Vx900 viewsonic monitor problem . Blank screen except for power off/on

My 3 yr old lcd vx900 monitor suddenly went blank except when I cycle power. The image then appears just fine for one second and then goes blank again. View sonic said it was the inverter (power). And would cost $120. Does this sound right?

    exactly the same problem that I have. The screen only flashes on for a split sec and then goes black.

    Yes I have the same model with the exact same problem.

    Same problem. When I turn the monitor on, the image flashes for a fraction of a second then the screen goes black (but the green light stays on which indicates the computer is still sending it the signal). Same whether I use DB15 or DVI.

Search for "VX900 inverter" on eBay. A company from China sells for $21, new, free shipping.

    Yes. The inverter WAS the problem. LCDPart.Com sells it for $80 and has a PDF document that guides you to change it. If you are on a budget, an outfit from China sells them on eBay for $21, shipping, included. The only problem is that their part is wider and shorter. So, although it works, you have to tape it down in place because it does not fit where the original comes.

Check to see if you do have 12vdc output from the power supply module, then also check the fuses on the backlight inverter board.

When booting up my system in the morning the monitor is blank for about 15 minutes then it pops on. During the 15 minute warm-up there is a very dim pulsating of the screen every 3 or 4 seconds.

The power light is red and blinking rapidly, screen blank

is it plugged into wall or a surge? may make a difference. Some screens require certain amount of KV and some surge protectors have less KV than needed to run some things. good luck

I am using this great LCD for about an year. But few times in the past my LCD didnt show up the display though the Green light was still ON, turning off the LCD and opening it again always solved the problem.

Viewsonic VX900 blank screen

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.
