Default Re: Samsung PN64H5000 clicking when powered, then stuck in standby

Major thanks to Bobby Kolev (at Coppell TV, which I'm not affiliated with), and an unnamed tech at Quad City Electronics (again, no affiliation - I'm just giving props for the excellent help. The former sent me the video link in my last post, which allowed me to properly test the power board. The latter helped me properly test the Z (X?) sustain board to discover it was shorted.

Bought a new Z board on ebay & popped it in. TV is once again working - result! Who knows for how long, but for someone who got his EE degree 30 years ago and hasn't used it much since, putting those tuition dollars to work was pretty satisfying. And it only cost me $60.

Bonus: so far, no magenta flickering, as described in my other thread, linked in the OP above.
