This is a convergence problem. It happens to all big screen rear projectors. The convergence output ic's need to be replaced. I would let a repair man do this.
Sounds like your convergence chips are shorted which would make the set shut down. Its also possible that the flyback has failed but because the first symptom was the 3d look I would start with the convergence repair.
Here are some of the most common symptoms.
Screen looks 3D One or more colors can't be adjusted when using the convergence menu. Screen is bowed in but stationary. No audio or video - typicaly occurs after having the distorted color problems listed above.
Solution: You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.
