I can confirm the HV cage is indeed on the left side of the tv when viewed from the back.

I have identified the primary point of failure in the tv as an impregnated wax paper cap in the power supply circuit. The capacitor failed open and is located right under the line filter and next to where the line power comes in. I noticed the tv has another with an identical value of .15mf and 400V on the top of the chassis. I will also replace that one as well, as the reliability of wax paper caps is notorious for not being good. Will check over the fuses and the circuit breaker once more as well.

Honestly should have realized this sooner, I did see it but did not realize it was a wax paper cap due to the plastic shell on it.

On the plus side ALL the electrolytics in the tv including the can caps all tested GOOD according to the capacitor wizard, which was a big surprise to me.
