Where Can I Find Replacement Roland Juno G Parts?!

I recently bought a used roland juno g off of ebay, and i believe the contrast knob/pot (I'm not exactly sure what its called) is broken. I want to solder the replacement piece on my own, (because i have experience and can't afford bringing it into a certified repair shop) but i have had absolutely no luck finding it even after looking on sites that specifically sell general electronic bits 'n pieces. I took apart the keyboard, and there is a number on the contrast knob/pot which reads "OC203B".
I would really appreciate any possible solutions as i need this to be working for my gig next weekend!

thanks

yes, im in the same predicament. i bought a used juno g and the main volume knob kind of crackles when u turn it, it looses output in the right side.
i want to know if its possible to repair it. or if i can buy a new volume pot and put it in. i dont know about soldering but i know people who can, any help on how to repair or where to get parts.

I have a Juno-G but no problems as of yet......Did you try contacting Roland for the part, especially since you have the part number..? Good luck...

I know this is an old post, but anyone who has a problem with the volume pot may be better off just buying that whole Panel A board. I'm not even sure if you can just but the volume pot or any individual part on the board like that. It was actually cheaper than I expected... $59.50 for the Panel A. Has all the tact switches, d-beam and volume pot. I would just have to transfer the buttons over to the new board.

For those who don't know, when you open up the JUNO G, it's broken down into 4 or 5 boards/panels.
The Main Board, (where the RAM, SRX Slot, blah blah blah is located), the Jack board, (or something like that...all the I/O and midi and things), then Panel A, (mode and volume and stuff), Panel B, (screen and function/category buttons), and Panel C, (faders and all the rest of that stuff lol)...

My question is how do I check the status of this order without calling them for info? I was told this part was back ordered so it may very well be between 4 and 6 weeks before I get to use my JUNO G and actually hear what I'm playing lol.

Also, sorry if this is a bit thrown together, I'm trying to eat, feed my son, type and straighten up a bit...oh look, I think he made a stinky...GEE LUCKY ME!!!

I had a Juno G in for repair today with a broken volume pot.
A quick call to Roland here in the UK and the very helpful chap at the other end has one shipping to me, cost around 5 UK pounds per pot.

Looks like there's no need to replace the whole board after all!

Cheers

Oye, I am having the same issue with my Juno-G and it is not even 5 years old but past it's warrenty.

If you just buy the pot is it harder to replace then the whole curcuit board A?

Omg thanks, so i can just buy a new volume POT? so freaking cool, do i have to be under warranty to order it from roland? this means i can just buy that part and install it myself? When and if i can even do that is my problem i guess.

Old thread, I know, but I need to know if anyone happens to have a pic of the OC203B pot, or more info such as the manufacturer name etc. Thanks!
