Won't turn off and cylces through colors

Good Day, When there is no longer a signal to the monitor, it begins to cycle through the primary colors. Not a big issue, however the power switch does not work at this point and he only way to stop anything from being displayed is to unplug it. Otherwise the monitor works perfectly. Even the power switch. This began after there was a power surge. The surge protector worked as advertised: nothing (monitor, speakers, computer) was fried. I have dual monitors with an ATI Radeon 9600 All In Wonder. The Acer is the secondary monitor. Any help would be appreciated.

Re: Won't turn off and cylces through colors

Hi. This evening, I had the exactly the same symptom. I found a way to fix it.

When you power up the screen, keep the power and auto buttons both pressed. That seems to reset the screen. After that when you open the menu, a small F appears on the left side of the contrast icon. Go to that red F with the arrows and press menu. Another menu will popup. Choose 'Burnin' and set it to off. That's all !

Note: do not try to change other settings, they depends of the harware...

Screen keeps flashing green-blue-red

The manual for the monitor can be found here (
Mitsubishi DiamondPoint V50LCD User Manual ) The specific Red Green Blue cycle isn't noted.
  1. I'd start with toggling on the on screen set-up display. if that comes up and is legible, then you know that the screen is working.
  2. What is your video set up to push to the V50? If it's not a supported resolution, the display may respond this way. try downgrading it something like VGA (640x480) and see if that works. (The max resolution shown in the manual is 1024 x 768, so don't go higher than that. It's also 24 bit color (8 bits each for R,G,B, so don't try to push 32 bit color to it)>
  3. Set the output to your primary monitor to 1024 x 768, thousands of colors. Make sure the monitor sees it OK. Now you know the first monitor and cable are OK. Now switch the cable to the V50 monitor. Do you get a signal now? Then the display works. Try putting your primary display on the second cable. Does it pick up anything now? No. Maybe a bad cable.
  4. You can try swapping the cable going to the V50 to go from your primary monitor output port on the computer to your primary monitor. if the primary monitor works OK, then the cable is good.
  5. Depending on the computer system you're on, make sure that you at least have a generic monitor driver installed for the V50 output. Ideally, get the driver for the monitor You can get the driver here (
Mitsubishi Monitor drivers ) amongst other places.

Good luck!

IBM L190 LCD - the LED beside the power button corner cycles green for 1 second, off for 1 second as soon as it is plugged in. The unit won't power up, the LED just cycles green/off whenever it is plugged...

It's clear the problem is the display, but you can still try these 1. unplug and replug while the both is on 2. turn on, off couple of times 3. keep the LCD on for about one hour these are anyway temporary fixes :(

Can't red and green colors

This usually means the red or green or both primary color module is bad. Monitors come with 3 primary color module controllers and they use them in various combinations to make the other colors. The primary colors are blue, green, and red.

My omnitech monitor is turning red when it wants to. no certain program just whenever

Colours on the screen are generated by "mixing" the 3 primary colours.
Of the primary colours is RED.
So, your LCD monitor is not receiving signals from your computer,
specifying the other two primary colours.

Check the data-cable between your computer and your monitor,
to ensure that the connections are tight at both ends.

Try a different data-cable.

Try your monitor on a different computer, with two different data-cables.

Try a different monitor on your computer.

It could be the video-card inside your computer is failing to "send" one or two of the primary colours.

Screen got yellowish color

Sounds like overstressed video cable, at least that wire for BLUE signal, 'cause when image is yellow - the BLUE color is missing.
Open the monitor and ring coaxial wire in blue insulation.

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.

Different color test patterns keep cycling .

This could be a computer or monitor problem. The reason that display shows up is because the monitor is not getting a power good signal from the computer. If a monitor doesn't get a power good signal it goes into test mode. It could be the monitor has a fault that is not allowing it to detect the computer, or the video card or computer itself isn't functioning properly. If you can, hook the monitor to a computer that you know is working properly. This will tell for sure if it is the monitor or not, and eliminate that possiblity. Then you will know if it is the monitor or computer. If the computer is the problem you'll need more help troubleshooting it.
