Possibly other problems on the deflection board your scaned derived voltages are probably missing when a flyback goes it almost always takes out other components or b+ voltages/g

Start by going to a good college and studying electronics 101 followed by electronics 102, math, algbra, etc, until you get an engineering degree. Now as for the dark purple and blue. It sounds as though you have a picture tube getting weak in the red gun and unless you can turn the red gun up you may need a new set. Anyway, good luck and have a great week

red picture tube broke at the yoke received this tv for free. worked for the first night next day the red was going on and off for a while, then on super red with  a curved picture when it poped and shut down. I said to myself I can fix this ,I went to school for this kind of stuff. Proceded to take back cover off and take look,  after i checked this site for clues I pulled the red plug with blue wires and tried to turn the set on. When I hit the button for the third time I almost soiled myself when  the neck of the picture tube fell. I also noticed what must be coolant had squirted out the breather hole and ran down the side onto the circut board below and looks like it may have done some damage. there is one small greenish-black spot size of a pea going under a capaciter and the board looks wet in that area.Why did this happen? One more thing,the tube part number is P16LFM00RFA(TU)  what is the diference of this # and that # with (AU), and what about using a tube from a green or blue  and change out the lens? (with matching #'s from blue or green).
