I have repaired 6 or 7 of LG's 65UH5500 all with LED failure. In each case, I've found one strip that has failed. When I replace the failed strip with one from a brand new/cracked screen unit, the TV works for a while and then eventually comes back after a month or two with a DIFFERENT failed strip (in a different spot in the grid). Never the one I replaced, always in a different spot.
Anybody have experience with this problem with this model? I have more of these TV's to repair but there is no point in replacing strips if the TV keeps coming back because the "next" weakest strip has failed. Is it possible that the LED controller is over driving the LEDS (beyond the usual LG LED failures) and burning them out prematurely? (I have had the same experience with the 55UH5500 version of this TV and so have stopped repair those until I come up with a permanent fix).
Any thoughts on what I'm missing?
