This is a bit late on the reply... but if you want to improve focus I am pretty sure that is a mechanical/manual adjustment thats done on the tubes themselves. I have a Pro 520HD and I havent had to improve sharpness, just make the geometry better and fit the whole image on the screen.
There is service menu functions, for the life of me I cant remember how to even get back into them. The service manual for the TV should be online somewhere which will tell you everything you need to know to fix (or destroy) your TV.
The manual should be the same for the Pro 510HD, 520, 530, 610, 620, 630 etc.... Pretty similar all together with minor differences, size being the main one.
Good luck, they are awesome TVs (or as pioneer calls them, HD Monitors)
