There is conflicting testimony on this. Originally Mitsubishi blocked Samsung receivers from using their converter. Which ones and if at all it can be done might be an expensive experiment. Don, what was the approx. cost, if you can say.
I like my HL-T5687 because it uses LEDs instead of a bulb and color wheel. Had an HL-S5687 with a noisy wheel from the prior year. After several "replace" failures and for money, Samsung upgraded me. I replaced the red LED a couple of months ago after 4 years, just over $100 with many hours on it, maybe 10000. I would have had several bulb replacements at over $100 each because I leave it on a lot. It has no wheel. The red LED has 24 fins vs green of 14 and blue of 10, as I remember. So it must get hot--the internal chip leads were melted. There is an AVS board on this model > 14000 posts IIRC. The picture is superb in Movie mode, unfortunately the hardest on the red LED. Checking hours of use resets all settings so I'm not checking it.
