The light engine in my HLN507 (v209 4/03) was replaced yesterday after complaints of a dead pixel OOTB and severe internal reflections. I waited 2 months for the repair but the wait has paid off. Though not entirely gone, I am pleased to report that the new engine significantly reduced the internal reflections. However, on initial viewing, it appears that I have sacrificed a bit of PQ, but the trade off is worth it to me. I must add that Samsung customer service has been awesome and has really gone the extra mile to make customers happy and resolve this issue.
