Ok sounds to me like a power supply problem.. this a a fairly common symptom. I suggest that as a temporary fix you set the monitor to NOT turn the power off to the monitor in sleep mode if possible, in your power settings for the monitor.

SOURCE: ViewSonic Monitor has trouble to wake up after been shut down.?

i have the same problem, my viewsonic lcd is also 2 years old, hmmm...then maybe "the" 2 years do something to them since everyone else exp the same prob after 2 yrs.

but, i find a "not so smart" solution, my lcd will turn back on whenever i unplug the power cable and then plug it back in, (won't turn on if u only press the power button)

so what i did was bought an electric switch (on-off) in the edge of my lcd's power cable, so whenever it goes blank, i can easily and quickly cut the electricity without having to bother unplugging and plug back the power cable.

hope it works for u guys

My screen is saying burn in and keep switching colours all the time.(white,red,green,blue.


You may need to send in unit for service because your unit is unable to go to sleep mode when the signal cable is disconnected or the PC is turned off. Please call ViewSonic Customer Care for support.

Although this will not hurt the monitor, you just need to apply an active video signal to get a display correctly. However, it will not work as expected to go into sleep mode. You'll need to call ViewSonic Customer Care to get this taken care of.

My ViewsonicVP930b Monitor Suddenly Turns Off


This is a classic VP930 problem.

It is caused by bad capacitors in the power supply circuit.

Open the monitor, and look at the power board. There are six capacitors. Replace the 220uF @ 25V and the 1000uF @ 16V capacitors. I would recommend replacing them with 35V and 25V capacitors respectively.

If the serial number on your monitor starts with Q8H you could also have a bad IC on the main board. Q8 on the main board is an FET in an IC package. If this problem persists solder a wire from the right side to the left side. There is one pin that turns the IC on and off. All the other pins (per side) are soldered together. Do not solder the pin on the left side that is by itself. Just leave it. Solder ALL the other pins on the left to ALL the other pins on the right.

Remember, do this ONLY if the problem persists after replacing the capacitors AND if your serial number starts with Q8H.

Sharp light turns green thern turns yellow screen goes black


it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.

although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode

some one else suggested that i remove and reseat the video card

hopefully one of those will work for you

Viewsonic E53 monitor


Base on the information given to me.

I think your computer is on sleeping mode.

first thing check if the video cable is not loose connecting the pc.

because what would happend, if it is loos it would turn on and off at times.

The other thing you can do.

right click on the desktop.
go to properties
go to screen saver
click on power

adjust the time you want your monitor to shut off.

Problem solved! The main power thingy (the thing with the big red wire coming out of it) was all black and dusty. There was 'soot' all over the whole insides of the monitor. I concluded that this monitor should be laid to rest, and a new flat-screen monitor erected in its place.
