I think you have bad CCFLs, (Cold cathode fluorescent lamps) they look like small flourescent lights and are used to light the screen. On smaller than 17" screens there are two, one on top and one on the bottom. 17" and larger monitors have 4 with real big ones having 6. If you attempt to change them be very careful not to crack the screen and remember the order of all the layers of the screen. The cost of the CCFLs along with the difficulty in doing this repair makes it not worth most peoples trouble....good luck

The fuses are on either side of the connector. They are semi transparent SMD chips. It's easy to see if they are flow or not, just look at them with a magnifier.

The problem with my monitor is everything works, I get a picture. But after turning the monitor on, the backlight almost immediately goes out, but you can still see the picture just barely.

Any advice on where the problem is? I'm guessing on the inverter board. No obviously blow parts. Capacitors maybe? There are to large electrolytic cap on the inverter one for each side.

Has anyone actually repaired one of these successfully? And what was the failed component?

No power on my lt26hve flatscreen olevia tv


No power can mean many things, but since you've asked another question about the main fuse value I'll also use this chance to remind you that when a fuse blows it is usually to protect other components because of a failure in the board.

In other words, replacing a fuse with a good one alone hardly ever makes things work.

Most of the time - especially if it is the main fuse - it will just blow again.

And the resolution is to have the board repaired or replaced.

I can see power boards are hard to find and cost north of $80 , which is a lot for 26'' TV repair.

While we haven't serviced that board before , we'd be open to taking a look and seeing if we can make it work..and if we do it will be for the reasonable price of $65 including return shipping. (note for future readers: price may change at any time, so make sure to check with us first!)

At the very least, you don;t have much to lose by sending it - we will pay you the shipping costs if we can't fix it and you decide to abandon it with us.

If interested use www.coppelltvrepair.com/newservice to start the process.

If not...get a new board and hold your fingers crossed!

Hope this helps!

One of the tiny fuses in my Viewsonic VX900 monitor has blown. What is its part number, and where can I purchase a replacement? In addition, if I have to replace the entire inverter board, what is its...


I replace the surface mounted fuse with axial-lead fuse, PICO fuse made by LITTLEFUSE. You can try using a 1 Ohms 1/2 watt flame proof resistor in place of the fuse, if the resistor get real hot and burnt up then it may have shorted Transistors or transformer. You can get the number of the board and go to www.lcdparts.net to see if he has the inverter board in stock.

You may have backlight inverter failure, check the fuse as shown in my pictures, you can also have bad backlight assemblies also, but check the fuse on the inverter bd first, verify that you do have 12v at the fuse.

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.

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.
