Screen has blue tint - monitor problem ruled out

[Scorpio]

My computer's screen has a blue tint to it, i.e., the color red isn't being displayed. I've got a NVIDIA GeForce 6100 built into an EMachines computer.

It doesn't seem to be the monitor:

-I tried re-inserting the monitor's cable, checking for bent pins, and then trying a new cable - didn't work
-I hooked a new monitor up to the computer, it had the blue tint as well
-The monitor's built in menu to fiddle with the settings displays colors properly

I've tried this so far:

-I opened the case, cleaned it out, and looked for any glaring problems - didn't work
-In the device manager I disabled the NVIDIA 6100 Driver, the blue tint remains
-I installed new video drivers - didn't work either

Any ideas? Could it be the connector where the video cable plugs in on the computer? How do you check that?

Have you got another video card to try out? or your motherboard may have onboard video, just so you can try a different video source.

I'm going to try another video card today. I'll get a cheap one from somewhere and see if that solves the problem.

Is it possible that a pin is dirty or something? It really does sound like the symptom of the PC-to-monitor being plugged in slightly askew.

Sounds like a faulty cable to me.

I HAVE THE EXACT SAME PROBLEM! Same setup, eMachines Desktop w/ Nvidia 6100. Just now, heard like a bug flying around, then it turned blue. I have Vista. I'm going to try contacting eMachines Troubleshooting. Hopefully Acer didn't destroy that when they took over.

I found the cure. On your monitor (I have the stock 17" eMachines LCD), press the Menu button (On right side) and go down to 'Reset'. I did that and it went away. Hopefully it doesn't come back. I must add that before I pushed reset, I fiddled around with the color, making red, blue, and green all at 50.

Hi guys,
I have the exact same problem as scorpio. I also the exact same computer as him. Anybody have any suggestions as to what I can do. I opened up my computer and cleaned it out, but that didn't help. I know that my monitor is ok as it works with another laptop.

I tried what ZuneLarson did and it didn't fix the problem.

Any help would be appreciated.

If the card isn't built into the board, try pulling it out, cleaning up the connection, and re-seating it. It really is as easy to do as it sounds.

Every so often someone will send me a private message asking if I ever found out what the root of my blue-tint problem was, because they have the same issue and found this thread while researching it on google. I figured I may as well post an update.

In may case the issue turned out to be a faulty motherboard.

My final grasp was to install a new graphics card (the current one was built into the motherboard), but that didn't work out. A computer repair shop confirmed the motherboard was screwed up.

Just as a reminder, if your monitor has a blue tint these are some things you should rule out:

-monitor color settings accidentally changed (if the built in color adjusting display for the monitor shows all the colors properly, odds are the monitor is fine)
-Try disabling graphics card through device manager. See if anything changes.
-Try downloading new video drivers
-monitor not plugged in properly (see if the connection is loose)
-pins in monitor plug bent or dirty (try needle nose pliers)
-monitor cable faulty (try replacing it, or just jiggling it and unkinking it a bit)
-monitor itself faulty (try a new monitor with the computer. If the image is still blue, it's in the computer)
-Try cleaning out inside of computer / checking for obvious giant dust balls
-Try re-seating graphics card, if it's not built into the motherboard
-Graphic card faulty (try switching in a cheap one if you have one around)
-Motherboard faulty (Probably have to take it to an expert. If it's busted, accept bad luck, get new one, or maybe a new computer all together if the current one is older. Don't buy anything from eMachines ever again)

As a follow up to scorpio's response:

I took in my computer to a local repair store and they told me they thought the video card was starting to go. As it was an integrated video card, one solution was to replace the entire motherboard - which they said wasn't worth it as it would be as expensive as buying a new computer.

The other solution was to use a new video card that would plug into the computer - my motherboard had a PCI slot for this. They tried it and it worked. I bought a used video card from the store for just 30 bucks. The service cost about 30 bucks as well - so the total solution to this problem was only about $70.
