Maybe I missed it but whats the chassis ## ?
IIRC the vert controls are on the module with little extention
shafts. If there is a large adjustment needed UNLESS the pot has
a bad spot or someone messed with it it HAS a problem.
You should do the vert next, it may cause more damage.
BTW your voltages are OK, its not unusual to tweek the
grey scale a little especialy an old set.
Be sure when doing your doing the final set-up the set has
run a few hours & is nice & warm.
