Toshiba 56hm195

Purchased this TV in April and have nothing but problems. When using HDMI input, screen appears all green with purple highlights. Sears, from whom it was purchased, was here twice and has not been able to repair it. Last time, they replaced the motherboard and now it appears purple. Originally purchased it after research and magazine reviews. When it's working right, which is rarely, it has excellent display. Most of the time, it's not working correctly. I would never recommend this set.
