I had the same issue with a smaller Panasonic TV and was able to solve the problem. I unplugged the TV and removed the back by unscrewing the screws that held it in place. The problem was with age, dust had accumulated in and near the fan. I used a hair dryer to blow air which sent the dust flying away. I did not have to come in contact with the fan. I then replaced the back and the TV worked as it should.
