repair Casio 465 sound tone bank
« on: December 27, 2014, 05:49:27 pm »
I have been attempting to repair a Casio 465 sound tone bank, its refusing to turn on, I have verified all the resistor values and cap values and there all good, nothing appears to be burn but when i did first open it i did smell like something did burn, there's a few thing i haven't varied has I have not found a service Manuel for the board inside. This would not be the first time a repair a device, but it is the first time I ask for help.

Thanks in advance for any help

Hi Anora,

What is the model number of the keyboard? 465 sound tone bank is just the series.

Some of the Casio keyboards used a power control IC like LA5668 for power switching/regulation between battery and AC plug pack, this or something like it may be the problem.

Maybe a photo of the PCB would help us to point you in the right direction.
