50 LCD HD TV

- I just bought a Hitachi 50 inch plasma TV, and is it better to shut it off, or to leave it on standby?????????
My wife, I, and my son have ben debating about this ever since it was delivered yesterday morning. We have heard a story from a friend with a 70 inch plasma (mind you, this was 3 or 4 years ago) where his tube broke in just 6 MONTHS!!!! Sony told him that it was because he would leave it off then turn it on, and he should leave it on standby at all times. Is that still an issue now that today, plasma tv's work for about 10 years???????????

A Won't matter. Today's TV use push on switch which mean your micon is always in on position waiting for switch command. It is simmiliar with standby position the diferent only in stanby LED for stan by is light. If you want real diferent than you need to unplug the power cord in this way your micon won't be working as well. But it's not practice.

- I have a 50 inch Hitachi LCD projection TV, however, there is a pink color in the middle of the screen.?
I am not sure if this the beginning of a problem. Can this problem be fixed by a do-it yourselfer?

A Based on my ex this problem usually comes from the optical block. it can be only dust covering on of the three LCD, can be one of the dischoric mirror melt or one of the three LCD crack.because of over heated. The worst case you must replace the whole op block, which is not cheap.
