Rated 5 out of 5 by from Excellent TV I love this Smart TV, I have my Netflix and my RedBox through Verizon. I would recommend this product to anyone. I also Sound Bar.

Rated 5 out of 5 by from Excellent Smart TV This is the first smart TV I have owned, but not the first I have seen. My TV is 55" LED Smart TV and it came with a Sound Bar to match and the two combined are perfect. The TV came with a Wifi card in the box for wireless connections.The TVs weight for the size is astonishingly light for its size. I am a gamer at heart and the TV handles the harshness of video gaming for hours on end and also handles the ease of just listening to Pandora or watching Netflix from the TV itself. I really enjoy this product as it is the best TV I have ever owned.

My TV (55LN5790) will come on with audio and video. After about 5 minutes the video will go black and the TV will stay on with only audio. How can this be fixed or what part can I get to fix it myself?
