The two parts have the same pin-out but the 120 can handle more power. If you install the 110 version, expect it to fail rather soon. If you call the distributer from whom you recewived the parts, they will likely exchange them for the correct ones for the difference in cost plus shipping. It won't hurt to ask. Check in the area of the ICs for open pico fuses or open low valuied resistors. Either can cause the problem that you are seeing.
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
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.
There are two major possible cause. The picture tube or the power unit. I had the same problem. Fortunately it turned out to be the lesser of both evils. The power unit. The repair shop was able to rebuild a power unit for less than the price as purchasing a 32' LCD TV. Less than $400.00
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.
