Indication of 7 flash from led at the front panel.Try to disconnect the FBT from HV splitter.A short HV burst appeared on disconnected output of FBT after power up. No short found on HOT . Any idea.....Thanks in advance George

I can't find this cap 681 2k. I replaced the cap C5039 682(0.0068uf) 1.2KV at HOT but no effect.I also replaced a cap at HV C5039 822(0.0082uf)also no change.I paralel another 0.0066uf across C5039 and the set didn't shut down and work's like a charm.I can't explain why so capacitance sensitive this HV snubber capacitor.
