Re: LG PSU Troubles

I have illustrated on the image where exactly I shorted the power rail, I have checked all resistors around the area and cannot find anything out of place. The board will still turn on for a second then click off, I'm not sure how to test that IC near it, I'm not sure if it could be damaged by something like that.
I'm really stumped on this one guys.
Cheers, Jason...

Re: LG PSU Troubles



Hey mate, thank you for your diagram. I have checked extensively around the area and cannot find anything shorted or open that shouldn't be, i shorted the 17v rail right on the pin with the ground pin next to it if this helps.

Re: LG PSU Troubles

Certainly, they were over the max file size so I just quickly converted them with Foxit. Sorry for the inconvenience.

Here are the JPG's...

Re: LG PSU Troubles

No worries mate, I should have been more forward thinking and posted some initially, my apologies. I was unable to locate a schematic, would have been handy.

Hey guys, I recently repaired an LG EAY60968701 PSU (it was only a cold solder joint on the transformer) everything was running fine but whilst testing the voltages I accidentally shorted the +17v rail to Ground pin next to it with the multi-meter probe.

There was a small spark and now the TV will not turn on, the relay just clicks. I have checked the the voltage and it displays the correct 17v for a split second right before the relay clicks off. Checked the caps, the P-channel Mosfet seems to be fine (not shorted) but I can't for the life of me find out what was damaged in the short....
