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 this video 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 really good. this is the service manual of the tv. anyone has got any suggestion? PIctures of PSU
I dont have much background in electronics, but im good with a soldering iron, i've replaced quite a few bad caps in other tvs, even soldered quite a bit of smd led on some other project.
thanks
