Video blacking out...

Video will black out, but audio will remain. Input or source signal does not matter - it's blacked out on all. After leaving overnight, will work again but will undoubtedly fail and black out again. I'm guessing its the video power supply and have actually changed some of the capacitors already, but not all on the board with the high voltage unit. Will a change of all capacitors work?

Changing all the caps is not the right approach to problem solving.Works cold,but fails after hot is a thermal issue.After set warms up and fails,use cool freeze spray on suspect components to isolate.Determine whether CRT filaments are lit and/or if HV is present.Also,inspect jumper wire from transformer to HV block-if corroded,replace jumper HV lead & HV block w/Mits. parts.

Magnavox 15MF605T/17 only getting black and white

What is your TV source? If you are using the component input, check if you have two of the video signal wires mixed up between the source and the TV. I have gotten black and white when blue and green were swapped. If your source is over the air TV from a low-power NTSC station, you might see a black and white from a weak signal.

I hope this helps.

Ps3 plays in black and white with av composite cable

Some newer TVs do not have the traditional "yellow" video input, known as an "AV" connection. Even without that input, you should be able to use the standard three-color Wii AV Cable that came with the system.

What to Do:

Look for "component" inputs on your TV. These connections have a row of five differently-colored inputs (green, blue, and red for video, white and red for audio). If you have more than one set of component inputs, it's the first set that generally works with standard AV cables. Look for a set that has a green input with yellow around it, or the word "video" just above or below it.
Plug the yellow end of the Wii A/V cable into this green "Y" input. Plug the white end into the audio "L" and the red into the audio "R." Leave the blue and second red holes open.

Turn on your Wii console and set your television to the input select being used.
If you are seeing the image from the Wii in black and white, try the following to get the image in color:
- Cycle through your television's input channels (usually with the "Input Select" or "Source" button on your TV's remote control) to find the input select that has the image in color.
- If you're only finding the image in black and white, you may need to switch the setting of the input select from a component signal to a standard AV signal. This can be done by:
  - An on screen menu option. This is often accessed by using the "Menu" button on the remote.
  - A button on the remote that switches between the standard and component signals. These can be labeled such things as "AV" or "Video."

The tv on;y shows a small pip window in color if it is a large picture the picture is in black and white how to fix?

Whatever input video signal you're using, PIP should be in color. What are you using out of your dvd for the second video input source, composite or component? Composite you should always have color, Component, if you have a bad red or blue, and just the green is working, you will get black and white. The green is the luminence signal.

How can i play ps2 on lcd without having a black and white screen ? how can i connect the cables ?.....when i look at the back of my lcd i find three ports (red white yellow) when i use them the screen is...

1) The set of input (Yellow= Composite video, Red= Right channel audio, White= Left channel audio). This set of input is for composite video.

2) The set of input (Red= Red video signal, Green= Green video signal + sync, Blue= Blue signal, Red= Right channel audio, White = Left channel audio (the Red and White will be grouped close together). This set of input is used for Component video for HD signal.

You should try using composite video source (Yellow RCA jack) from DVD player and feed to the monitor and see if it works OK with all color showing that way we acn find out if it is the video source problem or the monitor video signal processing problem. Try the PS2 on the TV if it works OK also.

EasyCap - ''no input signal or signal is unclear'' Please Help!!!

In the ULead VideoStudio Application. Go to "Capture" tabbed panel. Select "Options" then "Video and Audio Capture Property Settings...". A window should pop up.

In the "Source" tabbed panel. Change the "Input Source" drop down menu to either "Video Composite" or "Video S-Video" depending on whether you are using the yellow or S-Video picture lead.
Change the "TV System" combo-box to PAL for colour and NTSC for black and white. On my computer S-Video option is showing black and white when using my Sky HD box, don't know why this is yet.
Try the above and you should get a picture. You can also change the frame rate and other compression techniques etc.
If it still doesn't work try changing your digital/sky/vcr/xbox picture settings to PAL for colour or others for picture preference.

Hope this helps.

Goodluck

I got dual (forj) headrests the sound works on the one that has the dvd in it but not the one that does not, the rca jacks are hooked up to it, it has speakers in it, does it even have sound?

The monitor only headrest does not have audio handling circuitry in it. the wire harness for that side is the one with the red and black wire, and the two video inputs, not the harness with the red and black wire and the three RCA jacks. It will function on the wrong harness, but it is not the correct one.

The DVD headrest has two harnesses. One of them is for power and output, the other is for input only from another source. The harness with the red and black wire has the three RCA outputs... the video lead goes to the other headrest, and the audio can be fed to an aux input on a stereo or amplifier. The input harness is designed to be Video 2 input from either a gaming system (a Game Cube is a nice option), or another DVD or video source (hand held video device such as iPod or Smart Phone like a HTC Touch Pro 2).

No picture

It sounds like the backlight is out. If you can see a faint image that changes then this is the case. You either need to send in for repair or replace. It can if you are lucky be a connection. You can try removing the video cable and try another source or cable.

First, have you doublechecked the video hookup? It sounds like you are using the video/audio inputs to the TV, so make sure you have VCR video out cabled to TV video input, and the TV source/input selection set to that input (video 1 etc.). If this checks out, check for a dirty video head on the VCR, though a dirty head usually results in a blank or blue video display (older VCRs, snow). You could do a process of elimination by hooking VCR to a different TV and see what is displayed then. Lastly, I assume you've tried multiple tapes, just in case a home recorded tape was incorrectly recorded?

My Mitsubishi WS-65869 tv has no picture but there is sound. There's an orange glow at the base of each of the bulbs, but the blue bulb does not appear to come on. The screen is black except for faint green and red lines. I've repaired the DM board recently, due to the blinking green light of death, and everything was fine. As I was watching the tv it scrolled briefly and then the screen went black.
