    Hi all. I'm repairing a set where the picture is torn apart sideways
    but doesn't roll vertically and has normal sound on all channels.
    Anyone encountered this before?

    Since the sound is ok , can I conclude that the tuner is ok?

    Would appreciate any tips on how to diagnose this problem.

    Thanks in advance.

    jagged verticals/horizontal tearing could be caused by the line driver
    decoupler capacitor - try replacing that first
