I had pretty intense arcing out from the CRT connector on a similar Motorola when I first started messing with TV over 40 years ago. Optimal time of year for that nonsense! I had to clean the CRT and then the connector suction cup rubber with silicone to get rid of all the tracking. The HV rectifier was a 3A3, like what a color TV used, so I know the HV was higher than normal BW sets.
What is the chassis number? Mine was CDTS581YA totally all-gray metal 19" cabinet, like my avatar.

I figured the blue glow was nothing, the power tubes in my home stereo have a blue glow, but I'm kinda a noob to TVs......
I fired her up tonight and found some arcing in the HV rectifier socket, though it looked like it was happening inside the tube. Time to pull it out for a good clean! Quote:

So this TV has been playing well, I replaced the HV lead, cleaned the cage, replaced the tubes in the tuner. I also cleaned the "noise gate" pot, it was scratchy and made the picture go wavy/buzzy intermittently.
only quirk I have now is some buzz in the audio which can sometimes be minimized with adjustment of the fine tuning. Perhaps I have a dirty tuner? or could it be alignment related? |
