The problem you are having is with your convergence amps your set uses STK 392-120's if you replace them you will get your convergence adjustment back, Philips part number is 932212344682

This is a convergence problem and can be repaired by replacing the two STK-392-120 convergence chips and adjusting the set with the original remote control
I have specific instructions for this repair from start to finish.
If the colors look 3D or if you can't adjust the blue or red convergence the convergence chips and resistors should be replaced. You can get a repair kit and photo instuction guide for this exact model from www.TvRepairKits.com. Hope this helps
You will need two STK392-120 Convergence ICs and about 4 6.8 ohm 1watt resistors. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures so you can do the job yourself. Here is the link. http://servicemanuals.vstore.ca/
No. your problem is related to the coolant in the green CRT has congealed with bacteria and needs to be changed. Thats what causes the halos and general poor picture and color quality. The blue should be changed also. The red for some reason doesnt seem to be affected by the bacteria problem. This is a common problem that happens with all projection TVs phillips and magnavox TVs
The green CRT coolant has congealed thats whats giving you the green halos. Change the coolant in the green and blue and your set will be fine. red is never affected so the red coolant should be fine.
Are the colors out of alignment and unable to converge back? If so its the convergence ICs need replacing. If the convergence isnt out of alignment you have whats called a pincushion problem. If you would like a link to where you can obtain the service manual for this model let me know.
replace ic chips pt# stk392-120 or stk392- 150 and there are 12 resistors located near ic clips pt# 6r8 ( color code blue - gray - gold - gold ) board location no#s 3149 thu 3160 if you look close you may find two resistors discolored as i found on my convergence circut board , also use heat sink compound on new ic chips , take your time to mark all wire connectors going to board from tv , also use .022 dia gage rosin -core solder and a 15- 25 watt soldering iron you may have to adjust the red - blue convergence afterwards my tv set is 3 yrs old also ( thanks holbert )
