I assisted in a quick-and-dirty today o a PG 6100 (I think, might have been a 9100.) Several of the alignment and convergence controls do almost nothing... nothing like the range I'm accustomed to in my experience owning a 9100 and 9200.
The F board looks to have been repaired (traces from deflection connector pins to adjacent pad had to be supplemented/replaced with some bus wire apparently) and this set was allegedly sold by Curt to the previous owner.
Is there anything obvious that would make the Bow, Keystone, Skew, and several other controls virtually meaningless?

Check the polarity on the C drive and deflection then check the settings menu. If you can ramp but no corrections the C drive is suspect. Reseat the wave board also. Doug

Plugs are in the wrong way.

Double and triple checked, but did not check that the F drive plugs are in their correct corresponding socket. That is, Red Blue Yellow Brown was verified, but [i]the order[i] of RB, YB was not. i.e. I realized after leaving the owners' home that the PJ might have had its' F drive scan connectors out of order when he received it.
I emailed the owner after leaving him this afternoon to check this, no response yet.

Hello all,
This is my set. Foley is a damn fine fellow for helping me out with this. Even with this limitation he coaxed a damn fine pic out of it, especially in the middle. Made a light year step forward.
I will check the connections on the set tonight. I believe this is a 6100 not a 9100. I have a second parts machine that I can take things from also.
Thanks folks,
Dave

C drive on the Plus should have staggered color connectors where the non Plus will not be so look for that.
The F drive is focus only for each color. Doug

Thanks, Doug...
It's the AR, BR, AG, BG, AB, BB connector placement that I question... Orientation-wise, they are Red-Blue, Yellow-Brown as they should be for ceiling, front... but I drove away from Daves' questioning whether the A, Red connector is on the AR socket, the B, Red connector is on the BR, etc. That is one thing I did not verify in my double- and triple-check.

Assume a novice's understanding.
Are these the connections we are talking about?
If so, I think they appear to be going to the correct tubes. Starting in the back the wires were labeled AR; BR; A? (looked like an "I" but must be a "G"); BG;AB; and BB in a (starting from the back) Red-Blue-Yellow-Brown orientation. It appeared to me that the AR/BR wires went to the Red tube; the A?/BG wires went to green, the AB/BB went to blue. I only traced them to the general vicinity of the respective tubes. I didn't try to further untangle and determine where on the tube a give red, blue, yellow or brown wire attached.
It was also notable that the wires had masking tape on them and a number (1-6) written on it. I assume this was a prior tech's handy work, and I guessed Curt since he reportedly once sold this set.
Should I be tracing the wires on the outside of the board that swings down [deflection board?] or something on the focus board?
Thanks all.
Dave
PS - the label on the back of the set says its a 6100.

Yes they are correct for the PWC-3857B C drive for the Plus. It could be the drive itself. If you have another you might want to swap it and see if it corrects. Doug
Rear RR then GG then BB
