Title: 47ln578v back lights.
Post by: bonesy on October 15, 2016,08:21:48

Just re- lamped another Lg 47",this time one of the old LED's had burnt up the P.C. B.which in turn burnt the white plastic backing sheet.I cut out burnt section & glued in a fresh piece of plastic from a scrap screen.I didn't want to run the risk of a dark area showing through.All good at switch on.

Dropping like flies these are, 32,42 and 47's, I'm going to look in the service mode and see if the maximum backlight level is adjustable. You can tell customers till you are blue in the face but they won't listen.
