Re: backlit problem with ViewSonic VE150m (Beige)
I had a problem with one of my viewsonics, and called their tech support, they gave me an RMA number once I explained a similar problem to them and fixed it for free. It sounds like it needs a power board, but if you call Viewsonic they will fix it for you for free. They may ask for you to pay the shipping one way, unless it's under a year old or more with extended warantee, they will take care of you, don't mess with it yourself, unless you are a tech yourself, once you start taking it apart that is the end of your service warantee with them, thanks

I suggest you connect the VGA cable from the computer to another monitor or a laptop, just to make sure that your monitor's back light is faulty. If it does show on the other monitor or laptop, then the back light is really faulty. And i suggest that you get a computer technician to open it up for you if you can not do it yourself. Or you can get a sharp-flat object and open the monitor starting from the bottom of the monitor working your way round to the top. You will notice finger-like structures that hold down the monitor covers together. Make sure you do not break any of those. When you open it, check on the circuit board where you connect the power cable. Check for any bulged or leaking capacitors. Capacitors have a job to hold down the power from the source long enough for your display. For faulty capacitors, the monitor will either remain black with the orange light blinking, or it will display for at least between 2 to 8 seconds and then goes black. Buy the same type of capacitors and replace the damaged ones. Please not the polarity as you replace the capacitors.. Good luck
Please try to connect other monitor to your CPU.because I know the problem is in your video card graphic.also change your screen resolution to 1024 by 768.
if same problem again. need to check-up your viewsonic p75f+ crt monitor. some parts of your vertical video section capacitor leakages.
I can't tell you what it means but it happened to my laptop this morning. After reading tons of "solutions" nothing worked. Finally, I turned it off, went grocery shopping for a couple of hours and when I came home and turned it back on and it seems to be fine. I am, however, going to make a recovery disk like the computer has been suggesting since I got it.
the monitor may be going into power save mode which it should come out of when you press a key or move the mouse but it sounds like you have tube inverter issues.
Your screen has light tubes behind it to illuminate the screen, if the tubes or the inverter develop a fault, then a very dark screen can result as the tubes are turned off.
There may also be an ambient light sensor which will darken the screen in low ambient light. If the sensor is faulty, darkened screens will result. If the inverter is failing, you may be able to replace it, contact viewsonic. if the tubes are failing, replace the panel or the entire monitor. If the ambient light sensor is faulty, replace the panel or entire monitor as the sensor is part of the display panel.
Are you still using the same computer that was set to 200Hz? If so,
start Windoze in safe mode and reset the display properties to 1024 x
768 60Hz. Reboot the computer and everything should be OK.
Does this model use an external ac adapter or an internal power supply?
Twice I have seen a white screen caused by bad capacitors in the power
supply. They may look good, but you should replace them anyway. Look in
the 2ndary circuit of the power supply, you should see some capacitors
that are (for example) 220uF 16 to 25V, 470uF 16 to 25V, 1000 uF 16 to
25V (all those capacitors could be 16V or 25V). Replace them and try
the monitor again.
If it uses an ac adapter, try a different 12V adapter. Make sure it has
the same or higher amperage rating. If you can't find one, you will
have to measure the power going onto the board inside the unit while
the adapter is plugged in and the monitor turned on. If it is less than
12V you need a new adapter.
If none of this helps, the panel or main board may be damaged. In most cases these two parts cannot be repaired.
