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.
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...

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.
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)>
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.
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.
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 (
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.
It might be the input from the graphics card. Try swapping the two monitors' feeds to see if the problem is with the monitor or the card. The monitor seems to be going into a screensaver mode since there's no signal. The flashing light could mean there's a power supply problem, or no signal.
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.
I suspect the power supply for the monitor. Try a power supply from a working monitor. If you have a used computer store nearby, take your power supply to them and try it on another monitor.
There is no need to turn off a monitor using its power switch. Monitors automatically go into standby mode when they are not receiving a signal. In standby mode they use less than one cent of electricity per day. If saving electricity is your goal, raise the temperature in your home by a degree and run the air conditioning less.
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.
