Re: Color Problem:

In Monitor CRT Red-Blue-green cathode guns are there.. Mixing of these colour we can get the original colour chrominace technique. if any of the colour gun is faulty we would get more REad or blue or green picture. Measure RGB voltages. you can verfify which gun is faulty. if then check RGB processing circuits. Else there might be problem Chrominance colour decoder system. Contact service centre

Hcl crt color 15" digital color is

Unfortunately, this is not a fixable problem. Samsung CRT monitors are well known for losing color; they have defective cathode ray tubes. I recommend that you buy an lcd screen. sorry if that wasn't what you wanted to hear! don't forget to rate

Redless screen

If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's and CRT monitors are very hazardous to service. Even when plugged out, they can store very high, deadly voltages. How old is the picture tube? If there's lots of phosphor burn on it, chances are the red gun inside the picture tube is out. A sure-fire way requires an oscilloscope. Check the voltages on the three color guns at their corresponding pins on the CRT's neck board. You can see their levels change as you tweak their adjustment pots on the neck board. If the red voltage is present and at the same levels as green and blue, then the gun inside the tube is shot. If the red voltage is NOT there, then you can work backwards and find out where you're losing it. It could be a bad buffer amplifier (transistor or I.C.), bad solder joint, or even a broken wire in the cable harness. check for cracked solder joints where the RGB, Grd Sync connector is. check the pins on the molex power supply connector, could be that the pin for the red is pushed back and is not making contact. Try swapping the red and green inputs if you see red on your monitor and no green, then it is NOT the tube. If you see no red still but still get a green where red should be I would suspect a bad chassis.
