Hi there, I have a Sony KX-27PS1 which has a bit too much vertical overscan for what I would be using it for, I was just wondering if anyone has the service manual or knows of how to adjust it.

Thanks in advance!

Assuming it's similar to the KX-20PS1, then the height adjustment will be inside on the Deflection Circuits PCB. It should be marked as V-Size (I think).

Thanks AndrewM, I had a look inside the other day and remember seeing three pots, one marked H.Stat which was on the C board (R.G.B Out), another one marked SCRN and another marked FOCUS on the T board (teletext apparently). I'll have another look inside and try deduce it. Cheers again.
