SOURCE: what does it mean when my plasma tv turns off by
Basically when it turn itself OFF automatically all the time, the TV goes into "Protection Mode". This happens when there is a damaged circuit board inside the need to be replace and turn itself OFF to protect the other ones from being damaged.
A TV service tech will have to look at it to find out which boards need to be replace. There are about 7 different boards in your TV that would cause this problem.
