Thank you for your advice. I opened up the back of the tv and the red and blue worked but the green wouldn't go on all thew way. How complicated and how expensive is it to repair the green gun? is it something i could go buy something for, uninstall and install myself?

HI, thank you for visit fixya.
Common problem on this set .
Picture tube liquid is dirty.
Mostly in crt green and crt blue.
Do you have electronics skills?. If so, open the TV ( back cover), you will see green,blue and red gun. After turn on your tv, select any channel or video signal, cover with piece a paper two guns at the top ( any), and see how look the picture in the front, try one at time, ( press menu on remote control and see leters-clear). I am sure the green and blue will be no clear. all the time red tube is fine.
REPLACE COOLANT LIQUID PROJECTION ( solution).
I will be here for any quetions.
Red color gun has failed, which will make the picture over saturated with the other two colors(blue,green) the bad news is the three color guns need to be replace in a set(all at the same time) because if you only replace the red it will over saturate the older blue, green guns then your picture will be mostly red.Unfortunently in most cases it's not worth the investment, better off to purchase a new tv. Good luck !
Several failures can cause a red picture but it sounds like if you are connected from the source with component video cables(red,blue,green)you may just have a bad cable,but you may have had a blue and/ or green projection gun failure,which would cause the red gun to over power the other colors(blue/green), if this is the case definently not worth the cost to repair, you have to replace all three guns at the same time costing $500+ to repair, invest that towards a nice new LCD panel TV. Good luck !
If you are asking about Guns in rear projection tv then answer is No. Rear projection TV has 3 Guns (CRTs), red-green and blue and each gun has its unique color phosphorus coating to produce its mono color (red /green /blue) and these are not interchangeable. Need further info, let me know.
No its a tube and not a bulb. If thew line is green then theres an issue with the red and blue as the green is stationary on most sets unless thers a green centering ? Its a componet on the convergence board thats bad or going bad but if you replace any components on the board most likly your gonna need to do a convergence alighnment I would let a pro handle this repair unless your an experineced repair tech Good Luck
