    I’ve just had my Panny 32txpb50 changed because of a mark on the tube , however the replacement suffers from imperfect Geometry unlike the Original.

    The Bottom left of the screen bends down about 3 –4 mm and the top left bends up about the same .

    My Question to all of you is , Would you consider this to be reasonable or should I demand another replacement ?

    As a 2nd question , how would you rate the Geometry on your set’s ?

    A full replacement may be overkill, 5 minutes with an engineer may well fix it.

    My current Philips 32PW6506 seems (so far) to have no geometry problems. The previous one had a slight narrowing on the left of the picture (as well as a pink tinge), and the Thomson 32WR25UG they both replaced was written off for having an unfixable tilt/rotation to the picture.

    I spent ages changing some for the geometry settings in the service mode to no avail .
    I tried Trapezoidal adjustment , top corner,bottom corner , vertical linearity etc etc but nothing would touch the downward and upward cure in the left hand bottom and top of the screen (RHS is ok)


    this deflection is about 4-5mm , this I think is too much

    I was told by an engineer that up to 5MM is 'within specification'.

    I heard it's about 6mm , anyway I regard this as too much especially seen as it's in the center of the screen . I could accept it if it was at the side or corner's .

    I blame Panny quality control

    Had an engineer do mine under warranty (Tosh) it's great now. He took the back off and fiddled with the tube position.

    Get one out if it bugs you.
