Video-cards generate "primary" colours (red, green, blue), and "mix" those colours to produce millions of "secondary" colours.

First, try replacing the "data' cable between the LCD and the video-card.

Second, if your LCD works correctly when connected to some other desktop or laptop computer, then the video-card in your computer is not working properly -- not sending one of the "primary" colours to the LCD. Replace the video-card.

Why did my computer monitor stop showing an image?


Disconnect it from computer and power. wait 15 minutes and plug only the power back in, press the power on button. The monitor may display a message that there is no signal or something like that. If that happens the problem is either the cable or the computer. If you get no message then look for the menu button and press it to see if any thing appears. If not find the manual on line and read it. Many times monitors get over-driven by computers to the point that they can't display OR they self destruct.


OR

Another way is to just unplug everything computer and monitor for 15 minutes. Plug in monitor first then plug in computer and press the power button, the display should display the booting information if the cable is good and the monitor is good.

Samtron 55e computer desktop,monitor screen is pink and then with the blue coded plug that goes in back of tower is on it turns black and then when i take the blue colored coded plug out the screen turns...


Samtron (a former subsidiary of Samsung) as an entity no longer exists, and I have been unable to find any legitimate links to archived support documentation.

The symptoms you describe indicate that the monitor has failed. One way to verify this is to connect another, known good monitor to the same output on your computer. If that other monitor works, then yours does not and it is not the computer's output that is bad.

Looks like time for a new monitor.

Hope that's helpful.

Montior screen is half shaded and half bright


Do this to check if your monitor is in working state or not...!

Step 1:- Turn on your computer.
Step 2:- Unplug the Video Cable of your monitor which is connected with the computer.

( Video cable:- Cable going from the back of your monitor to the back of your tower. It has a plug with two screws on the plug ends, which you can unscrew to unplug it. Thats how it looks like. Some times it is in grey in color some times in blue.)

Step 3:- Now check on your monitor. If the display says " No Input Signal " :- your monitor is fine. Some thing wrong with the computer graphics.
If there is not display and the monitor light is blinking or solid the monitor has gone bad.

( Note :- Remember when you unplug the video cable do not unplug the power cable of the monitor. )

Let me know if it helps.

If it is a Picturetube monitor, the blue/ yello/ green cathod might have lost.
If they are showing ok then you can adjust your Monitor Data Cable, if needed if may need to replaced. The major probablity here is showing as Data Supply Cable for Monitor needs to be changed, i could help more if i had more details about the problem.

HP w2007 monitor will not turn on. When unplugged and re-plugged (power cord) the little blue light in the on-off button flashes once, then nothing. The blue light in the pwer button remains unlit, and...


The only troubleshooting step I can offer here, is unplug it, and press the power button down for about 15-20 seconds, to flush any trickle power remaining in the unit. Then plug it back in, hook it up and try turning it on again. If this solves it, great! If it doesn't though, then I would check either with HP directly or with your place of purchase to see if your issue can be covered under limited/extended warranty. If you are out of warranty though, LCD repairs tend to jump pretty high, and usually end up being more than what the monitor is worth, so it may be more economical to replace it at that stage.

Blue tint on computer display monitor


Try
1. Unplugging the video cord from the back of the computer (and screen if it comes off) and plugging it back in. Sometimes it can become loose and cause a screen to have a abnormal color contrast
2. Updating the drivers to your card
3. Trying a different monitor on the computer. Mind you, if you plug in a differant monitor and the color stays the same. Check the videocards pins on the back of the card. I dont know if you gave all the info on how it became like this, so maybe it got undone and plugged back in forcably and one of them got bent? I
Also if the pigment goes away. Plug the normal one back in and if its gone, great!, if its back. Try the OSD settings on that monitor. Still no luck. The monitor is junk.

Hope that helps

What is the green plug at the back of the monitor that connects to the green plug between the pink and blue port at the back of the tower panel on a Compaq Presario is it the sound?


the pink is for a microphone and the blue is for a "line in" (much like a microphone). the Green plug is for your speakers. your monitor would only have this plug if it has built on speakers.
