Television and Home Theater

We moved the TV from one location to another.  Since then we have had problems keeping the red and the blue lines, lined up.  We hired a man to come up and hook everything up for HD and had it working good.  But a couple of days later same problem started in.  Also it looks like a fish bowl affect on the screen.  We can line up horizontal but can't adjust vertical.  Thanks for any help.

Sanyo model DS36930  Has no video,has sound and hi voltage.  Screen voltage is essently zero  measuring on the crt board but okay when board is not attached to CRT.  Any direction here?

I have a Samsung HCN4727W (a 47" widescreen, HDTV-ready RPTV) bought in 2003, and the screen went bad 2 weeks ago. The screen looks like a lie-down hour glass. And the red and blue convergence didn’t work at all in convergence adjustment mode(Mute183) in service mode. The centers of red and blue test pattern are about 0.5 inch away. It looks like 3D movie without glasses.
