Hi guys

I am facing an issue with my one month Toshiba 39L3300 LED TV. Since yesterday, once or twice, there is a very shrill sound coming from the speakers for around a second or three, and the screen starts zigzagging (like in old CRT when we don't receive proper signal). After those few seconds everything becomes normal again.

It is very hot in Delhi here (40 degrees) and the TV is left on since morning in the drawing room playing Tata Sky Active Darshan the whole day will evening. Should I put on the fan in the drawing room. Could heat be the reason for this problem occurring. I seriously hope I have not received a defective piece.

Can LED tv's be kept on for 10 hours at a stretch?

Looks like interference caused by mobile phone don't keep any phone near tv or may be it is due to loose connection in power cord i am not sure.
