Auto sensor finding wrong inputs, cant find good component signal
My TV started acting weird. It is problematic with finding odd inputs that aren't plugged in. For Example: Starting prompting for S-Video input, when I don't use S-Video. My biggest problem now, I have Component Video Input 1 through 3 set correctly. DVR, DVD, and XBOX 360. I know that all are producing picture, but for some reason, the TV sits on a "BLUE SCREEN" and I cant see any good picture. After some initial troubleshooting with connections to COMP 1 through 3, I decided to reset the TV, not the simple reset, but the main Factory Reset. Still having problems. At one point, it would sit there with a, "Green Box at the bottom of the screen, and the top 8 inches or so was a black bar. Green and Black.
Right now, it is just a blue screen and keeps shutting off saying that it cannot find a signal, when I have double check the cables, replaced the cables, and still no luck.

Re: Auto sensor finding wrong inputs, cant find good...
As any new technology TV as yours. your tv has a microcomputer (kind of mother board) that is not detecting your video inputs or any information to control. The initial set up cannot finish and there it go the answer: you have a blue screen or green with the bars (of course this is another area but still related with the control of video that it is another funtion af the main board). So the outside of the tv is ok now because you made many actions directed to troubleshoot conections, and there are fine, but the problem isn't there this problem is at the board level of the tv. technician is needed.

if auto channel scan finds nothing , then your tv isn't receiving a strong enough signal to display , and it will not go any further than that , you can though select another type input (hdmi ?) and after providing a proper signal to that input it should display that picture
Some of the older Mitsubishi with HD 1080 have only one component input for HD---it is marked on rear as DTV----also a model number may allow me to give another suggestion--Some of these sets (ws, wt, vs models) will on occasion lock out or disable the input/s.
Depending on model number most also have 3 hidden menus---one is the option menu----it allows with the Mitsubishi remote via a 4 digit number (by model number) to enter there and do a hard reset of the set----sets every setting back to factory original---seen it "cure" all kinds of odd problems from missing rear inputs, no sound, odd video issues---you name it.
Get me the model number and I will see if can find the code for yours--you can also try hooking first direct a 1080 blue ray or Dvd if you want to see if the input is active or not first.
It sounds like you aren't cycling fully. It sounds like you are on the TV (RF/Cable) input, then you switch input to Component 1 (for your DVD) and watch the DVD, then hit the input selector again, switching it to Component 2...you need to keep switching the input until you are back on the TV / Cable input.
Different video signals use different connections
...and we are speaking ONLY the video(NOT including the audio connections)
Composite Video (typically colored Yellow) uses 1 RCA connection on your TV
Svideo (uses 1 svideo connector on your TV) a circular connector with 4 pins in it
Component Video (typically colored Red/Green/Blue) uses 3 RCA connections on your TV
These are the common analog video signals....You cannot mix and match these and plug a composite (Sometimes called AV in menus) into component etc
If both your sources (wii/DVD) you want to use a component signal to your TV (which BTW is the best quality of the 3 I listed) you will need 2 component inputs on your TV
run it through a high end receiver (that will act as your switcher)
buy a small stand alone switcher, something like:
settle for a lower quality DVD signal and use the Composite video out (yellow jack) into the Composite Video In on the TV and use the component for wii
This kind of tv u must have cable or satalite tvs pay broadcasting signal cable,so u have a box .Tv have HDMI ports or RCA AV component cable input?The incomming broadcating tv signal go to the cable or satalite boxes.Than u use a HDMI cable or RCA AV component cable go through those boxes than to ur tv HDMI input ports or RCA AV component cable input holes.
The TV must be tuned to the correct input also. Please cycle through the tv inputs by pressing the input button on the tv one time, then wait 5 to 10 seconds for the tv to recognize the input signal. If nothing, press again. You don't say which tv you have but many newer models have 5 to 7 input sources you will have to cycle through to find your signal.
With out more information, this is just one step in finding out what could be wrong. Please rank me accordingly.
I had the same problem, so i contacted panasonic, I am including the email they sent me.
For connections of audio, so that you can hear all tv audio through the surround system, connect either an optical audio cable or red & white analog audio cables from the tv to the home theater. If you are using optical audio, there is a plug on back of tv labeled for digital audio output and an input on the surround sound system. If you plan on using analog red and white, use the PROG OUT red and white output jacks on the back of the tv to the AUX input on the home theater.
For video connections, to get HD you will need to be using either HDMI or Component cables. HDMI is the cable that will provided 1080p signal (the best HD signal), but if the source does not output 1080p, then your tv will not display 1080p. Most cable boxes output at 1080i or 720p when on HD stations. This signal still provides great picture quality, but HDMI is not needed to get these HD signals. You can use component cables for your cable box and the DVD player output to the tv for video. HDMI might give you a slightly better picture quality but the signal will be the same.
To make the connection, you will want to connect from the cable box to the tv (component or hdmi). Also from the home theater system to the tv using hdmi or the video cables from component (red, blue, & green cables).
Yes, I seem to have fixed the problem on my Akai using some creative google finds. One of two things worked - not sure which:
1. Leave the set unplugged overnight - it must let the electronics reset when the residual charges clear
2. For my Akai (remotes and models vary), hit in remote's sequence quickly - brightness, freeze, menu, enter - this places you in some screen that offers a hard reset option. That didn't work right away, but i did it before the option above and then the set worked again.
My problem was really odd because it worked for the component inputs and you could see the video and TV signals inside the PIP windows, but not full screen as primary input. Why the TV could 'see' the signals in a PIP windows but not detect them as primary I have no idea.
Hey! I have the same problem as you. But! this would happen only when I got a power outage. Unplug the TV for a couple of minutesand all was fine. For the last 5 day I have no TV. I have tried everything. All the out on the TV and I still get unusable signal. My rep told me to unplug for 24 Hours. Still didn't work. My menu option work as well and every time I put the TV on, off or if I change the input sound will come on for 2 seconde and stop. If I find the salution I will let you know.
