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.

Any ideas?

    I have same problem with WS65813. Didn't have problem untill we moved.Have checked Connections and reconfigured.No help. All other tv functions seem to work fine. Just no picture and a blue screen with no signal error message. Will play for about 20 mins before it blue screens. Turn it off and then back on sometimes brings it back.

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.

Cant get past auto scan


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

My mitsubishi medallion hd 1080 doesn't show content from component cable


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.

Have a 36 inch vizio flat screen it started about four days ago.When i switch from watching a movie on DVd back to regular picture on component 2 no picture is coming up tried chanel 3 an d4 still no...


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.

I have a 32" flatscreen


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
OR
run it through a high end receiver (that will act as your switcher)
OR
buy a small stand alone switcher, something like: http://www.amazon.com/4X1-HD-Component-Av-Selector/dp/B000BVIBGI/ref=pd_sim_sbs_e_4

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

I hope this helps,
Magoo

No picture with Yamaha 6130 reciever. have


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.

Good luck.

Cant get my viera linked panasonic to play through surround sound


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).

We hope this information is helpful to you.

Thank You,

AUTO SIGNAL DETECTING NO SIGNAL


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.

"weak signal" on my RCA scenium


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. Gilles Ottawa
