I recently bought the 40PFL5507H/12, and had it functioning correctly for the last 20 days, till yesterday when the picture suddenly freezed and the screen turned off. Since then, the only sign I get from the TV is the red standby light, which blinks twice every 5 seconds. I tried unplugging the TV and I also tried it into different sockets in the house but the problem still remains the same. Anyone has an idea of what might have happened???
