It is symptom of dying lamp and tv requires new lamp.
Existing lamp in tv has reached to end of its life span and causing that problem. If lamp has not been replaced in last 2-3 years, just put new lamp in tv to get it back in business.

Your thermal fuse has popped and needs replaced. This TV has a service bulletin regarding this issue. You should contact Sony for the replacement part/kit.
