    I have Toshiba TV CF2666R with popular vertical problem.
    I exactly know what to do at this case. But I can't fined the C301
    Can somebody point me out where C301 is located?

    Thanks. Mike.

    Typically 2 or 3 capacitors near the vertical output ic and one near
    the jungle ic. C301,C305,C308.

    Still do not see the cap. C301.

    I don't know your model, but if it's anything like the Toshiba TV I
    repaired recently, you will probably find a faulty 2.2uF 50V cap near
    the TA8718 video/chroma/sync IC. One recent email from a fellow in the
    UK identifies this cap as C303. I don't know if his model is the same
    as yours, though. Perhaps you have the wrong circuit reference? This
    same fellow had an intermittent vertical collapse fault which he
    traced to dry joints at R323 (?) which is the current sense resistor
    in the vertical yoke circuit.

    This URL also identifies C638 (47uF 25V) as a possible culprit:
