I've been reading this forum for a few weeks now and many thanks to everyone who posts as the opinions given are invaluable when looking to spend the hard earned. I am the now proud owner of a 42PWD7 (bought as a bundle with Composite/component boards, Tosh sd44, wall mount, etc) I've got a couple of bits that I can't settle on.... Should I drag back the levels while "running in" the unit?? and if so for how long?? Read that some people do, some don't and some do for 200 hours?????? Also, looking to get the plasma pro tuned but how long should I wait before the levels have settled enough for me to get the best from the service??
