Just died on me recently. If I continously hit the TV/monitor button on the remote or TV while moving the mouse, the computer screen comes on for a second and then disappears. Weird. No TV whatsoever. I real piece of work this is to die after 4 years. Thoughts? Thank you.

This sounds like a common problem on these TVs (it's happened to both of my AOC TVs a couple times). Try a factory reset:
1. Press and hold "Menu" and "Channel+" on the TV. (do not use the remote) 2. Using the other hand, press the Power button. 3. A small screen should appear in the top left part of the screen. 4. Using the remote, select "Memory Recall" and Enter. 5. Power off and reboot the TV and Computer. 6. Run channel auto-scan to regain the picture.
Well, without knowing the exact model of tv and remote, I can just give my best guess. Try using the volume up/down on the TV and / or the remote. On the TV, try pressing both the volume up and down at the same time. Stick the remote right in the face of the TV (direct in front of the remote sensor) and hit the mute button. Try tapping the mute button in very short single bursts rather than pressing it for a half second like you would any other button. If any of those work, please come back and reply with the model of the TV and remote, because someone somewhere probably has the same issue and would love to have it solved!
Make sure your tv is on the right input first of all. The newer flat panel lcds combine the componenent video (red , blue, green) with the composite video and audio (yellow, red, white). If your tv is on the component input then you hear audio from the composite input since the audio inputs (red, white) are shared. Look for a source or tv input button on your remote or the tv itself and try pressing this button unti you see a picture with sound.
mine did the same thing...it was on rgb...didn't have ability to plug in computer to tv as suggested previously and I kept trying to hit input button on side of tv after turning tv on..didn't work but when I pushed input button before turning on tv when i turned on tv input screen was up and was able to move input to hdmi...everything works now.
Tried to use my TV as a computer monitor. When tries to boot up, will go to "No Signal". All hooked up correct. Is ther something I need to do tobe able to use the monitor with my computer. I have a Dell Desk Top Computer.
Using a monitor 1..connect computer/media center to your monitor, 2 click on nvidia nview display settings, 3, select the current display tab and samsung, 4 then apply, 5,then when the confirmation box appears click yes within 15 seconds.
Using your samsung. Attach a scart to your media centre, from your t.v with the p.c cable still attached, turn over using the source button until you can see a pc picture on your screen (EXT1or2), do steps 2 & 3 THEN move your cursor to the apply button (do not move the cursor from this position), press your source button till you get PC channel (which has no picture yet) then press your mouse button to apply, ( your picture will flicker on), and before the picture goes confirm with the yes button. You now have light! eureka :)
