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 monitor.red 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

The picture of my Funai 28D-3728 TV is a bit over colored in red. The color balance is correct (I mean no specific zones of screen where this effect is realized (e.g in the corners or in the center)) but...


This is not user adjustable.
The problem is in the R G B circuit. Thr Red gun circuit is totally on!
If this is transistor driven circuit replace the transistor. The component
mostly mounted on the small PCB on the picture tube neck.

Hitachi RP CRT Gone Red On All Inputs!!!


I want you to do a simple visual check of something that will tell me what the problem may be.

Go to a channel that is in black and white--old movie and tell me what color the screen/picture is.

You can also turn the COLOR in the customer menu all the way off and look that way.

What we are trying to see here is if TRACKING is set correctly or has changed. If the screen is somewhat to medium reddish it may be an adjustment outside of the customer menu.

Let me know what you find--I have seen several of these where the black and white picture was somewhat red--the idea is it should be as close to black and white as possible--if red is the predominant background color the picture will look reddish.

If this has helped and you confirm the red instead of black and white picture--I can tell you a easy way to adjust this.

If this information told you something you did not know and helps you rate this solution as I do this here for free.

Screen


What you may have needed to do was adjust the green & blue crt screens to match the red. Go into your picture menu adjust, turn color all the way down to a black & white px. Now adjust each crt screen so that you end up with a true black & white px. Then adjust each focus control to get a sharp px, have your tv on a channel like the home shopping network so you can adjust each crt focus one at a time for clarity by cover the other 2 up. Then go back into picure adjust & turn color ahlf way up, you should see a better px.

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.
