Hi
the first thing to try is a factory reset
hold down the highest note while you turn the keyboard on.
once it has started up try again.
if there is only a faint sound when played it could be that the main amplifier has failed or that the speakers have become unplugged from the power board.
does it work on headphones correctly, if it does it points to an amplifier problem.
report back if the reset works

Not sure about your particular keyboard, but on the Yamaha Tyros the style will NOT start rhythm until you select start AND hit a chord.
The style doesn't know what chord to start with until you trigger it.
SOMETIMES the style has to be moved to a user space...
One has to read and then DECYPHIER how to work these synths... Spend a little time with the user manual, as hard as it is to understand.

Yep, a key contact has got contaminated... You have to disassemble the unit to expose the keys.
You have to remove the offending key which is OFTEN tied to a bunch of keys. Under the keys you will find strips of silicon rubber with little domes sticking up. Under the domes are two contacts, either two black conductive rubber or sometimes a ring with a pill in the middle. These contact circuit traces with a black coating on the board under the keys. Clean the pills AND the circuit traces GENTLY with ONLY 99% isoprophyl alcohol. Reassemble the keys and the unit.
Be very careful handling, especially the ribbon cables between teh upper and lower halves of the unit.
Note there are TWO contacts per key which one closes before the other and that is how the key velocity is measured by the processor.
