TV repair books

[DaveWM]

I have a fair understanding of electronic circuits, I am looking for some books that help with diagnosis of tube type (vs solid state) TV problems.

What I am hoping to find is sort of like this:

Dark bars on screen check filter caps along with pictures.

One of the problems I have been chasing is vertical snaking. Been a real pita trying to figure it out. It seems like a decoupling issue with the vertical osc/amp mixing with the AC ripple in the power supply. But I checked all the decoupling filter caps. Checked HK shorts. Checked just about every darn part on the sweep board.

I did have some sucess by running the sweep board on pure DC for the filaments, but that is not a perm fix. I tried new tubes, cleaning the board etc...

The one thing I have not tried is to clean the grounding points of the PCB to the chassis (a 63 magnaox)

anyway I figured I need to expand my troubleshooting skills and was hoping there were some books out there that may help.






I find the service manuals helpful but I dont have ready access to them.

I found on book TV repair for beginners but it focused on solid state and color.

any suggestions please?
