Zenith SM2745MK86 Whites are blurred

[cmartin]

I have a 12 year old Zenith SM2745MK86 27" console TV that has started losing it's sharpness. Specifically the white is blurred, most noticable in the score box of a sporting event (i.e. while watching football the score and time in the upper left (or right) corner is blurred to where you can't read the digits). It seems to depend on the background colors and there is no 'peak white tearing' (over mod). Does anyone have a service manual for this set or detailed info on what adjust can be made to tune it up? I know it is older and I have already replaced the set with an LCD, but i still like the features of this set and it would make a good set in our guest room.

Thanks for any help.

On the back of the set you'll find 2 holes. One is screen adjust and one is your focus adjust. Adjust your focus control.

I couldn't find any adjustment screws (holes) on the back of the set. I took the back cover off, and still don't see any place to make focus adjustments.

I did find a AGC, AFC, AUD, controls on a box set in there sideways next to the tuner. I know that AGC is gain control (don't nned to tweak that), is the AFC 'Focus'?

It's on the flyback, it has the red wire that goes to the picture tube.
