another zenith combo

[DaveWM]

I have been fighting with some minor pic problems, tends to bloom a bit go out of focus on some scenes. check the HV again, 26kv with pic, but jumps around a lot with brightness (beam currrent on crt). when set to the setup mode the HV is 27kv and will not go lower (that is with it turned all the way down).

I have been down this road before, on my last zenith with the pulse type regulator (6HS5). That one required a new VDR and a factory mod to the HV control pot to get under control.

also while watching I noticed the reds start to fade to pink and get splothcy.

the darn purity ring assy is very loose, some how I must have moved it. I found it when I checked the setup (after checking the crt). Oh well at least I am getting a bit faster at finding the problem.
