yamaha psr 170

by maria mcglynn

Hi there. Bought a yamaha prs170 about 8 years ago. Never really used it. Decided to get it out but could not find adaptor. Went to smyths and bought one. Plugged it in and i can hear that there is power going into it, but nothing is happening....Adaptor is right wattage etc. Obviously cannot find instructions either.......

PSR 170 - Nothing Happening
by: Alfred

Dear Maria: Buy a spray can of Electronic Contact Cleaner and try a possible quick fix by MODESTLY spraying Electronic Contact Cleaner into Jack (Entry point of Adaptor on keyboard)and working the Adaptor Plug in and out of that point. You say you can "hear power going in". If the sound is that of a note produced when pressing a key, the keyboard may not be receiving the full Adaptor voltage output due to dirt/oxidation of the Jack. Humidity during storage may have caused the problem. Remember spray sparingly.
Good luck.

PSR 170 - Nothing Happening
by: Alfred

Dear Maria: Further to my post of 8/13, I have reviewed my old (forgotten)notes and you should be advised that after a long spell of disuse there could be problems in the internal power supply of your keyboard. This supply usually includes one or more Electrolytic Capacitors which tend to deteriorate with a hiatus of any length. If you are not qualified to repair the unit, find a reliable technician to do the job. Good luck.

Psr-170

by Kaitlin

I just got a Yamaha Psr-170 keyboard, but it hasn't been working. I have a brand new adapter for it. I was wondering if there are other cords I need for it besides just the adapter?

Recently-acxquired PSR 170
by: Alfred

Dear Kaitlin: Your keyboard is "relatively new", and depending on how it was stored/maintained in the past, may have a simple-to-fix problem with its Jack (Connector part on keryboard where the Adaptor is plugged). Buy a can of Electronic Contact Cleaner Spray, and squirt a MODEST amount into the Jack. Work the Adaptor plug in and out at that point. It may work. Good luck.
