Question about Televison & Video
Most likely there are some parts that have become thermo sensitive with age. Many times electrolytic capacitors become thermo sensitive as they ware down.
The parts that are going out of spec are probably causing some kind of fault that the set's uPC sees as a fault and puts the set in to protection.
The service tech will use a heat gun and liquid air also known as "freeze spray" to cool and heat the suspect components to trigger the fault, and then reverse it. Once the parts are found, they can be changed.
