so I have an HLS5687 bulb DLP. for a while now it has had a random color flicker. because of where I live samsung hasnt been able to get anybody out to service it and they said they will replace it with a HLT5687. i've been reading this thread and quite a few other reviews and cant make a decision. it seems like ive read nothing but horror stories about getting DOA TV's, the halo problem, bowing, etc. with me living in a zero service area i dont want to go through 2-3 TV exchanges before I get one that works.... my main question is how does a correctly working LED TV compare to its bulb counterpart?
