 |
|
Hi,
this is a randomly occurring problem. When I push the power on button, in the most cases nothing happens. But sometimes the piano turns on and works perfectly. I can turn it off. Again trying to turn on, nothing happens. Sometimes when it works for a while I can't turn it off.
Pretty annoying. Checked the power supply with a multimeter and I measured 12V. |

Maybe could anyone help me out with schematics?
Thanks in advance. |

| So it's interesting: when the problem occurs - can't turn on the piano - I measured 0,5V on the standby microswitch. When it works - I can turn it on - I measured 3,2-3,5V. |
