Answers :

Just fixed mine :)

Biggest mistake was to try to open the monitor itself :( But I didn't brake anything :D

You just have to gently open the transformer unit (power brick) and replace two identical 1000uF 16V capacitors.
Here's how:
Remove the power cord first, to discharge the capacitors to avoid any nasty shocks when inside. Remove two rubber feet on the bottom side of the power brick. Just use your nail and lift them. Put them safely for later assembling. Unscrew two screws you just found under the removed feet. Now you have to unlock the other side held together by plastic locks. Try to apply pushing force and toque with screwdriver just where the seam is meeting the power cord socket's edge. Look for two identical capacitors and check if the tops are bulged of broken. I assume they are but you can try this method anyway. When the unit is disassembled you'll have to unsolder at least one of the wires that hold shielding plate on the bottom of the circuit board. Then unsolder the two capacitors (1000uF 16V). Replace them with the same type (1000uF) and the closest voltage possible. I have replaced mine with 1000uF 24V ones and so far I'm typing :D
That's it. If you have done this and looked for other damaged capacitors and replaced them also... Well then good luck disassembling the monitor unit and checking on inverter and lamps ;)

Cheers!
First place to look is in the power supply section, look for bulging tops, second will be the inverter board, third will be bad soldering works of the wires attached to the lamps itself (I have been running into a lot lately on the newer monitors, it is kind of sad how they build things these days).
