    Have a Toshiba color tv model CX36H60 Chassis TAC 9813 that started loosing the vertical raster intermitently.
    Fixed several cold solder joints and worked ok for a while.But now the vertical raster is totally gone.
    Need schematic,components location chart or any idea about fix for this problem.
    Regards

    Horizontal output transistor.
    Check the resistors and capacitors connected to it in case they were also damaged.

    Cold solder joints

    I pulled the whole TV printed ckt bd out (AGAIN)and inspected troughly the solder joints and found several dubious joints.Also found a loose capacitor by the (vertical) ??output transistor and resoldered.Last but not least resoldered all 3 big IC's on the board.All OK now.

    Thanks

    Good work. Especially without the schematic.
