Re: lg 42ln5700 no power, no standby light
Fried the board with my Weller 40 watt iron at max setting attempting to desolder a fuse. Got most of the components out. It was an awesome newbie experience. I'm wondering if I should purchase the Ps board and progress my diagnosis or start on another r&d project.Last edited by StinkyOnion; 12-28-2015, 09:31 AM.

lg 42ln5700 no power, no standby light
PO claims tv was hit by lightning. Checked standby voltages on the two pins on the ps board going to main board and measured 7v on both. Also checked transformer el47 and got no reading and a .3 reading on a capacitor labeled c508. This all before I believe I blew the fuse closest to cord plug in. Now the fuse is reading 120v one side and .3 the other and so is pretty much every other ic is the approx. reading.
This is my first attempt at tv repair so any constructive criticism is greatly appreciated.ty
