They usually aren't worth repairing. I've found that often even used DMD chips are worth more than the projectors they go to. Actual replacement is fairly easy, but it requires a lot of disassembly.

I done one in my 57 inch Samsung. I got a new chip for $160 and it only took about 15 minutes to replace. It was cheaper for me to replace the chip than it was to replace the tv with one of the same size.
