Thanks guys. I've cleaned several chassis this way in the past, they come up like new. I do always make sure I seal the anode cap and top of the flyback to avoid any ingress. I wouldn't mind betting a cap or two will have spilled their guts too looking at it.

The Sony manual does outline the process, though I can't for the life of me work out some of the language or illustrations. I scoured youtube but no one seems to have documented the process which I find odd. Maybe I need the services of @Welsh Anorak for this bit?
