If you can always hear your laptop fan when you turn on the laptop and now you can not listen it's not the vga problem, the problem of power or mainboard.
The next troubleshooting step is to connect an external monitor with a standard VGA connector, whether CRT or LCD. If your notebook still does not turn into an external monitor, it's quite possible that one of the motherboard components or internal video adapter (if it is not part of the mainboard) has been damaged. Possible damage to motherboard components on the above analysis is Vga pa... paprocesor... ic chips Mboard epromer........ power ic power module component: if the lead did not fire at all.
If external monitor works well, some problems occurred in the video subsystem of laptops, which usually contained entirely on the screen / lid assembly (flif). Or one bundle cable / lcd cable (video signal or power) that run through the hinges to the video subsystem has failed, except for problems clearly in the Tubes Lcd, (cracked screen, fading in the corner, a faint image, bad pixels). For your LCD replacement still have to open the main part of the laptop to check the connection. The easiest problem to identify perasalahan clearly is (physical damage) LCD cracked, Changing the LCD is almost the same on most notebooks.
If the brightness of your screen seems to turn on or sometimes bright and sometimes almost fade away (imagine) or completely dark, (do not be fooled by the power saver mode), then you might have a backlight or inverter problem.. Between the two, the inverter several times more likely to be problematic, serves as a ballast of solid in the modern fluorescent lamp. The backlight itself is a CCFL (Cold Cathode Fluorescent Lamp) with a time that will be a very long time for the damaged / broken, while an entire generation of inverter together on some laptop models, you can easily find a replacement spare parts, whether original or compatible. (Replacement method inverter discussed in other sessions).
