Hey...Dude,
It's seems you guys need to replaced a couple of capacitors on the backlight inverter....not fuses. The caps look like a tiny battery, on top there were a + or Y mark on it.

The green power light comes on but the screen is black? What do i do?


More likely the backlight inverter board is bad, you need to check and see if the surface mounted fuse/fuses are good on the inverter board, also check to see if it has 12v feeding it, post a pictures for further help.

Check the fuse on the inverter board and also verify it does have have 12vdc feeding the fuse. Worst case will be the lamps, power supply caps look OK?

There are two places to look for the problems, the backlight inverter board and the power supply, look for burnt parts, bad capacitors, etc.

ViewSonic VA912b monitor fading out during boot


It is probably the power supply, or the inverters.

Similar problem with solution, though it requires you to know something about electronics.

Here is a pic of the fuses on the inverter board for a Viewsonic vx900, you can visually inspect them as well if you do not have a volt meter. While visual inspection is not 100% reliable, usually when these are popped you will see the red line across them is black or broken.

I have repaired 3 Viewsonic VP211b monitors.
The power light comes on but there is in picture. In all three cases it was the same problem. It was a blown fuse on the inverter board.
1. The monitor must be opened: The black plastic back is pried off carefully. It is easy to damage or crack. This will expose the electronics.
2. Remove the metal covers: The power main board has a metal cover that is secured with 4 screws. When that cover is removed, you can then remove the cover over the inverter.
3. Remove the inverter: The inverter is held with 1 screw. There are a total of 6 pairs of wires to the fluorescent lights (3 on each side) that must be disconnected from the inverter and a there is a power and control cable to the main board that must be disconnected. The inverter should now be free.
4. Test the fuses: On the inverter there are two tiny surfaced mounted fuses, labeled F1 and F2. They are on either side of the power cable CN1. Either one can be blown. Test them both with an Ohmmeter.
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.
I replaced them with the same fuse, except Fast Blow rather than Very Fast Blow. The replacement fuse has just the letter N. The FN was not available at the time and I felt the N would be close enough. The fuses were made by LittleFuse. They were purchased from Newark Electronics. Part number 64R8010.
Prior to acquiring the surface mount caps, I tested the inverter board by soldering a regular fuse across the blown fuse and putting the inverter back into the monitor. The monitor came back to life. Normally when there is a fuse blows, it is because there is a short someplace down stream. How ever the new fuses have held. Therefor I am assuming it was just faulty fuses.
With the new surface mounted fuses, the repaired boards were placed into monitors and they all worked.9486ec61-dd3d-4a22-bbc3-82b55a458b09.jpg00ad0ac3-9cf1-4fff-83ed-90d93e6a0e0a.jpg40cff7a9-f7c7-4904-aac3-eb656a117911.jpg0ee0c7e1-1e8a-4b07-936c-83557d5ddd2b.jpg3ccdb800-f497-41ee-b268-cad6a2330191.jpg4d8ec0f3-f0e3-4e06-bc47-791b2996f04b.jpg

19"ViewSonic LCD Monitor wont work at all !!


If you have the pc on and the monitor light stays green, take a flashlight to the screen. If you can see the images while shining the flashlight into the screen, they will be hard to see but they will be viewable, then its most likely the back light. The vx900 takes 4 bulbs and they are about $12 US each. Anyone who knows how to solder should be able to replace them.
