Television and Home Theater

My kids kicked a soccer ball into my TV and now the blue color is off. When I hit the touch focus button the red and green lines are straight but the blue line is curved. When it finishes the process I get a Touch Focuss Error. Any ideas as too what was put out of whack?

I did something very stupid today.  My Samsung HCL473W projection TV had convergence problem so I replaced the circuit board.  However, I forgot to unplug the TV while I was doing this.  I don't know what I was thinking.  After I replaced the board, when I turned on the TV, it won't turn on.  I hear clicking sound as if TV is going to be on then it does nothing and this repeats itself.  I do see the timer light on front of the TV is blink as well but it won't turn on.  What have I done!!

I have a Zenith ST2765S TV that was given to me (without a manual) and was wondering how to activate the AV jacks in the back so I can get my new DVD-R operating throught the tv. The manufacturor of the DVD recorder claims the ALL out put go through the AV jacks. Does anyone have any sugestions?
