So I have a Sceptre X20WG-Naga LCD monitor, and it won't turn on. The power light on the front works, but nothing else does. I suspected the inverter and decided to test it. Sure enough, it wasn't outputting on the 12v rail and I noticed two of the smaller caps on the board were leaking yellowish fluid.
I replaced all of the 470uF @ 25v caps on the board with new ones from other monitors (which had various problems like shattered LCDs). After that, the Sceptre power supply still didn't work. Just to make sure, I tested the large capacitor on the board (68uF @ 450v) and it seemed to be working fine. I soldered the big cap back into place and retested the inverter, and about twenty seconds in, I heard a loud pop and saw a bright flash coming from the same cap. I guess I left two solder points touching accidentally or something.
I checked everything to make sure nothing was touching, and now the power supply doesn't output on its 5v rail either. Where before I could hear the large capacitor charging and discharging much like the cap in a disposable camera, now the inverter is completely silent.
I've looked for replacement inverters online, but can't find any. If anyone has a particular parts store that they like, I'd really like to try looking there.
I'm assuming I'm out of luck, but is there anything I can do?
Sorry for my noobishness; this is my first time trying to fix a monitor.
