Question about ViewSonic VX922 19" Monitor Flat Panel
I have exactly the same problem with the two VX922 monitors I bought around September 2006. They both started doing this at the same time just a few months ago and the problem is becoming worse. It now takes anywhere from 10 to 20 minutes now to get these **** monitors working in the morning, and now they even go out sometimes while I'm working during the day. NO information about this at all on the Viewsonic website and NO replies from Viewsonic after I contacted them. Since I've seen this problem posted by hundreds of other people on other websites, I think we could be looking at a class action lawsuit against Viewsonic. I certainly won't be buying another Viewsonic monitor, that's for sure!
If there is a flashing led on front of the monitor, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.
1 The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.
If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours, sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occurr suddenly are a blown capacitor on power board, the inverter board powering up backlight lamp has blown, or a fault on main lcd controller board.
check also the video cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
Check connectors, try moving the video cable, and if the cable is not built in, then also try a replacement cable.
If under warranty contact Viewsonic to find out a Viewsonic service point.
