Re: Blue and Green line thru center red shadow on both...
Most likely if the line is top to bottom you have no horizontal deflection
this could be caused by a number of things
but if you continue to turn it on it will score a burn mark on the face of the three crts
id call a service ctr in your area or you might try replaceing the deflection bd and see if this will resolve the problem
the problem could be a open yoke return cap but if you dont have the tools or knowledge this woulld be one better left to sme one more experianced with this
please let me know il be happy to try and assist you further

You will need to replace your two convergence I.C.s.They are two large
IC mounted on a large aluminum heat sink.Replace both,look for any
burned resistors near them,replace those if needed,and readjust your
convergence. Good Luck
This sounds Like the the coolant for your piture tube has become cloudy and needs replacement (usually blue or green tube - thats why the image seems ovrely red).It's a big job (labour wise) since completee dissassembly is required ($200-300). It can be done youreself - check out TVrepairkits.com to get the coolant and instructions.
You can confirm that this is the problem by dissassembling the unit to the point where you can view the face of the CRT's (red green and blue) directly.
TV shows large red spot in middle of tv when dark show are on, you can see it more. Now blue spots on upper right side too. Spend way to much on this tv to have these kinds of problems only after 3 yrs.
Most projection TVs have an option to refocus. For example, my Sony rear projection TV has a button on the front for focusing the lamps. Try finding this button or option in the menus with your remote.
Projection TVs actually use three lamps, one red, one green and one blue. These need to line up exactly in order to form a good picture, and when they come out of focus, you see the edges which sometimes has the effect of a 3D image when you aren't wearing 3D glasses.
Hope this helps!
