OK so a little update on these VCRs, the PV-1650, I was able to find some replacement idler tires for it, but for some reason it still won't play (it rewinds and fast forwards just fine) but when you hit play it will load the tape against the heads like its supposed to but it won't actually play the tape (move the reel tables) and then it just loads the tape back into the cassette after a few seconds, so I'm not sure what is going on, I checked all of the belts related to the playback mechanism and replaced them all, so I don't know what else could be causing the VCR to not play, and all the motors are fine because they all spin up as they should when powering on the VCR, the service manual for the VCR just lists belts as being the only issue that could cause the VCR to fail to play, but I've alreay replaced all of the belts, unless the belts I used were not the proper length (too long) and weren't supplying the proper tension for the reel tables?
The PV-1750 I was able to get it to Rewind and Fast Forward as well, and the playback idler needs a new tire for it, but I can't seem to find one that is the proper diameter (its around an inch in diameter for the outer diameter and about 7/8" inner diameter), and I had ordered an idler tire assortment from one of the electronics parts suppliers and they didn't have any idler tires of that size in their assortment for some reason, they had one that was the next size up from that one but not that exact size, and that's all that's keeping the PV-1750 from working properly, even the remote was fully functional still when I tested it.
