JVC AV-27920 horizontal sync loss problem

[Greg Delgado]

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
