Television and Home Theater

My Toshiba is almost seven years old.

Recently the picture has shown a predominantly geen colour and shades of grey are now shades of green.

The red, blue and other colours are well represented but there is a 'green mask' overall.

Is there a simple way to adjust the colour balance back to normal with this set?

 Any help would be much appreciated.

i recently picked up a old hitachi projection tv model #46UX12B manufactured August 1993 and when i hit the power button i hear a clicking noise from the inside and the power button comes on for a split second but then it shuts down. Anyone know whats up with this thing?

Hey Techs

need some help here.  Just bought a 37'' Sharp Aquos LCD which has S-Video, Composite Video, Component Video inputs.  I have (2) PC's that I would like to connect to my new TV.  I have done a little reading and saw I might need a RCA / VGA Component Video Cable.  But I am confused would I then use A monitor A/B Switch? and then hookup the both monitors to the switch and from the switch to the RCA/VGA component cable.  Does this sound right? thanks for your help and comments much needed.
