Hi, I read that you can test whether or not a capacitor is working by using an ohm-meter. if its working the resistance will slowly increase if you connect the probe in the correct polarity and decreases if you connect it in reverse. Is this true?

I tried doing this on a power supply board, almost all of the capacitor behaved as described above, except two capacitor, does this mean these two capacitor are not working anymore?( I did not desolder the capacitors and just test them on the unplugged board)

I also did this test on a good capacitor and a slightly bulging...

Hi Folks, Ive gotten a used LG 32LX1D it will not turned on, only the little red light is on (not blinking, just on, from what I read its suppose to turn green when the tv is on).

I took out the back cover and plugged it in and a high pitch noise is coming out of the PSU, the noise sounds like [URL="https://www.youtube.com/watch?v=Itw0LKtwGjY"]this video[/URL] but at about less than half the volume.

None of the capacitor in the PSU is bulged and i've tested the white fuse and it worked fine. I dont have an esr meter to test the capacitor to see if they are...
