Need schematic for Boss BR 600 digital recorder. My power input has failed. need value and direction of diode to replace Q47 chip.

Internet mod says replace failed Q47 with a 1A/40V diode- socket is marked D2. My tech says putting it in the wrong way could cause further damage. Any help/ advice out there?

To be sure you need a schematic. You can actually take a look at it to see if is labeled or check polarity with a meter.

Remove power supply or battery for 5 minutes. Apply power while holding the on switch in, this usually resets most electronic devices to their factory default condition. Then look again.

Hi I have a boss 1600br that will not power up. screen just blinks.I've .The br 600 model has trouble with a po wer diode causing it not to switch on. Could this also be the same with a br 1600?


Make sure you're using the correct power adapter or that the one you have is not malfunctioning. I've experienced Roland/Boss equipment blinking (and restarting over and over) when they are not receiving enough power. Sometimes even the resistance caused by too long of an extension cord can cause this to happen.

No power when switch on with 9 v DC transformer


Is the transformer you are using the original? or are you using one that you picked up. If it is not the original, you have to make sure that the voltage and ground on the plug matches what the unit needs. Some adapters reverse the + and - on the tip and sleeve on the plug.

Power failure?

First check the power supply / adaptor to ensure this is working correctly. Measure the voltage using a multimeter - if this is correct move on ( if not replace power supply )

Does the keyboard work if you hold the plug in the socket or move it slightly ? If so this is a common problem as the power socket on the pcb fails at the solder joint and will need to be repaired / replaced.

If this appears to be solid then you may have done some internal damage by either plugging in a power adaptor with a too high voltage or wrong polarity. If this is the case you may have blown some circuitry inside which controls voltage regulation.

Please report more if you have more information.

I have a Yamaha PSRE413. on/off does not work with adaptor, but works with batteries


If you are using the correct adaptor then the most likely reason is that the socket where the adaptor plugs in has broken away from the circuit board and will need to replaced/resoldered.




if you need a socket Google : Yamaha PSR power socket ( KPA3 / PA130UK / EPA3 ) (LB30226R)


OR if you have used the wrong mains adaptor and the polarity was reversed you may have damaged the diodes / voltage regulator on the power input.
