Re: LG 47LS4500-UD No Power

Hey guys, so after finally tracking down the only electronics store in my small city I went to pick up some 1k resistors. Long story short, the old curmudgeon store employee would not sell me any resistors as it would be a waste of my money. He insisted my problem was bad capacitors on the power supply. He advised me to change all the capacitors and could almost guarantee this would resolve the problem. I'm not convinced,
based on what I've read regarding these tvs.

Im now looking to order some resistors or perhaps capacitors off...

Re: LG 47LS4500-UD No Power

thanks very much for the help. I'll hopefully have some time this weekend to work on it and reports back. much appreciated.

Re: LG 47LS4500-UD No Power

All the pins show 0 volts except the 3.5v pins.

Here we go. let me know if any additional pictures will help out. thanks!...

Hey folks,

I have an LG tv (47LS4500-UD) that wont turn on. There is no picture, sound or stand by light when plugged in. From reading other posts with similar problems, it sounds like the culprit may be a dead Main Board. I'm new to electronics but after reading these posts I decided to take the back off and due some voltage checks. I'm getting good stand by voltage on the power supply, but hitting the power button on the tv doesn't change anything across the pins on P201. I also read that on this model of tv there is a certain capacitor (C603)and diode (D607) that often fail....

Hey guys, I'm a electronics newbie. I'm a high power lineman so have some knowledge of electricity etc. Hoping to get into electronic repairs as a bit of a hobby.
