You have problem with the psu.Three capacitors 820mF/25V are dead and there is a fuse 3A worn out

I will go with Cropp on this one however if you cant find it at that site you may also try driver guide.com

go to technician, your monitor have a depective capacitor, screen need a couple hundred of volts, so if one capacitor s depective your monitor is shuting off.

This monitor contains a latches to open. Its recommended that you use suitable tools and service manual.

If the unit is in warranty its recommended that unit to be serviced by service Engineer.

You still have shorted out components on the circuit board, you will need to download tha service manul here to do an indepth troubleshooting: http://elektrotanya.com/

That sounds like a capacitor or maybe a mosfet died. Usually only capacitors 'sing'.

first you need to confirm it is the backlight section that died. simple visual inspection. You want the monitor plugged into a running booted computer. If you have anything that will do dual screen that lets you know what and where something should be on the screen being tested.If not anything will work. Let the computer boot up and then you will need to get close and near an edge. What you are looking for is a ghost image of the normal desktop. You may even be able to see the mouse move around. This is the actual picture produced by the lcd. It is very faint. The backlight acts somehwat like a projector bulb and shines through the lcd panel. So if you can see anything then your backlight or the backlight power are the problem. I'm in BC so its hard to reccomend any place for parts. Most of the ones I have fixed the parts were out of California.Cost should be about $70-$100.

If the backlight isn't the problem then it is usually a power section problem. The parts are cheap but the time to find the bad one can cost a bit. If you can find a place to fix it get an estimate. Then check out the replacement price of a new monitor. The prices have dropped and sometimes it isn;t cost effective to repair even a backlight on some models.

It is probably OK, possibly a filtering capacitor, besides no one makes a 820uF any more.

There is a inverter transformer on the board that may be defective that generates the high voltage that drives the lamp, you may end up having to replace the whole inverter board to get it working again.
