before but through Tuner / Receiver menu or selection.
Good luck .

Good Luck

There are two ways to connect it. You can connect it to the rf connector with a coax (like a water hose) cable or with an RCA (yellow, white, red [preferred method]) cable. Then depending on which one of the choices you made you'll have to switch the television over using the TV/Video button. Before you press that button though make sure you have the converter box plugged in and turned on so you'll see it's screen when you're flipping video inputs. If you choose the rf connector method you will have to be on channel 3. You'll be able to tell when you get to the fuzzy screen where you can press 03 to turn to channel 3. If you chose the RCA method then you'll have to choose video 1 or video 2 etc. whichever one you connected the cables to.

it depends on how its connected to the cable box
Coaxial (regular cable wire only) channel 3 or 4
RCA Jacks (Yellow, red & white plugs) check the back of the tv for the connection usually Video 1
Component cables ( 5 wires) Component 1, or colorstream on older models
HDMI HDMI 1

The manual is telling you that your "source", whatever you are connecting to a particular HDMI port, needs to be turned-on in order for the TV to detect it. Make sure that the HDMI cable plugged into the correct HDMI port for each device (TV & cable box) and that the cable box is on. Does the cable box HDMI port need to be selected in order for it to be functional or is it on all of the time? Check your cable box instruction manual for details on the proper way to enable (turn-on) or disable the various outputs if needed.

Let me know if you need additional info.

Hi there,
I am having a similar problem with the inputs. I have a cable box plugged in to cable antenna, DVD to video 6 using HDMI, Mac computer plugged in to video 7 - using HDMI (TV does not recognize this) and then Nintendo Wii hooked up to Video 1. My problem is that Sony only realizes 2 additional components like the video 1 (wii) and DVD on video 6, it does not play the other components. I have to niw manually switch the cables to have them work...

The on timer will only work for a channel on this model not for any other inputs
