Check for components that have become thermo sensitive. You will need some
liquid air ( a product called Freeze Mist ), and a heat gun to troubleshoot.
Carefully heat and cool the suspect components. Start in the audio sections
of the set.

I would strongly suggest that if you are not trained and equipped to do TV
service, you should give the set out for this type of service.
