Re: Sceptre X20WG-Naga inverter problems

Alright, so I manually added some electricity to the twelve volt rail and found out that didn't help. I've also discovered that when the monitor is off, the front LED should be red, and when it's on the LED should be blue. Currently, both the red and blue LEDs are lit, which makes me think it might be a controller issue.

I've also noticed that when I plug the monitor into my computer, my computer can detect the monitor and its supported resolutions, and can try to use the monitor. If I shine a bright light over the monitor,...

Re: Sceptre X20WG-Naga inverter problems



So should I check to see if the transformer is somehow not working?



I'll see if I can get my dad to bring home his work camera tomorrow.



Yeah, I know, but I don't have a fuse to replace it. I'm not sure it's [i]quite[/i] as dangerous as lighting a match to find a gas leak, though. xD

Thanks for your help.Re: Sceptre X20WG-Naga inverter problems

Re: Sceptre X20WG-Naga inverter problems

Woot! I got the 5v rail again. I realized that I blew the fuse when the capacitor discharged (apparently it accidentally touched a pair of pliers I had laying nearby), so I've bypassed the fuse and I'm... right where I started. Could it be something other than the capacitors?

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...
