The heating of right speaker side and distortion is related to the Analog board, which consists of the AMP I.Cs. If you connect it to an external AMP via headphone, all works fine. Solution is to re-soldier the AMP I.c (2 of them) and resoldier relay and all the minor components around the AMP I.c.

Yamaha PSR S700 right side speaker overheating
by: Anonymous

Hi Justin,
I have had my PSR S700 for three years now and my keyboard has the same problem. Overheating on the right side speaker and rhythm distortion which has nothing whatsoever to do with high volume. Since I have a PA system with speakers, I drop the volume to very low level and let the PA do the work. My PSR S700's fault occured 2 weeks after purchase, I returned keyboard with recorded tape of the distortion and the supplier told me I was wasting my time and that Yamaha would not repair or replace speaker! Is this true Yamaha?. In every other way I am pleased with keyboards performance, and considering updating to Terios

Heating of Yamaha PSR 700 keyboard
by: Masoud

Hi Justin,
I have a Yamaha PSR-700 OR and like you have the same overheating problem on the right hand speaker. I have solved the problem by adding external speakers to the headphone socket at the front of my keyboard. As the result no overheating takes place. In my opinion the overheating problem is a fault and if you are not carefull it might damage the electronic components of your key board. External speakers of a PC computer would be sufficient to solve your problem. If you are going to play in a large room or a hall you could still connect the strong amplifier speakers to the connections on the back of the keyboard. Use the speakers connected to the headphone socket at the front as Monitors so that you can hear the sounds.
Good luck
From Masoud
