    Hi, just wanted to pick up any thoughts on this.
    Original fault frame IC (TDA8171) overheating and frame
    cramping/stretching as it warmed up- there was slight pincushion distortion
    noticable.

    Changed the IC- (don't think its a cheap pirate version- but Its not a
    Mitsubishi supplied part). Haven't changed any nearby caps- not had problems
    with them on this model series, none are leaking or check leaky.
    Frame is basically correct but still have the pin cushion/corner correct
    problem.
    can only get a respectable straight picture when the width is taken up a
    long way.
    Perhaps it is a slighly dry/faulty cap or could it be the IC version?

    regards
    Andrew
