Hi everyone,
[UPDATE March 20th 2016: Yamaha have released a v1.05 firmware update that appears to fix the issue for many users but please keep reporting to Yamaha and this thread if it hasn't worked for you. Thanks, Paul.]
I've been having a problem with a couple of PSR s970's and their [A] to [J] keys registering either not at all or double pressing. I'm wondering if other people have the same problem?
Here's a a link to three videos showing tests that demonstrate faulty right screen buttons, normal left screen buttons and another test showing faulty right screen buttons:

-----------
The fault appears as if the keyboard behaves erratically, randomly exits screens (most noticeable when selecting voices), on/off buttons changing from on to off to on again in one press (e.g. in the organ flute screen, the vocal harmony screen, song setting screen), button presses not being recognised, save and information requesters cancelling themselves, saves overwriting without confirmation, or other intermittent random events occurring when pressing the [A] to [J] screen buttons.
The actual fault is the [A] to [J] buttons intermittently registering as a double press instead of a single press or not registering at all. It can affect the buttons on one or both sides of the screen. The keyboards I had were part of the November batch delivered to the UK and were both tested running firmware 1.03 and 1.04.
TEST YOUR KEYBOARD
--------------------------
To see if your keyboard is affected, follow these procedures:
TEST 1 (demonstrates fault on both sides)
--------
1. Disconnect all external devices such as pedals, WIFI dongles, USB sticks and MIDI cables.
2. Power on the keyboard.
3. From the main screen, press the [Piano] voice category button to open the voice selection screen.
4. Single press button [A] then [B ] then [C] then [D] then [E]. Repeat 12 times (60 key presses). The timing between button presses doesn’t matter but ensure they are all single button presses.
RESULT: If your keyboard is OK, the selection will move with the key press. If your left hand screen buttons are faulty, the keyboard will exit the voice selection screen back to the main screen during the test.
5. If your keyboard went back to the main screen, return to the voice selection screen.
6. Single press button [F] then [G] then [H] then [I ] then [J]. Repeat 12 times (60 key presses). The timing between button presses doesn’t matter but ensure they are all single button presses.
RESULT: If your keyboard is OK, the selection will move with the key press. If your right hand screen buttons are faulty, the keyboard will exit the voice selection screen back to the main screen during the test.
TEST 2 (only demonstrates fault on the right hand side buttons)
--------
- See video. From the main screen single press [G], [H], [G], [F] and keep repeating the cycle for about 60 key presses. If the voice selection screen appears, you have faulty right hand buttons.
Please let Yamaha Technical Support know if you have this problem. It would be useful to compile a list of people with the issue in this thread as well as which keyboard is affected (s970 or s770), the month of purchase (batch if known) and which country the keyboard was purchased and I'll point Yamaha to this thread.
I will update as soon as I get any more information.
Many thanks for any feedback.
Paul.
