Ok, I pulled the chassis and did a little investigating tonight

first I returned the original 5K pot to the H width (I had replaced it with a 10K pot which proved to make very little difference).
Next I looked at C912 as Alva had instructed. It is the smaller chicklet style cap next to the flyback. After looking at where the cap was I think what they told me would only be valid if the Narrow/Wide jumper is in the Wide position. In the Narrow position, C912 appears to be taken out of the circuit and in the wide it appears that C912 is placed in Parallel with C902. Since I already have the jumper in the Narrow position, C912 appears not to be used. I forgot to write down the value of C902 but if I recall correctly it is 1333K 13330pf .01333 (?) Anyways, it would appear that if I want to have an effect on the width by replacing a cap, it appears that C902 is the one to replace as it is always in the circuit.
Next I removed the width coil. The slug is solid on both sides and is as long as the coils windings. I proceeded to push the slug out from the bottom so it was sticking out of the top and gave me something to grab onto in order to adjust it. It is not meant to turn but rather just slide up and down. I replaced the width coil and installed the chassis. On powering it on I was greeted with a narrower screen but still not quite enough. I turned off the monitor and adjusted the slug up pulling it more out of the coil. Doing this several times showed me that there was a sweet spot for the slug before it started getting wide again. I thought it was strange since I was pulling it out that it would start widening again. I thought that if it was removed completely that it would be at it's narrowest. I never removed it all the way but had quite a bit sticking up the top.
So where I am at now is that it's almost there. In the screenshot below, if you look at the bottom you can now see Edit 00 on the left and Credit 0 on the right. Tomorrow I plan on getting the numbers off of C902 and getting a smaller cap. Any suggestions on how much smaller? 10%, 20%??
Thanks for reading through this and for any help or suggestions you can give. I am hoping by going through all this it will help others with the same chassis be able to be able to get around width problems.
