Teac LE40UBFHD update. 2nd tv returned for refund used for 48 years - no joke

Teac LE40UBFHD out of the box had 17554 usage days thats 48 years. This TV lost sound 3 days after it had replaced the identical TV that had the screen fail, featured in another of my blogs. Teac took 9 days before i was refunded. i had complained waiting on the 2nd TV to be repaired. I had 2 identical TV's fail from different problems with 14 weeks. NOT GOOD.
