A newbie with serious TV problems (1 Viewer)

Hello everyone of you!
First of all, great forum! Im going to enjoy reading it.
As you can see Im a newbie, and as a good newbie, I have some questions I need some answers to.
About 3 years ago my dad bought a huge home theater (Pioneer VSX-456 receiver, Technics SL-MC401 111Cd's charger, Technics SH-GE70 EQ and amp, Technics RS-TR272 deck, 5.1 Bose system (dont remember the model, but Ill be looking at the manuals) and some Technics Loudspeakers (don't remember de model either).
We mainly play PSX and watch DVDs and some Tv here.
Now here comes the problem:
The problem is that colors in the top of the screen diverge theirselves, and it looks horrible.
WHAT CAN I DOOOOOO
Any kind of help will do.
Thanks
Walter

p.s I cant post a picture of the problem right now, since I dont know any good free hosts for pictures. Any good ideas?

Not much unless you want to call in a tech to adjust convergence, or learn how to do it on your own; you'll need a service manual and crosshatch patterns for the tv.
