Finally mustered up the patience and time to finally pull the chassis out of the Zenith. I more thoroughly cleaned it up as well as the inside cabinet. I used deoxit on all the pots. I am going to replace all the electrolytic capacitors, paper in oil caps, wax papers, wax paper safety caps ect. I even found at least one bumble bee cap and a sprague black beauty. I ordered the replacement capacitors needed from Digi key and am waiting on those.

Also checked on the bulb near the tuner and surprised to find that it is not burnt. I also plan on testing all the diodes in circuit using a multimeter. Will check thermister, flyback, and other transformers.

Oh and I somehow managed to find and buy a NOS Thordarson Vertical Output transformer for this tv. So if that transformer is bad or does go bad I will be ready for that.

I already clipped out two wax paper caps to examine more closely and made note of their location. Also will be needing to get a replacement inductor or two for the convergence board that is screwed on the top part of the wood cabinet as the plastic is literally turning to dust and falling apart.

I am planning on doing a full restoration of this tv to look like new in performance. I will even eventually work on restoring this wood cabinet. Cataracts look minimal on the screen. Speaker fabric grill needs replaced as it is all chewed up.

Two wires got pulled off and will need to be resoldered but that is no big deal.

Taking this apart today gave me quite the workout. lol
