    Samsung DLP TV HL61a750 led lit... dmd replacement?

    Have a question about the replacement chip. Ebay listings for the chip show 1910-6103W as the "base" for a variety of sets, this one included. My question is about the "sequence numbers" there after. A lot show "02z..." or "54z...". The one that I thought that I purchased was "02z.." but it wasn't when it arrived. I didn't take immediate note of the difference UNTIL after about 5-6 hours of viewing the "post install display", the chip appears to have failed on the right side with significant "mirror issues". The original chip had 3 stuck white dots on the left / center. I put back the old one (got my 3 dots again :-( ) and am waiting on the sellers comments about what to do. :-(

    That's when I started looking at the listing (and others) and noticed that the chip that I got has an "E" between the base numbering and the "sequencing". I don't see this designation anywhere in terms of meaning. Hence the question. What up with this? How about "Experimental"... :-) or how about "Exception" meaning "manufacturer reject"... :-( I see one listing like this now... :-(
