Everytime I go to play one of my systems it usually broke. My 5200's controllers rarely ever work. My 1200xl keyboard barely works and my 800xl just blew up after replacing the cd4051be i.c. which I guess what was causing half of the keyboard not to work. Now half of the unit powers up. The power light won't come on but the monitor receives a signal that's scrambled. Any suggestions would be appreciated. Sorry. Wasn't paying attention when I posted.

Yipes!
Why not buy another 800xl, they should be cheap enough... You could even swap the boards if you like your case better..
