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.

I would suspect the quality of component converter device...
HDMI is the latest state of the art for HD (High Definition 1080) video signal. Poor cables or poor connectors can cause weird results.
It's best to go from HDMI to HDMI.
If the tv doesn't have a HDMI input then it probably can't handle the newer standard.
Component Video is an old standard for video before we got high definition. It uses three separate wires.
Try swapping the coloured wires around to see the result.
If the model is correct it has a series of 3 hidden menus--one is the option menu--it is a hard reset of entire set except convergence to factory original---It is called the "option" menu and is used to cure all sorts of odd issues.
It requires the use of an original MItsubishi remote and a 4 digit code.
If you want to try it let me know and confirm model number.
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.
try different type inputs on your TV- HDMI, component, composite
then look in the menu of your DVD player- with no disc in it- find "setup menu" then find "video output format"- select the one you are using on the TV, the options will be HDMI, YpBpr (component) , video out (composite)
lets start with the easiest first.does your tv in the menu option offer an input output source like 720p or 480p?on my set i can change to any format.maybe yours does too.let me know and we go from there.
dont try to look into the channel in finding the signal (audio/video). you need to change the input source of your TV. check whether you connect it to AV1, AV2 , AV3 then choose the right input source in your TV. good luck
Use your input/source select button. Should display input 1,2,3,4 comp 1, comp2 etc in order then repeat. Make sure your using the correct component input. Most sets have 2. Turn on the device first so you'll know your there when you see the picture
I started back in the day of tubes. A family would have one set and it would be a 19" black and white.
There are different resolutions now.
The components probably do work, but, they don't pass the 480i signal. The satelite converter's analog signal needs to be set to 480p and the DVD needs to be set to progressive if it does have that setting. If the DVD is not a progressive scan DVD, then, the only inputs that it will show on is the analog signal.
Some of the dish converters have a switch on the face for changing the resolution.
If yours doesn't then put it in an analog source and go to the menu and change it there. Then move it to the component input.
Hope this helps.
