Power button Flashes

For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.

Won't turn off unless unplugged

Ther eis a stand by function on the Television. If you have the owners manual read about that function. Th ered light stays on because it is programed to come on a t a certain time. Go to menu and find the stand by function.
