Pink hue picture denotes the absence of green colour. Check the green video output transistor for open. It can be easly recogansized by taking the voltage at the collector point of that transistor. It will be high, almost equal to its supply voltage. Measure the base voltage of that transistor also. If there is no base voltage the symtom occurs. if it is so trace the track and reach to the green output pin of the related ic. If there is also no voltage, Ic may be fault. on the otherhand check the green cathode of the CRT is ok. It is quite easy. Detach all the components related to that pin, or make a temporary cut to isolate the green cathode. The switch on the set. If a green colour [High intensity] perists, the CRT is ok. You can check it in an other way. Take a 2W resistor fo value 470k or more, connect its one end to earth point, and other to the green cathode pin [Just Touch and Out], a green screen will flash on the screen. If these to checks fails, CRT is faulty.
for the color problem,most likely you do have problem with loose contact of components from C-board ( small board connected at the back of CRT "picture tube" which drives every color and size of the screen)if you have knowledge with soldering electronic component parts, resolder this board and also check main board for possible loose contact.
Problem 1. Color patches at lower corners. These are caused by magnetic sources close to the TV. Do you have any Speakers close to the sides of the TV? Are they Magnetically sheilded? No? Move them away from the TV. Problem should then resolve itself in a couple of days.
Problem2. Screen Slumping. Most likely a problem with the Pin cushion correction ckts. Get a good technician to have look. cost should not be much. Under 100$ plus Technician fees.
