Question about ViewSonic VX922 19" Monitor Flat Panel

1 Answer

VX900 power issue

The monitor is actually a VX900. When the monitor is attached to the computer ond the computer is powered on, the power switch does not work. It will not work until it's unplugged from the AC and then repowered. The power switch will then turn it back on. THE INTERESTING PART: If I turn the computer off or disconnect signal cable from monitor, the power switch works perfectly. Moniter turns on and off with no problem.

Re: VX900 power issue

Strange isn't it. I'm thinking it's in the monitor powersupply relay capacitor holding a charge and not discharging. Then again it could be a bad pin on the monitors male connector. Or loose pin-connector in the video connector. Has it been doing this for a while?

My ViewSonic VX900 won't turn on. I have had it since late 2003 and it has operated flawlessly. Went to turn it on; nothing. No light, no standby light. Checked the power cord against another monitor and...


The VX900 has 2 different version of the unit. One version has an external power supply and the other has internal power supply. Since you said you changed the power cord I would guess you have the internal power supply version. The issue you have is caused by the capacitors on the power supply board have overheated and blown out. This is a common problem on many LCD monitors after a few years of use. If you open the back of your monitor and look at the supply board you should see the bulging capacitors. Check our web page at: for Pictures and examples of what to look for and what you need to get to do the repair. If you have any questions let us know on our web site and we will be glad to help you get going again.

I hope this helps, If so please rate our solution.

Even though you show 12 volts, you could still be coming up short in amps on your powerboard.
Updating the capacitors (all of them except for possibly the main) may correct this.
If that doesn't do it, then the inverter is the next target to check.
