Yamaha YPT-410 When playing the keyboard, the sound cuts out when playing multiple keys, and then begins again only to cut out again. Does not matter which keys. I have done a factory reset and it did not help. It is almost as the sound level goes up and reaches a point the sound stops.

Hi, If by "re" not working you mean note D then try the following.
Keyboard off, hold down top C key while turning on. This factory resets. Does D key now work - if not. Has it ever worked - if not then it could possibly be the ribbon connector between the keyboard and the motherboard. If one of the cables gets bent then this would stop all notes associated with that connection to stop working. This will only have occured if the keyboard has never played these notes or if it has been taken apart.

You could also try the self test mode : Keyboard off, hold C#,F, G# in the 2nd octave up whilst turning on, cycle through tests to sound if it plays all the notes one at a time then the sound chip is ok and it points to keyboard switching. If test mode does not come up in 2nd octave try 3rd octave ( cant remember which one it is from memory )

Let me know how you get on.

The problem is in the inside of ypt310,nothing to do from outside.
Is it after the unit is turned off, and then revived, this conditions happen again?
If the unit still can play for a minute/moment, the damage is usually located on the regulator. There may be a capacitor/resistor/ic damaged by heat. When there is not hot, the regulator is working normally, and the unit was normal. But after a while the heat turned up (at component parts), the regulator becomes abnormal / unstable, and the unit is turns off.
There may also be damage in the other section, which causes the regulator gets hot. If you are not experienced in electronics repair, then leave it to the experts.
Try also, check the wiring-connection from regulator to another board (usually using the socket, it may loose its socket)

carefully remove the cover of your ypt-320 and also remove the sticky key to check the rubber pad under it .try replacing it.

That's the thing with today's electronic and why warranty length is so important. Where did you buy your keyboard? It's strange that they won't fix it if it's still under warranty. My Casio CTK-2100 came with 1 year free service and they fix one key that stopped function in few days. I'm pretty sure Yamaha has the same warranty length. You sometimes have to be very persistent with them though...

Try to search for XG midisongs and karaoke files (song extentions should be .mid and .kar) on the Internet. There are lots of free songs out there!

We have a Yamaha keyboard YPT-330 note E and F sharp not working why?

Press the FUNCTION button till "Local Control" appears and then select it "On".

It appears this may take quite a bunch of presses to get down to the Local Control option.

Refer to your manual around pages 56 and 57 to see the list you step through. Local Control is about 2/3 the way down page 57.

Refer to 59 for the simple instruction toe set Local Control on or off.

This is likely a dirty contact. MANY of these keys use a conductive rubber "pill" that is pressed across a set of circuit traces on a circuit board.

Dis-assemble and clean both the "pills" and the circuit traces with 99% isoprophyl alcohol.

The pills are often under silicone rubber domes that also serve to spring back the keys.

If the unit uses a wall transformer, make sure you have the right unit.

The Yamaha correct ones are branded Yamaha. Use of the wrong one can damage keybooard or be inoperative.

The PT300 did not come up as a valid keyboard. Suspect the number is either YPT-300 or a P-300..
