Television and Home Theater

I have a Magnavox 26 tv in my office and sometimes the tv works fine but more often than not, the sound will come on but no picture. So, if I go and smack it on the back, I can here a little click and the tv will flicker on and then off again, I keep repeating it till it stays on. There is a definite link between the click sound I hear when I hit it and it turning on.

Any ideas?

Thanks so much.

I have a Sony KP-57WS510 (57' projection screen) that now shows 3 ghost all different colors.  Depending on where you look the ghost maybe be all to the left if you looking at the leftside or to the right on the rightside,  the middle is a little blurry with all 3 ghost close to the normal picture.

What is the problem and how can this be fixed?  Hopefully its something I can fix, with some helpful instrutions from y'all.

Appreciate any and all help,

I have a Toshiba TP55E80. The problem is with the bottom part of the screen.  It is bowed from the left side to the right side. I tried adjusting it with the controls... with no help.  The screen at the bottom is double vision as well as the color. The bowing is from the left to right side. I assume this is a convergence problem? Does it require inside adjustment or replacement of parts? Is this something I can do myself?

I cant afford a new tv but would love to fix so the kids can use it.
