I picked up a 2013 Samsung plasma model number pn60f5500 for free today. Owner said the standby light would flash. I had a feeling that it was all due to a bad ceramic cap(10uf 50v) on the ysus board. I was right again! It works perfectly. I have repaired other models that have 3 of them in parallel before, but this one only had one with holes unused for a second one.
