In some cases, the legacy SafeCapture HD does not work after installation or stops working after maintenance.

If none of the LED lights are illuminated (not even the green power LED1), the problem usually relates to the power source or power supply. In most cases, the problem is a loose, blown or improperly installed fuse.

If you are having a power source problem, verify that the fuse is intact and is properly installed.

Disconnect the Power to the SCHD!
Before beginning any work on the SafeCapture HD, turn the power switch off and unplug the device. Simply turning the device off does not remove the device from the AC power supply.

Remove and Inspect the Fuse Block

The fuse block for the legacy SafeCapture HD is a red plastic block that resides to the left of the power switch in the power switch assembly on the back of the device. Follow the below steps to remove the fuse block and verify the fuse is installed correctly.

1. Open the cover to the fuse block using either your fingers or a flat-head screwdriver. The picture below shows the fuse block being removed from the power switch assembly.
   
2. As you remove the fuse block, note the positions of the following items:  
   1. The fuse resides in the top of the fuse block, positioned in the fuse slot so that it sits toward the inside (front) of the legacy SCHD.
   2. The horizontal metal bars, shown on the left side of the fuse block in the picture above, are on the side away from the power switch and power cord connection.
3. Once the fuse block has been removed from the legacy SafeCapture HD, check for improper assembly of the fuse block. The picture below shows a fuse block with the fuse installed correctly. Notice that:
   1. The "inside" end of the fuse block (the end positioned closest to the front of the legacy SafeCapture HD), has flat metal prongs, similar to those on a power cord. These prongs plug into the key for the fuse block inside the power switch assembly.
   2. The slot for the fuse may be longer than the fuse you are using. The fuse block is designed to work with two different types of fuses, of different lengths. The picture below shows the shorter fuse.
      
   3. The fuse is placed in the slot so that one end of the fuse is located at the pronged end of the fuse slot. This is the end of the fuse block inserted into the legacy SafeCapture HD first.  
   4. Underneath the "inside" or pronged end of the fuse slot is a metal contact. This is not an electrical contact. It is a spring that provides tension against the fuse from underneath.
      
4. Inside the switch assembly (from which you removed the fuse block) there is an electrically-active contact. When a properly configured fuse block is placed inside the power switch assembly, the tension spring presses the fuse against it. This helps ensure constant contact with the fuse.
5. Once you have finished inspecting the fuse and block, and ensuring the fuse is intact and the block configuration is correct, re-insert the fuse block into the power switch assembly.

If you still don't have power, you may have inserted the fuse block incorrectly. This will not cause permanent damage to the legacy SCHD, but you will not receive power until the fuse and fuse block are installed properly.

Check for Improper Assembly

There are a number of easy-to-miss fuse block items that will cause the legacy SCHD to not receive power until they are fixed.

Fuse Not Properly Placed in Fuse Slot

The fuse slot is designed to accommodate two different size fuses. One is longer than the other. If you have the shorter fuse, it may be installed at the wrong end of the fuse slot. The fuse will snap in as you expect, but because the inside end of the fuse is not in contact with the metal spring, it is not being pressed against the electrical contact inside the power switch assembly. The picture below shows a fuse improperly installed into the fuse slot.

As identified in the above picture, notice that:

• The left end of the fuse is not located at the pronged end of the fuse block.
• The metal spring is visible. If it is visible, it will not press the fuse against the electrical contact inside the power switch assembly.

If this is the problem, remove the fuse and re-insert it into the fuse block, placing one end of the fuse at the pronged end of the fuse block.

Missing Metal Clip

If you flip over the fuse block to view the underside (the side opposite the fuse slot), you should see a metal clip, as shown in the picture below.

The clip is required to complete the electrical circuit. While the clip is typically well-secured to the fuse block, it is possible to accidentally knock it loose while handling the fuse block. If this clip is missing, you will not get any power to the device, although the device is not harmed.

Re-attach the clip to the fuse block. Place the clip at the pronged end of the underside of the fuse block, with the open end facing away from the prongs, as shown in the picture above. It should snap into place. This clip resides on the bottom of the fuse block and cannot be clipped onto the top (fuse side) of the fuse block.
