Electricity went out several times yesterday now the computer has lost many colors. Lost Red and several others. NEED HELP, Thanks
My guess is a video card problem. You might reinstall video drivers.
Wow, that’s a new one on me.
go into monitors onscreen menu and find factory reset or factory PREset and push that.
After you get this fixed, buy a cheap UPS.
Even if it only holds power for 30 seconds, it will save your equipment from the “blips”.
What kind of TV is it? Make model...how old?
excuse me..what type monitor?
make sure cables are tight and pushed in all the way...
You didn't think it might have been a good idea to shut the computer off after losing power more then a few times?? WOW
Here is what I would do. POWER THE COMPUTER OFF AND THEN UNPLUG IT. Then check the video cable on the back of the computer and on the back of the monitor. Make sure they are plugged in securely. Then power everything back on.
Usually color problems (everything has an odd tint) are caused by a loose or bad cable. What happens is that with older, analog video connection (not DVI, the older VGA connector), the video is sent as separate Red, Green, and Blue signals. When the cable is loose (or bad), one or more of these signals doesn’t get sent properly. You still see the picture, but the color is off because you’re missing one or more components.
Didn’t work..
Use this as an excuse to get your wife to allow you to buy a new monitor.
Good luck!
After a power outage, the motherboard connected to the video card needs to be reset. Unplug the computer and push the power button for about a minute before you plug it back in. If that doesn’t work, you may need a new monitor.
Find a friend or relative that will lend you a monitor temporarily, and plug it into your computer.
If your reds (and yellows and magentas) and come back, you need a new monitor. If the reds are still gone, you need a new video card.
Most computers have the video driver right on the computer motherboard. You can tell this by looking at where you plug in your monitor on the back of your computer. If the active plug is next to the USB, keyboard, and mouse plugs, it's on the motherboard. If the plug is on one of the expansion cards, you have a separate monitor board.
Buy an inexpensive new video card, and install it. Video cards shouldn't cost more than $25, unless you go for a high end graphics processor for gaming.
As usually you guys are the best. Your advice worked. Turned off computer and check all connections. Got GOOD color now. THANKS
I vote for Scutter’s advice in #10.
If it doesn’t work, open the machine up and re-seat the video card (pull it out, push it back in), and if that doesn’t work re-install the drivers as a last resort. If that doesn’t work then chances are good that your monitor got damaged by the power surge — which would be really bad luck and unlikely.
I’d say Scutter’s advice will fix it 9 times out of 10.
If
you have lost your colors that usually indicative of a blown CRT.It looks like your in need of a new one.
Get your self a flat screen monitor and you won’t have too worry about that again for quite a while.
I had that happen to my Sony Trinatron monitor.I noticed that all I could get was green and blue,the red color gun inthe monitor blew and that was it.
