Is TV Repair A Good Profession
If you have an education in electronics and a strong background in math and physics, a career as a network cable technician may be a good match for you. TV repair is best done by a trained professional, one who has been trained and certified by a professional TV repair program. Direct experience in the field or a repair facility is excellent training for a TV and video repair technicians. With LCDs, Plasmas and HDTVs ranging in the thousands of dollars, having a reliable TV repairman is not a bad idea.

You have two problems, a horizontal pincushion problem caused a capacitor or resistor in the horizontal section and a weak old crt,. One such example is that of multimeters, which can detect short circuits, bad capacitors, and blown fuses by measuring voltage, current, and resistance. A slow turn on does not sound like a capacitor, more probably a power supply or a bad semiconductor.
