#351899 - 09/30/12 07:00 PM A serious pot problem
Beakybird Senior Member Registered: 01/27/01 Posts: 2227	I recently had each of my two PSR-S910's repaired because I was having to press the EXIT buttons harder and harder to get them to work. One of the keyboards had to have the BREAK button replaced as well. It cost $200 to fix both keyboards. I'm kicking myself because one of my keyboards has been having trouble with a scratchy sound when I turn the volume pot, and I forgot to mention it to my technician. I have tried to blow compressed air (with a can, not my nose), but it doesn't help. I probably need to remove the pot - or I don't know. Is there any way - short of opening up the keyboard - to fix this? Edited by Beakybird (09/30/12 07:01 PM)

tony mads usa Senior Member Registered: 01/16/02 Posts: 14376 Loc: East Greenwich RI USA	beakybird ... fortunately, I've never experienced the problem so unfortunately, I can't help ... 124's suggestion sounds like a good one ... have you tried this: http://www.amazon.com/CRC-Electrical-Contact-Cleaner-Aerosol/dp/B003NTQCA2 customer reviews look good ... BTW ...sorry to have continued this thread down the wrong path ... don't want it to get to the point that you have to 'weed' out the helpful suggestions ...

My guitars and amps develop the same problem, and this stuff always works. Usually, it's lack of use that causes the problem. Russ

zuki Senior Member Registered: 09/20/02 Posts: 4723	I had such a bad problem with my 910 and 3000 before that. Yamaha simply doesn't make those buttons hold up to constant use. I like the 950 looks, but the pots.........yuk _________________________ Live: Korg PA4X/EV Everse 8s/Senn 935/K&M stand Studio: Korg PA4X/Yamaha DGX670/Nord 6D73/Boss BR900CD/Tascam DP24SD/MTM Iloud/Sony C80/AGK 214/ATEM Mini Pro switcher/K&M stand

travlin'easy Senior Member Registered: 12/08/02 Posts: 15576 Loc: Forest Hill, MD USA	DO NOT USE CONTACT CLEANER! First, the pot is hermetically sealed, therefore contact cleaner will not work. Next, Contact cleaner can adversely affect other components on the printed circuit board, some of which could produce some really bad results. The best advice I have is to replace the pot. If you cannot do this one yourself, have it done by someone that can. Jim, I've had a pair of 3000s since they first came out, which I believe was early 2006. Never, in all those years, with thousands of jobs, had a single button or potentiometer failure. I did, however, have a 1/4-inch foot-pedal jack and a USB Host connection go bad on me a couple years ago. Good Luck, Gary _________________________ PSR-S950, TC Helicon Harmony-M, Digitech VR, Samson Q7, Sennheiser E855, Custom Console, and lots of other silly stuff!
