Having problems with your ViewSonic VP930b 19" LCD Monitor ?

My ViewsonicVP930b Monitor Suddenly Turns Off

\015 Okay so my computer turns on fine and starts up good. But after 20-40 minutes my monitor suddenly goes black, and the green light on the monitor turns yellow. Afterwards you can turn it on and off and when you turn it back on its still yellow. Rebooting the computer makes everything work right again, but after 20-40 minutes the monitor turns black and the light turns yellow again.\015

Answers :

This is a classic VP930 problem.
\015\012\015\012It is caused by bad capacitors in the power supply circuit.
\015\012\015\012Open the monitor, and look at the power board. There are six\015\012capacitors. Replace the 220uF @ 25V and the 1000uF @ 16V capacitors. I\015\012would recommend replacing them with 35V and 25V capacitors respectively.
\015\012\015\012If the serial number on your monitor starts with Q8H you could also\015\012have a bad IC on the main board. Q8 on the main board is an FET in an\015\012IC package. If this problem persists solder a wire from the right side\015\012to the left side. There is one pin that turns the IC on and off. All\015\012the other pins (per side) are soldered together. Do not solder the pin\015\012on the left side that is by itself. Just leave it. Solder ALL the other\015\012pins on the left to ALL the other pins on the right.
\015\012\015\012Remember, do this ONLY if the problem persists after replacing the capacitors AND if your serial number starts with Q8H.
Either you have a "sleep mode timer on the monitor".....or you just need to adjust your power options in windows.
\015\012*Start > Control Panel > Power Options.
\015\012That should fix your problem.
\015\012Check ALL settings in the Power Options
\015\012enable wake up by keyboard (press enter or spacebar, usually) from standby/sleep modes, or just enable a screensaver and disable all hibernation, sleep, and standby modes.
