apologies if this has been spoken about before. I just called some people who deal with extended warranties with DLPs to ask whether they actually cover the costs of replacing bulbs. as a noob to DLPs they said to me they'd only replace equipment inside DLP screens if it wasnt something a typical consumer couldnt replace themselves. I was wondering how easy it is to replace these bulbs? Also where would I get replacement bulbs for a Samsung SP50 screen?
