Greetings, When I turn on my 40H80 I will occasionally here some clicking/poping type noises coming from inside and then the TV powers on with the screen going into 4:3 mode. It doesn't reset my screen preferences and once I switch it back to theaterwide via the remote all is well. I am concerned that this may be symptomatic of a larger and possibly more expensive problem in the future. I would like to have a tech repair it and was hoping that someone else may have or had this problem and can tell me what to tell the repair tech prior to the service call. Thanks in advance for any assistance.
