Hi friends, I need your help in whichever way possible. I’m looking for where i can source the internal power supply and the motherboard for e443.
Or any one familiar with the power failure which is common problem with the above mentioned Keyboard.

I don't know if you can buy the actual motherboard; you might need to buy a used PSR-E443 for cheap that has some other problem-- like a busted LCD screen or broken keys-- and cannibalize it for parts.

On the other hand, if you need to replace individual components on the motherboard, you might be able to get them from an electronics supply company that sells those types of components. Do you have the Service Manual for the PSR-E443? It should list all the individual components.

Welcome.

Honestly ditch the bust 443 it simply is not worth the time and effort (since it is a good few years old) and buy a new S/SX series from Yamaha or a PA by Korg, you deserve to treat yourself.

Repair bills these days often outweigh replacement item..
Cost v cost . . new item wins.

Unless the broken item is valuable then maybe worth fixing.
