When I first heard they were going to replace the Cold Cathode Fluorescent Lamps used in LCD TVs with LEDs I thought it would be a great idea. Now that I'm seeing many LED TVs coming in here with burnt out LEDs I'm not so sure it was such a great idea. I'm guessing part of the early failure I'm seeing with LEDs is because they are driving them too hard. Because I was seeing more TVs made by LG than any other model coming in here with bad LEDs I did a voltage and current test to see if I could figure out why. What I discovered is that some of their smaller LCD LED TVs have an excessive amount of current and voltage going to their LEDs for the first 10 seconds that the TV comes on. In this video I talk about some of the problems I've seen, and I hope others may contribute additional information on this topic. After making this video I learned that Union Electronics sells LED replacement strips for LG TVs at a good price.
