Re: Sony KV-A2942U very soft focus in middle of screen
Hi
The screen shot explains why the centre "focus" is poor whilst the edge seems fine.
It is because the horizontal tilt and amplitude dynamic convergence requires setting up.
From the screen shot, static convergence looks fine. Any edge mis-convergence can be corrected by the permalloy strips.

What ever you do, you MUST read the service manual to get a hang of the dynamic //static convergence in a domestic Sony TV. It isn't difficult but without the instructions in front of you, you will end up wishing you had left well alone.
