Okay… in a nutshell; tv stopped working as described in the subject line. No sound, no picture, no back lights (LED’s), no stand by light, no nothing. Did continuity checks on fuses and checked a few voltages. Thought I had it narrowed down to the power board so I purchased a known good used replacement power board. Swapped boards and; nothing changed. Decided next would be the main board so I purchased a kit from SJ.com which includes a new main, power, t-con and wifi boards. When those arrived, I went from replacing one board to the next until I replaced all of the boards (except for the wifi board which I did not think would matter in this case) and still nothing changed!
There are not too many more things to replace. What can it be? LED driver boards? Can bad LED bulbs or strips cause the tv not to come on with no sound or picture or standby light? I’m at my wits end, almost.
Would replacing the LED strips be the next logical thing to replace?
Thanks!
