Help, 24" sun monitor not displaying any red color?

Those jacks you are plugging into on the HDTV are not composite inputs. They are component. The reason the color is not right is, you have to have a Red, Green and Blue connection.

The black and white picture from the 1 cable is because you are using a composite signal into a component green.

Big difference between a composite and a component signal. I hope this helps.

problem with the monitor Display cable. it is damaged.

Normally monitor will receive 3 colors red, green, Blue signals from CPU. If one cable i.e Red wire connection is missing in display cable which is connected to monitor, Red color image on monitor wil be replaced with other fade color.
So, need the replace the display cable or display connector!

Possibilities:
1. video-card gone bad;
2. video-cable gone bad;
3. video-cable not tightly-connected to CRT;
4. video-cable not tightly-connected to video-card;
5. "red" gun inside CRT gone bad.

Disconnect the video-cable from the computer, and try again to adjust the "red". If red-free, then it's time to responsibly recycle the CRT.

Reconnect & wiggle the video-cable, to see if that induces any "red" onto the CRT.

Connect the CRT to the VGA-output port on a notebook computer, to see if that video-card generates "red" as one of the primary colours.

Give the CRT a strong "whack" on the side, to see if "red" makes an appearance.

Mike,

I would recommend for you to try different monitor, so that you can isolate the problem.

If same problem occur, try to plug in your video card into another PCI slot in your computer. Cleaning the gold fingers of the video card with a clean cotton cloth might help.

Use a blower to remove some dust on the PCI slot.

Or try inserting the video card in another computer. If you get the same problem on another computer, you need to replace the card.

Good luck!

You probably have tried this, but make sure monitor is set to correct display... i.e., Analog or Digital

Also, try starting in safe mode and verify Monitor is able to handle the display settings resolution

Hello,

It could be a problem with the monitor cable.

Try unplugging and re-plugging the PC to monitor cable (VGA cable)

If possible, Use a different monitor to ensure that your video card is working fine.

Go to the setup menu on the LCD panel by pressing button 1 on the front. See if there is an option to reset the lcd to factory settings. Reset it and report if it helps not.

change display settings to 75hz

If all drivers are updated and you are positive monitor is ok then it must be the connection in between (video cable) or there is a slight chance the video card is gone bad.


I would try a new video cable first

Try reseating the video card in the slot on the board (take it out and put it back in)

Try the monitor on a different PC if possible with the same cable you are using on yours.

If monitor works fine on different pc and cable is good then also try different video card if possible (even if yours is not old) I’ve seen new cards suddenly have problems for various reasons everything from video cable had a little to much tension on it and the solder connections on the video card came loose all the way to the card just decided to quit working from some sort of defect so I wouldn’t rule out the possibility.

But the most common reason for the problem your having is usually loose connection on back of monitor or PC or bad video cable.
