Here is a video of the issue I would advise muting the sound since the washing machine was on and very loud. https://www.youtube.com/watch?v=Mj-cJ4nwUeM

Looks like the washing machine is modulating the video, interference of the low frequency type. The interfence will over load the agc.

You are right Ed. Once I unplugged the washing machine I did notice that the horizontal was a lot easier to lock but the vertical is still an issue. Anyone know what else could be wrong here?

I would guess, since both horiz and vertical lack sync, there's something wrong with the Sync Separator circuit.
I would start by looking at everything from Coil L16 to pin 1 of V12.
Also everything else involved with that tube, particularly resistors.

The thing is that I think I replaced all resistors in the sync sep circuit. But I will check voltages tomorrow.

If you replaced all the C3(a-c) and C4(a-c) electrolytic caps, then try spraying the vertical hold control to see if it slows or stops the vertical roll. It still looks like you are not getting the proper sync pulse at C44. Out of spec resistors in the vertical circuit will cause rolling issues also.
Ed

Should I replace C44 the 4700pf cap since the vertical circuitry has had almost all of its resistors replaced?

Yes?

If your horizontal Sync is staying locked then replacing C44 may help. A better video may help us diagnose better. As many of the other members have mentioned it looks like AGC/ SYNC troubles. Do you have Scope to check the wave forms? Your AGC may even be overloading which can cause sync troubles.

Replacing c44 did help out with the horizontal hold but it still has a bit of jitter on the horizontal. The vertical still wont lock but I can get it to almost stop rolling. I am really starting to think this is not agc but a sync issue. I would hook up the wo-33a now but my bench is a mess.

OK agc amp tube seems to be way off with voltages. Correct voltages are pin1 (-6.8vdc)
pin5 (-140vdc)
pin6 (+115vdc)
My readings.
pin1 -36vdc
pin5 -2.17vdc
pin6 162vdc

Yeah I think we have an agc issue here. Any suggestions on where to start with the agc? I also must mention that I have no sound whatsoever. Speaker isnt even being driven but the speaker is good. I am more concerned on the agc issue now however.

Anyone?

Did you see the note under the Sams voltage chart that mentions the voltages on pins 1,5,6,7 are referenced from pin 7 of the AGC tube? EdKozk2 mentioned it in an earlier post. Earlier you mentioned you have -4.17v on the AGC line, which is really close to the specified -5v. Being that close I can't see how the AGC could not be working, there's no other place that -4.17 volts could be coming from. If you want to play with the AGC voltage, pull the AGC tube and substitute it with a -5v power supply voltage.

Yes I used pin 7 as the ground for the measurements. I do see a 47k isolating resistor coming off of Grid 1 on the agc tube that I did not replace. Should I replace that one? Or is it not critical?

As long as the 47k is within 10 percent it should be fine.

There's some very good reading here on page 5, on how this pulsed ACG circuit works, along with trouble shooting tips. References the schematic on page 14.

Are you getting any change in ACG voltage when you vary the input signal strength, as well as the contrast control?

I never realized this chassis used such a complex AGC circuit. Not the easiest circuit to understand.
