Sometimes while watching the television, my Sony KF-42E200A automatically gets switched off. The indicator light flashes in red. It flashes 3 times for 3 sec & the waits for 3sec and then again flashes 3 times in another 3 sec. This continues. The T.V. does start again after around 5-10 min. This problem happens sometimes.What is the problem with my set. Kindly reply to me on my email id flabby_flyboy@yahoo.co.in
