JVC TT-101 Won't Stop

Just note that likely you need a set of probes for the suggested oscilloscope.

Safesphere, Wish I could help, but you've already gone further than I in parsing out that circuit. Early on in the repair of my unit, I gave it to a very competent pro who found no issues with the ICs or the discrete transistors, after he replaced all the electrolytic capacitors. I own a 'scope but have never applied it to repairing the TT101, because the problem is very intermittent and elusive in the first place.

If you are not already seeking help elsewhere,you may find a teck hanging out on Audiokarma or diyaudio.

Safesphere, I am bumping your thread. I did some re-wiring on my TT101 over the weekend, also found a bad electrolytic capacitor on one of the PCBs that are mounted under the top cover. (This was the only original lytic that we failed to replace on the first go-around, and it's the only lytic to be found under the top cover.) In the process of "improving" the wiring integrity, my other goal, I screwed up something. I need to ask you about the order of the wires in one of the connectors on that board. I hard-soldered them to the male prongs, because the connector was very loose. Now I fear I may have gotten the order incorrect. I will post the parts number for that connector, and maybe you can check yours for a reference. (The wiring is color-coded, as you know.) I turned what was once a rare intermittent problem into a consistent problem. Aaarrrggghhh!!!

Safesphere and anyone else with a dismantled TT101,
The connector in question is nearest to IC810 on the Crystal PC Board Assembly, TDC-7B. This PCB is located under the top circular piece that surrounds the platter. TDC-7B is depicted on page 31 of the owner's manual. The order of the four wires going into this connector, as I have it, is: brown, (space), orange, yellow, green. Please check, if you can do it without much trouble.

Upon second look, I think I've got it correct, but I am grasping at straws, trying to figure out what I did that could have worsened my problem. I cannot find anything else that could be causing my TT101 to upchuck. Thanks.
