Topic: Any internal pics of the Yamaha PSR-SX600?

[svpworld]

I am curious (as an electronics person) to know a bit more what's inside the PSR-SX600. Obviously just got mine so not planning to open it up just yet, but any schematics, photos, ideas of what CPU and chips Yamaha use in this model?

hi Simon,
SX600 is not that long on market and so there aren't any sources available yet. Here's one (bad quality) video where you can get rough impression of how it looks inside.
If at all, such info starts to appear after many years... For example, PSR-SX700/900 are on market since 2019 and I still couldn't find "Service Manual" anywhere.

I would imagine since it is the same chassis as the S670, just the main systemboard would be the change.

So today I came across a copy of the service manual for the SX700 and SX900.  Looking at the schematics, both SX700 and SX900 use an identical set up comprises the SWP70 tone generator chip and AM4376 1GHz clocked CPU. These are also the same CPU and tone generator used in the Yamaha Genos (although I think the Genos has 2 x SWP70s). 
Assuming the SX600 has the same chips, it's not surprising that the higher price of the SX700 and SX900 is mainly down to software, plus a few ancillary chips for the vocal harmoniser, USB hub and upgraded audio amps.  Of course I might be completely wrong and the SX600 has a completely different set up...  let's wait and see!

I should imagine the touchscreen would account for a fair bit of that price increase

These "home movie" videos drive me bonkers! It's as if my grandfather used an 8mm film camera to take pictures of us kids at the playground. 

Please, if someone goes to the trouble of opening a keyboard, please take close-up still pictures of the main electronics board. We need to be able to read the markings on the individual components. Then we can answer questions like Simon's. 

All the best -- pj
