The picture looks very blue even though I try to reduce through HUE adjustment -- when flipping through other video source, the source has no signal but the blue background stays on ( previously is back background ) it's the same blue background that if a sony dvd/vcr video source turns ON -- open up the tv, the blue lamp never seem to be OFF

There is most likely a missing connection on the cable, so unplug the cable from your computer and the monitor (if you can) and make sure that none of the pins are bent or look pushed back into the plug. if they do than you can try to adjust them back to strait and flush or take the cable in to your local electronics store and tell them that you need a new one, they will help you with that. or you can mess with the display settings, usually a button on the front. in those settings you will be looking for the color options and it will either give you presets or let you choose a custom setting, if you have a custom option there should be a blue slider that you can adjust to fix the blue hue.

The most common problem I have seen with these Samsung projo units is the blue CRT (picture tube) failing. They usually form algae on the face of the CRT which means replacement of the CRT or rebuilding it by a CRT rebuilding company. I wouldn't suggest the novice to pull the CRT out because if the wrong mouting screws are pulled you will spill out the cooling fluid within the face of the CRT and that will cause more problems.
