Television and Home Theater

Im lost . i have replaced the stk392-110 ic's and nothing has changed. the resistors seem to be fine also. the red convergence is all over the place and the cross hairs are blurry. green and blue are good. i have been in the service mode and went into the convergence fine mode and the red graph is blurry,distorted. if i try to move the checker board screen to straiaghten it out it keeps telling me the limit is over. i really cant explain it but i can send a picture. please any suggestions would be grately appreciated .

T.V. won't turn on does not have the blinking light I have already had that problem replace the capacitors about a year ago. I can reset the T.V. but still won't turn

When watching my tv on satellite after a few minutes I hear a "pop" and the screen goes to blue. If I switch to (or am watching instead of my dish) regular antenna dtv the picture is there but the horizonal & vertical both run at the same time and there is no audio except a steady "whistle" "errrr" kind of sound. Also the menu selection is on the screen as it is whizzing by.
