  • saulrich Jul 17, 2008

    we have not changed the resolution on the computer. The monitor worked fine with it for 3 years and just started cycling colors. May just be time for a new monitor.

If available, try a different monitor. If the different monitor works properly, then it sounds like your monitor is just worn out.

The computer may be outputting an unsupported resolution. Attach the other monitor and change the screen resolution to something lower (800x600 or 1024x768) To do this, right click on the desktop, select "properties", go to the settings tab, and drag the "screen resolution" slider to the left. Press "advanced" and go to the "monitor" tab, set the refresh rate to 60hz if it's not already there. Press OK, Apply, then press "yes" to keep settings. Now attach the other monitor and see if it works.

    Try my solution before assuming the monitor is bad. Sometimes a windows update can change the resolution or refresh rate, especially if the graphics driver is updated.

    Good call. CRTs give you eyeball cancer anyway.

This can be a problem with the video card or the monitor itself:
Things that you can try:
1.Try to connect the monitor to another CPU and check if it will also have the same problem to conclude the monitor is bad
2.If *********** has a built in video card try connecting the monitor to it asuming that you have installed a additional video card and if *********** board has a built in video on it, because if the monitor work to the built in video the problem is the video card so you can have it replace.

Hope that helps.......

I think the problem is in your graphic card.
If you have another monitor try to connect it, if that monitor do the same then you have the problems in your graphic card.

I have an hp pavilion a720n desktop with an hp pavilion mx70 monitor and windows xp home. There is a problem with the color displayed on the monitor. I see mainly black and white, but blue shows up fine....


First of all you can check the computer by connecting another monitor to it to see if the problem goes away...if so then the problem would be in the monitor. If not , then I would try to change the video grafics card in the computer(assuming you don't have built in video). If you have built in video on the mother board then you will either need to replace the motherboard or disable the onboard video and install a video card

My dell inspiron 530 shows a block with red, white, green, and read, can't get to the my programs????


That "red white green and blue" block is a color pattern tester. that means the monitor is on, but is not receiving a signal, so its running tests. If your monitor has Digital input and VGA input, you may just need to switch inputs. Look for 1 or VGA if youre using the blue hook up. look for 2 or digital or dvi if youre using the larger white hook up. Some monitors also have 'auto detect'. If you are in "auto detect' bbut the color box is still there, then your monitor is not receiving video signal from the computer. It could indicate a bad cable or no signal being sent by the machine. If you try another monitor, you can see if the machine is working. I would try a monitor setting for VGA-1 first, since thats most common.

Tv cuts on for a few seconds and right back off on its own


We had a Sony LCD burn out and display the exact same behavior. You have to isolate if your cable box/pc is even involved or if it's a power supply/backlit bulb issue or similar.

The way you test a Sony is to disconnect ALL cables except the power, power the monitor up and hit the Menu button to display the test pattern (it's a small box with some color bars with NO SIGNAL on the bottom since there are no cables connected). After a few seconds, this test pattern would also go black even though the green light on the LCD was on. So it was the LCD itself that was blown and nothing to do with the PC.

I'd see if your LCD has some sort of test pattern or test mode you can access in the menu's with no cables hooked up to see if it can hold that pattern for more than a few seconds before going blank. If not, it would be indicative of a burned-out or blown LCD rather than the box that is supplying the signal.

Hp lcd f1532 h


This can happen if the minus button which happens to also be the auto image-adjust button is effectively grounded due to some internal fault or
if the switch itself has got jammed internally. In this case, if video signal is present, the motitor reproduces the image but continuously displays "adjusting" as osd message. If video signal is missing, the monitor cycles through solid colors in the black, red, green, blue, white sequence. I think this is part of the hp f1532 design to help the service
engineer( though I have not found any reference to it in official documentation yet). In this special case( minus button grounded), the
menu button is ignored by the monitor.

Main screen only has three boxes BGR


The monitor is telling you it's not getting a signal from the computer. The message is displayed to show the monitor is on and can display an image, but the computer is not sending video. Probably the computer is not starting up, or there has been a failure of the video card. You'll need to check into the cause.

Color problem


There are three Cathod Ray guns responsible for the millions of colors.All colors are produced by mixing the three basic colors namely Red Green and Blue (RGB) at suitable proportion. If any one of the three guns fail firing then we get improper colors. This can be rectified by
(1) hitting the monitor at the back by keeping it on a pillow the screen facing down - it will reolve the problem if the failure is due to the loosening of the Head due to repeated thermal expansion and contaction.
(2) check the signal cable for loose connection, twisting etc on both ends - at the back of the CPU and Monitor (it is fixed)
