Attempting first project - Some questions if I may

[Electronic M]

Whether to swap connector or wire is a judgement call for you to make. If the original wire is damaged or significantly deteriorated it may be best to replace it...if all it needs is a clean you may want to keep it.

It typically solders to the bottom of the HV rect socket... how much of a job it is to swap the whole wire varies from chassis to chassis. Gotta look yours over and assess it to make a decision. Be aware that the solder joint under the HV socket needs to be smooth...any sharp points will encourage arcing and or Corona.

Changing the connector: typically you grab the fingers with needle nose pliers and pull the fingers and lead out from the center of the suction cup and unsolder the fingers from the wire then yank the cup off the wire...the old cup will be crusty and difficult. Most newer cups you find will be the same process ( only you have to do it twice forward and once in reverse for a swap), but there are oddballs out there. When transplanting note how the new part was put on and match the workmanship.

Thanks for the answer. I have been busy but am getting around to fixing my TV's. I am back to the '71 as I study more about the '65 HV cup swap out.

Anyway, this '71 is driving me nuts! I just replaced the fuse and a bunch of other stuff Sam's recommended when there is no raster, no sound.

Now nothing has ever been wrong with this set, then one day the volume and on/off knob fell off and ever since then all hell has broken loose! I had to glue it back in but I thought nothing of this at the time but ever since a couple of days after I did that, I get no picture or sound when turning on this set. But today, I got mad and flicked the on knob with my finger and it turned on. Then I tapped the other side (see pictures, I don't know terminology) and it turned on again.

Also, please see video. What the hell is that? If I rock it, it turns on and off while it is powered on? If I set the set upright it won't power on.

Thoughts?

Can we revisit this? I tried everything. Can someone give me more information on either the contacts/switches being bad and how to troubleshoot that, or how to wire it to always be on (and turn it on/off via plugging it in or out). I tried everything at my disposal and cannot lick this problem.

Thanks.

Just solder a jumper (wire) across the switch to make it be 'on' permanently.

But from the video, it looks like the break may be in the cord or the safety interlock.
