We enjoyed this TV while it worked. We purchased it in January 08, had to have a service tech come fix it right away and then had to wait for Hitachi to send a firmware upgrade before we could use it. Two years later, it plays for a minute then shuts off. Hitachi sent another firmware upgrade, but the power won't stay on long enough to do it. Now we have to pay for someone to come tell us whether it's worth fixing or just scrap it because it's not worth fixing. Too bad. I won't be buying another Hitachi, I would suggest the Sony Bravia which we've been much happier with the picture quality anyway. Customer service at Hitachi acts like they get calls about this all the time. Seemed to know what the problem was but didn't tell me.
