Question
RoweJukebox
Hi all. I have spent far too much time researching and trying to fix to no avail.
My Rowe R-86 just cycles the transfer arm up and down and drops the record, picks it back, etc..
It is commonly said this means the custom chip is not responding.
Today I received the cdadapter.com modern replacement that replaces this unavailable chip.
It put it together and installed it, both correctly, and when I turn it on it does the same exact thing with a quick flash of the "activity" led on the new board. It's great that it offers "error troubleshooting" but not so great when it doesn't boot right to even get to that. :( My symptoms are the EXACT same as when I had the old chip in there. I get "100" showing on the selection display, with the "selection playing" light blinking. Nothing is turning on or locking on besides the transfer motor (which means the turntable is not spinning either). I have tested all the parts manually and they work great and as mentioned below I played with it all manually and got my fill of playing records by hand (removing the chip let me lock everything on) so everything works great in theory but is not being "requested" to be turned on.
It already had a socket installed so I am going to replace the socket with a brand new one (the one that came with it was kind of bad so I'm ordering one!) and see if that fixes anything but other than that I need help because it is clearly something much deeper on these boards.
I am suspecting perhaps a RAM chip or something of the sort. Lots of them are already socketed, which is great, but also tells me somebody else clearly already spent a lot of time trying to fix it and did not so that is a little discouraging, lol.
Please do not refer me to any "pay to repair" services as I am capable and just looking to know what to fix next.
Also, when I take the custom chip out and turn everything on, everything locks on. (Which is great for playing around with it by hand in the meantime if you disconnect the transfer motor!) Is this normal operation when the chip is not inserted or does it mean there is another problem that would cause something like that? Nonetheless, this quirk let me know all the wiring is good because it was then forcing them on just fine.
I have already reflowed all headers on the CPU board, mech control board, and the pricing board looks absolutely immaculate underneath so I left that alone and even resoldered some there too I think.
Thanks for your help.
