Viewsonic VX2640W was running with the screensaver on,then suddenly went solid white. Turned off for thirty minutes then back on with same result. Unplugged from computer and turned on. Still turn


1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

If you see a message box that says "Power Saving Mode" after pressing the power button, then it simply means that the monitor/display is not detecting the computer. Check the connection/cable between the display and the computer and make sure your computer is not in standby mode by moving your mouse.
From what you stated in your problem, you dont need a inverter or a bulb. If you have any image like the message box displayed then its working fine. It just isnt seeing any signal changes on the input and therefore goes into power saving mde. Try another cable or hook it up to a different computer to check the cable.

When i switch on my pc the monitor display a blue power light for 5 seconds and then it turns to orange and nothing displays on screen.


Make sure you have connected the Video cable properly, Please disconnect the Video cable from the Computer and connect the monitor only to the power source. If you monitor shows anything like "Check video cable" or "No Signal" that means the monitor is working fine. You just need to connect it properly to the computer


For any further assistance feel free to get back with your comments .

Monitor won't stay turned on. You push the on button and it flicks on and then immediately off. Help!


The possible problem of your monitor is may be cold solder, bloated elec. capacitor or defective lcd panel. If you found that bloated capacitor replace it and resolder all pins of inverter area. Defective lcd panel could cause of display flicks then immediately off.

When I power up my monitor the display briefly flashes on - to the login screen - and then the display goes blank. If I use the power switch to turn the screen on and off the same thing happens - brief...


Open the monitor, look for blown capacitors and replace them. If problem persist, test the light bulbs and the inverter. If the inverter includes ceramic capacitor, replace it. If some of the bulbs does not do the flash - replace it. Check the transistors of the inverter. Replace if faulty.

Black screen, power button flicks


The monitor should come when the power button is pressed once - period. If not, and it continues to happen when connected to another PC, then the hardware is having trouble powering up the panel / ccds and it should be replaced/serviced according to the terms of the warranty. I suggest to bring it to an authorized service center for proper diagnosis & fix the problem. regards

Acer LCD Monitor only displays "acer" logo


You are correct, it could be a power surge that has caused it.

Try this..
Unplug the monitor from the wall.
Remove all the video connections at the monitor end.
Wait 10 minutes then plug the monitor back into the wall (do not connect the video leads)

Turn it on and see if it goes past the ACER logo now. If so, replace the video cables and try the computer.
If not, then one of these will apply and a tech will be required..
  1. The internal bios has been corrupted.
  2. The power supply inside the monitor may have issues preventing the video board from starting correctly. This could be as simple as a few failing capacitors.
Number 2 is the most likely cause with an Acer monitor though. Any local tech will be able to correct it fairly cheaply, but phone around for quotes..they can vary a lot.
