Television and Home Theater

i have recently replaced my convergence chips (1 day ago) and the red was now out of alignment.So we took the panel back out and cleaned up the solders more,and put it back togeher,(hooked all the wire clips back up) and after we did that we turned it on and all we seen was a green led light flashing on the board and it blinked for about 10 seconds and then the tv turned itself off,we tried it a couple of times and it kept happening.Can you please help me with this problem,i would greatly appreciate it? Thank you jonathan concerned hitachi owner 

My wife and I recently purchased a used panasonic 56 inch CRT television. The picture is fine but the alignment is slightly off. In other words, the projection is lower than it should be or does not fill the screen. For example, I can't read any text that runs across the bottom and there is a black space across the top. There does not seem to be a way to resolve it through the remote. I opened the back but am lost from there. How do I adjust the picture? I appreciate any help.

Hi, I've got a problem with my Philips 32" TV (model number is 28PW6515/05).

I bought it from a chap who explained that when it overheats you "can't change channel", but the fact that it wouldn't change "normal" analog channels didn't bother me because I have a Sky digital box, so I got it for a cut price.
