How to Troubleshoot & Replace Lg AP5201790 / EAV43060807 Led Assembly (Backlight)

Installed new led board 

I found the part easily on appliancepartspros.com, ordered it and received it in just a few days. It was a circuit board with led lights that installed in just a few minutes. The whole process was very simple and easy. 

The representative was very helpful in finding a solution when some parts were discontinued. Great service and the parts were received quickly. 

Water filter and led light were simple repairs. The water line was more difficult but turned out to be easy after I watched the video from Appliance Part Pros. Thanks for that one!! 

Upon identifying the correct replacement part, I ordered it from APP and, exceeding my expectation, the order was acknowledged and shipped the same day I placed it and, to top it all, the part was delivered by Fed Ex the nest day. I installed it in less than 15 minutes. A perfect performance by all, including myself, of course. I hope that the new installed part will last longer that the 8 years of the original one. Thank you!
