I suddenly have two small white dots in the center of my screen .....Store that i purchased the television from says that it is the light engine going bad that is causing the pixels to stay illuminated...Of course I did not purchase the extended warranty! and they priced this part to me for $650 !!! Is there a difference between the light engine and the DLP chip? or are these one in the same thing? Mitsubishi wants me to pay a guy 100.00 to drive four hours to give "diagnostics and Estimate" and then they will consider whether to fix my television....no guarantees! Has anybody else encountered this problem with this model television? If so please any advice would be appreciated!!! I purchased this tv Feb of 2009 not even two years old yet!
