Hi,

I am slowly working my way through a few issues with this television and am nearly there.

However, does anybody know how to centre the picture horizontally on this set? I've tried to show the issue in the photo's attached. The whole picture needs to be shifted about half an inch to the left. Is it performed electrically or mechanically?

As this is a delta-gun tube with many adjustments for static/dynamic convergence, I'm loathed to start adjusting anything!

I have the circuit diagrams, but unfortunately not the full manual.

For reference, the picture tube is an 490DKB22.

Many thanks in advance,

Best Regards,

Adrian.
