Finally found some time to get back to this. It has been to long.
Well I was thinking about what ctc17 asked me about there being no green.
I tested the 21fj when I first got the set and only the blue gun looked weak it would get better when the filaments were on for about an hour and then re-checking. This was with an old beltron tester. I got a sencore 7000 and re-checked the tube about the same no g1 or hk shorts,cutoff passed,and emission hi tracking passed.
Next I found a rca test jig 10j106 and tried the chassis on the bench.
I had to make the crt plug adapter from tube base pins and a brightner socket
but it works. I have color on the test jig just turned a16 1 turn in and it locked. Great I have color-----but when I hook back up to the 21fjp22 IT is still the same
as before color is all wrong.
I found pin 6 of the crt socket loose and tightened it (no good)
The crt passed the tests on 2 different testers and the chassis makes color on a test jig but they wont work together.
