I finally gave up throwing good money after bad.
On the up-side, I did use my ESR meter again a few days ago. I ordered and soldered some new capacitors in an Arris 6141 Modem. That didn’t work either. This “replace the capacitors” thing hasn’t ever worked for me.
I can’t bear to throw the TV away, or give it to BestBuy. I guess I’ll have to at some point.
I’m still watching an older model I had, ironically an LG 42”.
I wish some brilliant person would figure it out and post it. I’d be willing to bet it’s the same bad component—probably just a simple soldering job.
I don’t trust the boards you buy either to be functional.
