I've been struggling with a failed Samsung ps64e550 for the past 8 months and have decided I'd better sign up to be more accomplished in resolving my own issues.
Late last summer the tv switched off and showed no signs of life, I worked out a fuse had blown on the power board and replaced it, it blew again straight away so decided to replace the power board. Now with a new power supply it is power cycling and I noticed some initial red 'snow' on it's first run.
After watching it switch off and on after 60-90 seconds a few times, I noticed some loud electrical noise from the power board so am not game on switching it back on for fear of blowing the new replacement board.
From my reading it'd possible the Y-main board also needs replacement, however I don't want to buy another and find out it was the buffer or something else that's the issue. Would anyone have some advice on how I can verify further the cause without replacing all the boards one by one.
Thankyou
