determin if the speakers are at fault first. un-hook them and turn on the unit if it stays on one of the speakers is bad. if it remains in protect, the output transistors are shorted. there are a pair for each output. they are located on the large heatsink in the center of the unit.

Bulging or "blown" electrolytic capacitors are a common problem with LCD monitors. If you replaced them with correct parts (voltage rating) then one of two situations comes to mind:
1. Electrolytic caps are polarized, if you install them backwards they will blow quickly.
2. The voltage the circuit provides exceeds the rating of the cap. A 5 volt cap in a 12 volt circuit will blow quickly. The voltage regulation circuit may not be working.

I am guessing that the ceramic resistor is close to the output transistors. I would also guess that one or more of the output transistors has shorted. This causes a high current draw that is blowing the fuse. You could also have a power supply problem. The ceramic resistor is a .22ohm dual emitter resistor that is used in the output stage. The transistors located close by are probably shorted and should be replaced. Start there and let us know what happens once the transistors and the resistor are changed.

SOURCE: X2GEN CAPACITOR LOCATION
I had the same problem with my 22" X2Gen, first the monitor started what looked like a random color temperature shift, ie the screen would switch between a yellowish and blueish tint, then it wouldn't turn on and the amber standy by light flashed on and off. I took it apart and replaced the 2 220uF25V capicators with 2 220uF35V caps I got at radio shack, part number 272-1029. Don't worry about the voltage mismatch I'm pretty sure it doesn't matter, the voltage is the maximum the cap can withstand and has nothing to do with the voltage in the circuit. The caps are located on the board that the AC cord plugs directly into, it has a plastic (almost feels like paper) sheild, the caps are marked C812 and C813 on the circuit board. There was no 47uF35V cap that I could find, anyway replacing the two did the trick, all for under $3, I almost went out and bought a new monitor ;) Hope that helps.

if you have access to a multimeter, you should test you impedance (ohms)
Ω, check to make sure the speakers reads higher than the amplifier needs; this will result in less strain on your amp and diminishement of sound...For example: if you connect two 4Ω
speakers in series it results an 8Ω circuit (least strain). and if you'd take the same two speakers and connect them in parralelle it would result in a 2Ω circuit (most strain).
