Vu 50K 50" LED TV

文本:

I have 50" LED TV. Last 15 days I am having peculiar problem. In morning when I switch 'ON' my TV  then there is no picture at all. Black perfectly black ( No raster). However sound is OK. I receive sound if Set top box is ON. I checked HDMI connection and it is perfect. Without doing any thing, if I switch TV after 11.30 AM then picture comes and TV works perfectly all right. I switch OFF in noon time and evening again the picture comes perfectly all right. For last 15 days I am watching TV but morning time picture never comes alive.

I believe it has some thing to do with outside temperature. When Temperature rises then TV works fine. In mornings when temperature is low, the screen does not get any raster and no picture either.

Is there any temperature sensitive component or switching relay inside.
