I have repaired several of these Viewsonic VP211b monitors. In every case, the problem was a blown fuse on the inverter board. There are two fuses, F1 and F2. Either one can fail. The fuses are located on either side of the CN1 connector. These fuses are 1.5 mm long, 1.0 mm wide and 0.5 mm high (Case Style 1206). They have the letters FN printed on them. The N is for 2 Amps and the F is for Very Fast Blow.
The fuses were made by LittleFuse. The replacements were purchased from Newark Electronics. Part number 64R8010. This part number is the Fast blow 2.0 Amp (not the Very Fast blow), but they work fine.
Troubleshooting hint:
The screen is illuminated with fluorescent back lights. Those back lights are powered by the inverter. If everything is working except the back lights, you should be able to see a faint image by shining a bright flashlight into the screen.

SOURCE: ViewSonic VX910 monitor has a power supply issue.

Your monitor have a bad condensator in the PSU.

The only thing to do is to replace the Power Supply Unit (very expensive, more than a new monitor) or if you have electronic tools, found and replace that condensator.(cheaper way...)

or

Have you connected your monitor with a new power cord ?

Best Regards!

SOURCE: hi, my viewsonic va912b monitor disply 'no

Try this first. Unplug the monitor power. Let it set for a few seconds and then plug it back in. This corrects this problem most of the time. If that doesn't work, try doing the same thing with the video cable. Disconnect it from the PC and then reattach it. The connections may have gotten corroded and are not making a good contact.

Hope these help you. because beyond that you are looking at either replacing the monitor or the video card.

SOURCE: ViewSonic VE170b 17" LCD Monitor Faulty power

You need to check the fuses on the backlight inverter board, also the logic board may be damaged by the AC voltage.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

SOURCE: my monitor blureed

Both suggestions are good starting points, but it may be an internal fault.

Other steps to try: check the signal cable -- wiggle it a bit at the PC end and at the monitor end, while watching the image on the monitor. Any change? If you have issues when moving the cable at the PC end, you may want to try shutting down the PC and disconnecting the monitor. Then clean the pins on the monitor's connector with 91%+ isopropyl alcohol and a cotton swab (make sure no cotton is left behind). let dry and try again.

If none of this make any difference, wait for the monitor to go dim. Then, gently smack it on all sides. If the image clears up or changes, there is likely an internal bad connection. Do not open the monitor unless you are familiar with all safety precautions involved.

I have the same monitor and I was having a similar problem. Turned out, there was a cracked solder joint on the signal board at the back of the CRT plus several more questionable ones.

Monitor only works for short period of time


These monitors have a problem of poor quality capacitors. Loss of power as the monitor heats up suggests bad caps. Marginal caps perform worse at higher temps. I repaired a VP211b in 2006 by replacing C52 and C53 on the power supply board. These are 680 uF 25V. I replaced them with 1000 uF 25V because that is what I had on hand. The monitor worked good until now (2015).
Like yours, it would lose power as it heated up. This time the big capacitor on the power supply failed. It is 150 uF 400V. Replacing the bad cap fixed it. These electrolytic caps usually swell when they go bad. The top will curve upward. There may be some brown material leaking out. Any swollen cap should be replaced.

Gateway FPD1750 monitor's keep go black screen, no picture at al


tgordon60, If you know how those NEW "CURLIE-Q" energy efficient CFL light bulbs produce WHITE LIGHT, then you will know what makes an LCD display panel produce all the pretty colors and the WHITE BACKGROUND of the FIXYA web page!!! Only difference is that your "cold-cathode-fluorescent-lamps" are thinner and straight, and hung on rear of LCD glass panel and have a DC to AC electronic ballast called an "INVERTER" circuit to produce 600 to 1000vac to light them up. Get to my FIXYA profile and read my responses to other BLACK screen lcd owners to learn about all your options for repair. Follow any of the links to other web pages you find there. Your monitor not any different than ACER, DELL, VIEWSONIC, BENQ, SONY, AOC!!!!! 12fixlouie aka louie12fix

ViewSonic VX2235wm monitor looses power ...


I've not seen this problem on a ViewSonic but have on a Dell flat screen. The fix was the obvious one: the power connection on the back of the monitor was loose -- have you checked this. Also if the power cord is too tight it could be the problem. Other then this, it sounds like a short inside the monitor.

Hope this helps
