Yamaha moxf8 keys are not producing sound

[Hilton]

Hi,
Kindly help my Yamaha moxf8 keys are not working I cleaned it up but still most keys are not working am suspecting the snake cable I have attached

Firstly that's a ribbon cable, not a snake. A snake is a bundle of cables.

Secondly, if you spend $10 on an ohmmeter you could test the thing and know for sure.

How in the hell are wee supposed to test a photograph of a cable?

Thanks Gary.
It was tested earlier to day.
Kindly advice on where I can order a new one?
Please take note that am in CHINGOLA, ZAMBIA

Google "Custom Ribbon Connectors where to buy" and you should find a nearby source.

Or contact Yamaha Support and sales to buy parts.

BUT!!! If those are indeed burn marks in the middle of the keyboard then you probably have much bigger problems.

You have a short circuit between power and ground.

And I hope you kept track of the cable's orientation.

You probably have to replace a board or play hide and seek with surface mounted components.

Plug in a new cable, turn it on, and it will blow out again taking more with it.

There's got be a fusible component somewhere inside and it blew taking out that cable with it and you have to locate and repair the short circuit before you apply ANY more power to the circuit.

Since you don't know what Deoxit is, I think this is way beyond your abilities.
