Re: Blue/Green on edges of Panasonic HDTV CT-36HX42
Rear projection TV is light emitted and therefore can be fixed by a lamp replacement. I know the replacement's can in some cases be more expensive than a new model. Search the web for lamp replacement based on your TV model to get an idea.

I have a Panasonic PT-47WX53 rear projection TV and the picture was pretty dark for the last year but for game it was OK but know the blue is out of sequence, do I need to change the lamps?
And where to find them?
What you have there is referred to as white balance... The Overall White Balance May Suddenly Change And Become More Red, Green, Or Blue Depending On Which Crt Has Been Affected. During Turn Off A Crt Might Arc, Causing D304 (Red), D331 (Green) D361 (Blue) Damage And Leak Changing Cutoff Levels. Replace Diodes With Panasonic Kit # Txask02gser. Kit Contains 3 Diodes And 3 100k Resistors. Install New Diode And Resistor In Series In Place Of Old Diode. Install Annode In Crt Socket Where The Old Annode Was. Then Connect Resistor To Cathode End, Other End Of Resistor Goes Into Pcb Where The Old Diode Cathode Was.
A job like this in my shop we charge $280.00 dollars plus tax which includes the kit... Also a pickup/delivery fee if we have to go and get the unit...
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!
