Sounds like bad diode ad capacitor in pincushion circuit. Check caps and diodes around horz. out. Also yu can go to google search and enter make and model and it might list access to manual and a tip on exact parts.

    I really could use your help. I have the above Sony Trinitron that has an hourglass shape. The sides are curved in. All else seems ok. Thankyou.

      Check q530 for cold solder connections, or shorted. Also could be open c512 4.7mfd open and check coil L517 for overheated and shorted.
