Query: If you buy a Magnavox buy the extended warranty, you'll need it.

We started having problems within the first few weeks. The picture would cut off, randomly, for 20 seconds to 2 minutes. I called Magnavox a few times, I was told to run updates which did not help (I just learned to deal with it). After about 14 months the delayed start, after pressing power, became longer (2-4 minuets). As always I downloaded updates, no help. By 19 months I had to press the power button and hold for several seconds then the power indicator light would come on and eventually the TV would come on. At 21 months the TV stopped working, would not come on at all. I called Magnavox and was told to take it to a repair shop.Twenty-one months too late I went online to research problems with the model/brand and most of the comments stated "Magnavox TVs typically only last 20-24 months". I wish I had researched before I spent $799 on the Magnavox 37MF231D/37. Research 1st.
