Hi,
Did you mean a Toshiba SD63HK?
You can either disconnect the power from the device and then open it up and check for a fuse on the circuit board near to where the power cord enters the device. Look for a component with an '''F''' designation on the board as fuses don’t have to look like what you think they may look like.
If you cannot find a fuse post some close up images of the board back here. Here’s how to do this. [guide|21499]
OR
You can buy the [https://www.owner-manuals.com/SD63HKTE-service-manual-TOSHIBA.html|service manual] as this should have full schematic diagrams and hopefully also troubleshooting flowcharts that may help you to repair the device.
