Toshiba Light Engine vs Lamp?

Vylent24

I have a Toshiba 56HM66 DLP, After about 3 months of use, it started getting a "negative" looking effect. I got a Toshiba certified tech out and stated the "Light Engine" needed replacing. It does not qualify for the "recall" as seen in various posts and is out of warranty. The estimated cost to repair was about $900 of my hard earned money. I contacted an online parts distributor PartStore. They stated it was not a lamp but the part I needed was an "Optics Block 95.L" which I assume is the Light Engine with a cost of approx $365. So here are my questions, can anyone confirm if this is correct? Is the Light Engine different from the Lamp? How difficult are these to replace yourself? Does anyone know if there are online instructions in replacing these? I went with the Toshiba DLP because I have had very good past experience with an older RP and CRT but since the purchase of this one and the crappy Toshiba technical support, this will probably be my last. Any help would be greatly appreciated. THANKS!!!!
