My sony 42" flat panel monitor is used as a television set using ths S-video cable as a connection. When you turn it on a few minutes later it begins shutting off and on by itself. sometimes the picture finally comes back on and other times I shut it off for a while and it doesn't do it again.

I get that there is no Chroma on something but not sure in what mode or source you are speaking about. Sometimes people have trouble due to a setting being wrong or they use a really cheap video cable which can strip the higher frequency Chroma signal off of the Baseband or Composite video signal. Try a higher grade of video cable- video signals at 10MHz bandwidth do not like to go through cheap audio cables. maybe you could clarify the problem more?
This can occur due to many reasons...the simplest of those is... Damaged monitor signal cable...results in improper signal transmission Also check if ths is a problem with the monitor or VGA card...Just connect it to another computer...If it works then its VGA card problem otherwise its a monitor problem.If you are good in electronics then the problem is 1)You have the typical convergence failure of the convergence correction IC's which need to be replaced
2)Cpacitors on the CRT are damaged and need to be replaced..
If you are not familiar with electronics pls dont attempt a repair as it is a high voltage device and the risk of electric shock wil be high.Just drop into a service center if this is the case
There is some color format mismatch. Look for settings and try to correct it. You may go through the operation manuals of both step by step. Also check whether the frequency of the device is same like both are of 50Hz or 60Hz.
Assuming your laptop has an S Video output you would connect it to the S Video input of the television with an S video cable. Before doing so you should have turned the resolution on your laptop down as far as it will go. I believe the proper S Video resolution is 640 x 480. You can find an extensive resolutions list here http://en.wikipedia.org/wiki/List_of_common_resolutions
After setting the laptop at the resolution you're going to try you should turn it off (not restart it; actually turn it off). Now connect the S Video cable between the television and the laptop and turn the television on first before the laptop. Turn the laptop on and switch the television to the proper video input. Hold down the function (fn) button on the laptop and the dual monitor key (usually f5 or f8) for about 15 seconds or longer until you get an image on the television screen.
Someone told me to use the settings in the "graphics tab" (for multiple monitors) not the settings in the "properties tab". Both allow multiple monitor configurations. Two minutes later and high have a 42" LCD HD monitor!
Back again. It appears that the key is the order in which you connect things and switch the TV on or off. It took some experimenting to get to what's reliable. I'll spare you the details and confine myself to what works. 1. Start with the monitor cable disconnected at the laptop. 2. Turn on the TV with the source set to your regular satellite (or cable) signal. 3. With the laptop on, plug the monitor cable into it. 4. Switch the source (at the TV) to receive the VGA signal (from the laptop). Voila! To turn off, reverse the procedure.
Turn everything off and disconnect from mains. Wait a few minutes. Disconnect HDMI cable. Turn on TV and DVD. Connect cable. If this does not work use a cable of different spec. I had the same problem and now mine works . Good luck. T.P.
