I knew about that method, Damon,...but,...I'm not a big fan about soldering
hard to get at locations when they pass the tapping test. Also, I don't like
to disturb the yoke position on a set that has near perfect convergence to
start with. If the Red yoke connection goes bad, I might HAVE to do it your
way, cause there is less space to work at on the right side.
I also don't believe in replacing e-caps, and (especially) resistors that
test good. Even though they have a history of going bad. I don't get anymore
recalls then any other, above average tech does.
IMHO,

>> Here is a proceedure I figered out, to solder the yoke P.C. board
>> connections on these Mits PTVs:
>> Hope it helps someone in the future.
>> ***********
>> 1. Remove speaker grill cover, and work from front of set.
>> 2. Remove access cover behind speaker grill cover.
>> 3. Locate the yoke plugs on the yoke P.C. boards, on all 3 CRTs.
>> 4. Wiggle them to see which one is making the loss of vertical deflection
>> trigger the video shutdown cks.
>> 5. Remove the 2 plugs from the yoke P.C. board.
>> 6. Position a small 3" x 6" hand mirror, at an angle where you can see
the
>> back side of the 5 pin plug, on the P.C. board.
>> 7. You will see a ring crack around the top 1 or 2 vertical pins of the
>> jack.
>> 8. If the gray plastic from the housing is blocking your view, just cut
it
>> away with a pair of dykes.
>> 9. Now take a 35-45 watt pencil iron, with a pointed tip on it, and bend
>the
>> tip at about a 30 degree angle.
>> 10. Now simply solder the bad connections on the yoke plug as needed.
>> 11. Re-install covers on front of set.
>> 12. Collect for you service call.
>> 13. Smile all the way to the bank.
>>
>> Have a nice day,...and have fun on your next repair of these Mits PTVs.
>> Where there is a will,...there is always a way.
