I too experienced the same malfunction after 7 months. The LCD screen now has lines across it - no picture at all - just audio. [........]. I've had TVs for over 15 years with no problem...I expected a lot more from this product. Avoid!!
It looks great in my new kitchen, but after only 8 months of using it for 1-2 hours a day for 3-4 days a week all I have is lines on the screen. Still have sound, but unable to see picture. Warranty is only good for 90 days.
