No.
By this I assume you mean the fact that your termination resistors all ground to the same wire? No. That shouldn't be a problem.
Also, I doubt it has anything to do with the issue, but what is the third wire on your blanking switch?
No.

Have you removed R358/R359/R360 (if present)?

Pulled power from the bottom side of the micon pin 46 because of an RF Shield. C375 was already empty and unbridged on my model so I couldnt remove that to improve brightness. If you want I can get a pic of the bottom and top side if itll help
the only thing I can think of is to cut the Pb Resistor in half to increase brightness but that might only fix my blue issue. I could try to sync to the front Svideo port but not sure if that change a damn thing.
Third wire is ground, I assumed i should ground it just in case of internal short
Added the caps myselfBard_the_Bowman wrote: ↑Tue May 14, 2024 12:09 am Also did you add the caps in pic no. 4 or were those already present? The reason I ask is that I just want to double check they actually are 0.01 uf and not some wildly different capacitance. I looked up the service manual for your unit and I can't find those caps, so I'm not sure what the default value would be.
no jumpers were removed just the resistorsBard_the_Bowman wrote: ↑Tue May 14, 2024 12:09 am And to expand on my last question, if C360/361/362 were NOT populated from the factory (which I'm guessing MIGHT be the case since I can find no reference to them in your service manual), were there jumpers at JR351 and JR352?
I doubt it's the jumpers cause if it had them, and you hadn't removed them, the signals would be shorted and you'd have a profoundly messed up image I would think. And I also don't see them listed in your service manual. But it MIGHT be worth double checking if all else fails. They're little surface-mount chips on the underside of the board.Ramzelle wrote: ↑Tue May 14, 2024 12:59 amAdded the caps myselfBard_the_Bowman wrote: ↑Tue May 14, 2024 12:09 am Also did you add the caps in pic no. 4 or were those already present?

Image shows all the work that I did

It sounds like you may have some components left in circuit. Did you disconnect everything from the PIP circuit?Ramzelle wrote: ↑Mon May 13, 2024 5:38 am So I did so more trouble shooting on my AA-2D tonight. I found that when I switched back to composite my colors and brightness came back and the Tube wasn't as worn as I thought it was. Re-Tuning the Screen for composite I found that the image was fairly crisp and not blurry and I believe a lot of my issues have been from trying to compensate for the loss of color and brightness in my Component mod. It sound like my version of the AA-2D is slightly different than Bowmans since I did not have a cap in the same spot as him but overall they should be fairly similar.
I am trying to figure what I should look for to try and trouble shoot all this brightness and color loss. would too many ohms on a resistor, or a diode or some cap be pulling voltage and causing my issues. I am obviously not formally trained in small electronics but if I have something to go on I could try to investigate further and maybe cut an unimportant trace or something along those lines.
I believe so, I removed the resistors and the pip circuit board has been removed. according to the research I did that was everything that needed to be removed ill pull the board and take some photos. maybe I missed something that is specific to this model. I tried to look at the service manual and previously posted a picture of the svideo circuit but personally couldn't see if there was anything that I forgot in circuit.
