"Why does my Panasonic LCD TV turn itself off after 2 seconds"에 답변I 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.
"Why does my Panasonic LCD TV turn itself off after 2 seconds"에 답변I had the same problem and fixed it. In my case my older TV had dust stuck in the fans. I disconnected the TV, took it down from the wall, placed it face down. Instead of unscrewing the many many screws (some of which were stripped), I took a hair dryer and blew air on the top vents with the fans below. Dust and dirt blew out. I did this for 3 minutes/fan until no more dust came out. The replaced the TV on the wall, reattached cables and voila it works and does not shut itself off Richard
