Try uninstalling and reinstalling the monitor drivers if any are applicable, run a direct X test on your hardware make sure your video card is OK. Try doing a wiggle test on the VGA cable that is plug ed into the back of your computer, that sends the signal to the monitor. Work your way from one end of the cable to the other, look at the monitor screen and see if there is any change in the color , if that don't do it its possible there could be a lose connection between the circuit board and the picture screen inside the monitor, unless your mechanically inclined and know some basics of electronics its recommended you don't do this and get some one who is qualified to do so, but if you are mechanically inclined and do know basics of electronics and if your feeling confident remove the power cord from the wall outlet, remove the power cord from the back of the monitor, shut down your computer and unplug it from the wall outlet, remove the VGA cable from your computer, examine where all the screws are that hold the housing from the monitor together put a white sheet on your bed and carefully and slowly split the housing which are the front and back of your monitor, in the center of the white sheet so if any screws fall out you'll see them on the sheet, when you pull the two halves apart, if it doesn't come apart don't force it study its body and check for more screws when you get them apart , before you touch anything inside the monitor touch a metal object some where in the room that has no electric or electronics on or with in it, to release any static electricity from you body once you do so and open the monitor check all connectors for looseness or any corrosion don't touch anything else but the connectors. if all is well and the problem still exist bring it to a repair shop or bye a new one go to EBay or try www.MicroCenter.com those are your cheapest places, unless money is no object.

My dell 1201 projectors displays only in yellow


you have most likely lost 2 of your color guns, most projectors have RED, Green and BLUE as the projector colors (some newer projectors have added a 4th color). if one of your color guns has gone out, you may experience colors that are not correct. that is where I would start. go to the convergence routine, in your setup menu. this is where you can determine if one of your "guns" has quit working.

We just received a big screen tv as a gift and we want to hook up our dvd player and our vcr and have lost the manuals. HELP


You can hook your dvd player in tv by using component video input terminal having green-red-blue colors for video signal and red-white for audio signal. so total 5 wires been used here. color order should be exact at both units, tv and dvd player i.e green to green, blue to blue and so on.

vcr can be hooked at composite video input in tv having 3 pins, yellow for video, red-white for audio in both units, vcr and tv. pins color should be exact on both units.

need further help, post here please.
