When after power up the computer press num lock key if num lock led is flash on and off when you press num lock key then your cpu is working fine.But if it stay constant then open cpu cabinet cover then reconnect RAM memory and processor and it's fan pull cmos cell from motherboard for 10 minutes then reconnect it then check.Make sure motherboard is not ground with cabinet. If num lock led is on and off then when you power up the computer press F8 key 5 to 6 times so you can see safe mode and other menu then enter in "Enable vga mode" then go to display property ->settings change screen resolution to 1024*768 then apply and ok. then check. If everything are fine in cpu then your monitor need repairing. Let me know if you need further assistance. Thanks for using FixYa.

Monitor goes dark 2-3 sec after power up, green lite stays on


Look for shorted out transistors (four, c5706/5707) in the inverter backlight transformer driving circuits.

The problem can be the lamps are bad, the only way to tell is to remove the lamps, look for poor soldering works where the wires are attached to the lamps, bad lamps will have very dark color at the end of the lamps, just like bad fluorescent lamp you see when it is worn out, anoher sign of bad lamp is pinkish glow when lamp si first turn on. The transistors and caps are good in the inverter section?

Hello,

The power supply in the unit has died. This is a very common problem with this series of monitor after 2-3 years of use. If you can solder then you should be able to do the repair yourself. Check out our step by step repair guide posted on our site at: www.ccl-la.com Our guide gives parts values and location information as well as how to open the unit up. If you don't feel like doing the repair we also offer repair services, see our web site for details.

When you switch the monitors, do you still use the very same vga cable? If you don't, then it's time to change the monitor. When it turns on and off inmediately it means that it's receiving the signal, but that's it. If it's brand new, exchange it.

Viewsonic VE175b Monitor Powers Up Doesn't Display Windows OS


Hi; I had the same problem. I know that sometimes devices require you to perform some type of '10-30 second' "hold" of one or some of its buttons in order to 'reset' the device, so to speak. So, having said that, try this:

1) Turn your monitor off (no green light) but leave it plugged in.
2) Leave it off for about 10 seconds.
3) Hold the [2] button on your monitor (the one to the immediate LEFT of your monitor's POWER button).
4) While holding the [2] button, now press and HOLD your POWER button.
5) Wait for your image to appear and STAY onscreen for about 5 seconds, then release both buttons.
6) Your monitor should retain its onscreen image.

Hope this helps! Good Day to all!

Screen displays fine for a second, then goes blank


Dor, BenQ has a 3yr warranty on their monitors. I would contact their tech support and receive an RMA to return it for repair. It will cost you shipping out there but they will ship it back. I has a BenQ FP731 myself and it blew a capacitor inside that allowed the screen to stay on. Fixed it and had it back in 5-7 days. Good luck.
