Does not power on my machine - Sony BM-147 Desktop Cassette Transcriber / Recorder

You tried disconnecting the stitch regulator?


No, try machine without regulator.


Yes, make sure you have power at the wall socket. Unplug sewing machine and plug in a lamp, radio, or vacuum to test for power. If power at wall socket, then plug sewing machine back in to wall socket. If still no power, disconnect and reconnect power cord at machine end. If still no power, try cycling the sewing machine ON/OFF switch a few times.


If still no power then likely the internal fuse or other.

If your Brother machine does not appear to have power,then check whether or not the date and time appear on your Brother machine's LCD. If anything is displayed on your Brother machine's LCD, then it is most likely receiving power.If your Brother machine's LCD is blank, continue to Step 2.
Verify the Brother machine's power cord is connected securely to the power outlet. If you are using a surge protector, extension cord, or power switch, disconnect it and plug the Brother machine directly into the wall outlet.
Please note Brother strongly recommends that you connect your machine to a surge protector.Because To protect your investment against power surges and lightning,
In particular, we suggest that you use a surge protector that is compatible with both standard A.C. power cords and telephone line cords. Surge protectors equipped with telephone jacks will assist in insulating your machine from any power surge that might travel through a telephone line.
If the Brother machine is turned OFF, its LCD will be blank. Please make sure the Brother machine is powered ON by pressing and holding the On/Off or Power Save key. This key is located in the upper-right corner of the control panel.
If your Brother machine's LCD is still blank, connect it to a completely different, known working power outlet. If the Brother machine powers up, then the problem is related to the original outlet.
-OR-
Confirm the power outlet is working by plugging another known working device (a lamp, radio, etc.) directly into the same outlet. If the other device does not work, the problem is related to that power outlet. If a wall switch controls the outlet, verify that the switch is ON.
If your Brother machine still will not power on, please contact Brother Customer Service.

its not transformer or machine problem at all.all the connections are also proper.its the power issue the required power to the machine is not getting from the electric outlet.just call the local electrician and check out the power supply voltage from the electric outlet.and power required to the machine which will be listed on the machine.if more power is required he will connect the over power IC and get the machine work.if less power is required he will connect the RESISTOR and lower the power to the machine and make it work.
