No... I don't mess with electronics. Unfortunatly, my father was a TV Tech for close to Fifty years but had passed away some time ago. I would like an answer and an estimate. If I need to make an appoinment, I will.
Thank you for the reply.
This problem is one that is common with your set, and any DLP that uses the Texas Instruments "DLP" chip in the Light Engine. The DLP chip which contains thousands of tiny mirrors on it is the culprit, and each spot that you see, is one of the tiny mirrors failing. The problem will continue to get worse until the DLP chip is replaced, and there are no settings you can adjust, etc. that will fix the issue. The cost of the chip itself is around $250, and the cost to replace the chip is around $200, which unfortunately makes this a pretty hefty repair. It is fairly straightforward for a Technician to do this however, and the set will likely give you another good 5 years of service.

Is this something that can be done in the home or does it have to go "to the shop"?
