[QUOTE="Tony, post: 159996, member: 1"] So I have mentioned my 24" monitor with no backlight before in this thread. I finally received my mosfet (the part that caught on fire) so I soldered it in place and there are more issues than just that. I did find a bulged 220µf capacitor so I replaced it and still the same issue. There is a flash of the backlight then nothing. This monitor is LCD not LED (which LED is still LCD but with a different backlight lol) so it has CCFL (Cold Cathode Florescent Lamps) and it is possible the lamps are bad, but for all 4 of them to go out all at once is quite rare.
