Toshiba - Stay away from this brand TV
46" Regza Tv - Model 46xv645u - Complaint
I bought a Toshiba 46" Regza TV in the Middle of 2010. The TV stopped working, no picture or sound in early-middle 2012. Nothing happened to it, I turned it off in the morning and came home afternoon and it wouldn't come on. There were no storms or power surges. My warranty had just ran out a month or two earlier and I had just gotten it paid off. Naturally, Toshiba couldn't do anything for me. I paid the TV repairman $75 to see what had happened to it and he said it was the mainboard; he could fix it for another $400. I hope someone will start a class action suit against Toshiba.
From all the investigation I have done I would advise everyone to stay away from Toshiba brand TVs.
