I found a high resistance trace once, connecting a coil, L702 at board
location K15. This is in the 26v supply, but it fixed a B&W problem. Go
figure.
Here was the post I made:
--------insert------------
Greetings.
This was actually a PTK169 but the whole lot ought to do.
Symptom: No color.
Fix: The trace between L4702 and C4705 measured 3K ohms. Installed jumper.
This trace is physically located at location I15-H15.
Background:
U1001p12 calls for about 7V, measured 6v.
Moving back to C2802 the +9 supply measured 8v.
Moving back to Q4704B 9v run, base was 9 instead of 10v
Moving back to the 26v run showed 22v, AC measured 6v
Power off set and measure trace...see beginning
-----------------end-----------
Good luck.

> I am experiencing intermittent loss of color in this unit. Have soldered
all the bad connections I could find, and flexing chassis doesn't affect. It
is probably a cap somewhere, but I was hoping to see if someone had a tip on
this before I went through testing all of the ones on this set. Thanks for
any help.
