I did, did a search in this thread and came across Dmusoke's post where he went thru the same thing. I don't know how many hours, but I bet it is over 10k, my wife is a teacher that does not work summers, so the TV is on for most of the day, and I have had my 151fd since spring of 09 if I am not mistaken. I love this TV, the PS should be here today and my brother-in-law is coming over to help me bring it down from the wall and hang it back up when I am done replacing the PS.
Thanks guys for providing some links to the service manual, although I don't think I will need it, better to have and not need, than to need and not have.
