I had a similar experience with a Philips. The set I worked on needed 1 or 2 convergence IC's (black multi-pin, mounted on heat sinks) replaced, a "fix-kit" which he got on the internet. That did fix the convergence issue.
The fuzzy picture may be the result of cooling fluid in the lenses being polluted with microbial growth, especially on the CRT faces of blue and green.
I would first try cleaning these out before spending money on the convergence issues. We got the cooling fluid from a local electronics distributor.
