Check if the remote is in TV position, that is, because most of the remote controllers have the feature that you can program them for use with another devices. Make shure that one button that says "TV" in pressed and released once before you try to change any function on the TV.

This is NOT an electrical issue. Anyone who is half handy with their hands can easily fix this.
I had this issue for awhile, and I just figured it out. There is a plastic strip that cover the the buttons on the tv. They want you to think it is a touch panel, but it isn't. Anyway it is glued on, not screwed or attached in any other way. The reason it keeps changing the source is because the glue expands when it heats up, and causes to source button to be pressed. There are several ways to fix this. You can remove the strip which is long about the length of the tv. Stick a knife or screwdriver under one end and slowly pull it off. Problem is solved, but it makes the screen look ugly. The way to fix this is by using a razor or knife and cutting off the glue (which is really tape) under where the buttons are. You can replace it with better glue, or just eliminate the glue from under the buttons and keep the glue on both ends, so you can re-attach it to the tv.

You may need to set up the video card to see the TV so you can display the computer on it.Somewhere in the setting for your video card should be settings for that.

Dod you use HOTKEYS on the laptop to tell it to send the signal the VGA outlet of the laptop? The hotkeys function can be set to turn off the laptop screen and only have external monitor to be the only display or it can be set to have both of them on.

'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:
Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!
Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.
Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.
If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)
