Testimonial: "I was in the trade until 1999 but have had no experience of LED displays. Like you I have gone for the back-light board. there 2 flashes from a component on this board when switching from standby to on. I am looking at this TV as a favour for a friend so I don't want to go down the road of trying to source components. Friend said that display did come back on for one day so I was hopeful that this was a dry joint but maybe thats a thing of the past! Thanks for your help"
