yeah unfortunately even after replacing almost 2 dozen failed electrolytics out of this VCR between the Audio, Servo, Slow/Still and Skew boards the VCR is still not wanting to play SP recorded tapes properly.

Plus the VCR has developed a new issue, where the video coming from the VCR when playing tape is just a garbled mess of white noise with the video's audio coming through clearly in the background (LP Mode specifically does this), where it will start off playing the tape at the wrong speed but then after about 2 seconds the screen goes blank and then starts playing at the correct speed, but the video is nothing but a garbled mess of white noise.

The weird thing is that after I had initially repaired the LP Playback speed issue, the VCR played the tape perfectly right away (there wasn't any delay in the speed selection like there is now) and the video playback was crystal clear (no garbled video output like its doing now.)

The weird thing is that the video started acting up when I went over the Audio and Servo Boards a second time and replaced the rest of the bad caps I missed the first time I went over those boards.

That was when I then decided to go over the Skew Board and the Slow/Still boards as well to see if those would make any difference with the playback speed detection issue, and that's when I figured out that unplugging and plugging back in all of the plugs on the Audio board for some reason corrected the video issue initially.

But then when I recapped the Slow/Still Board and the Skew Board and plugged those back in and tested the VCR that's when the garbled video issue showed up and unplugging and plugging back in the cables from the Audio Board didn't fix the problem this time around.

That's why I was saying that replacing the capacitors on some of the boards in this VCR was somehow making the tape playback issues worse and not better, (because while I was able to fix the LP mode playback issue, the SP mode playback issue was still not fixed and the video playback quality went from crystal clear, to nothing discernable in no time flat.)

And I'm not sure what's going on with this VCR and why all of the sudden when I replaced about 2 dozen nearly dead leaky capacitors that the VCR is no closer to being repaired than it was when I first discovered it had a playback speed issue.
