PSR-S950 orange lights (instead of green...)

My PSR-S950's INTRO I, II, III and main A,B,C are lighting in the color Orange, instead of Green.
See picture (I can't attach a video ATM).

I'm using a genuine Yamaha's AC, and changed my AC outlet to rule out electrical problem.

Have anyone of you have seen this before?
Any ideas?

Thanks!

Try doing a factory reset...Pg 31 in the Owner's Manual.

You can also reset a specified setting to the factory default value.

Call up the operation display: [FUNCTION]  [I] UTILITY  TAB [E][F] SYSTEM RESET.

For details, refer to the Reference Manual.

Hopefully, this will fix your problem.

I don't believe a factory reset will change this at all. It appears that the voltage to those lights is lower than it should be, which may, or may not be a power supply problem. LEDs can do some whacky things when the voltage requirements are not absolutely on the money, and it only takes one component in the power supply or one of the boards to cause this. This may be a send it back to the factor repair center job.

Good Luck,

Gary

Yes probably a send back... Often times there is a network of resistors connected to those lights, one of them might be broken..

European voltage changes could cause problems without the proper converters..

Donny, the OP is in Israel, the power there is 220-240-volts AC. The PA300 power supply that came with the keyboard is a universal power supply, and it runs on both 120 or 240 volts AC, so there shouldn't be a problem.

Gary good to know ....is it a used KB purchase?....maybe previous owner error?

This is a newly (less than a year) purchaed unit.
I still got it under warranty.

I will contact my local dealer.

I never had this kind of problem with any previous Yamaha keyboard I've owned (and all were newly purchased, all with genuine Yamaha power supplies).

Thanks everyone, I'll keep you updated.

More than likely its the voltage, cycles of 50 that the lights dont like . Over here in the US we have 60 cycles.

Went today to the local dealership.
The technician was very surprised with this kind of issue, said he never heard about it.

Anyway, couple of hours later he resolved the problem, something with the LEDs (not an electrical problem, or a faulty board, just one f*cked up LED that affected the others).

Everything is fixed now.

Glad you were able to resolve the problem.
