I purchased a Zenith r50z26 new and the TV was stuck in HDTV and could not choose standard or DVD format. I called Zenith and I was very rudely told to call a local TV repair shop. I did so to find out the local TV shop that Zenith recommended knew nothing about HDTV's. I called Zenith back and was referred to another local TV shop. The repair man came out and said there was a bad chip in the TV that they had to take it to the shop to be fixed. It has now been 2 weeks and the repair man told me it should be 7 to 10 days. The repair shop still can not fix the TV. So I called Zenith back to ask how long I would have to wait and I was told "You have to wait as long as it takes" I replied "Why do you customers get such poor service" and I was hung up on.BEWAREG .GILL(VERY UNHAPPY)
