The front of your computer is the Front Panel.
The area of pins on the motherboard, that the main wires from the Front panel go to, is the Front Panel header.

Looking at the Front Panel header it is parallel to the outside edge on the bottom/right of the motherboard.

13 pin header.
6 across the Top row with 1 pin missing, 7 across the Bottom row.

Top row is numbered EVEN
Starting on LEFT side coming across to the Right, Top row;
Pins 2, 4, 6, 8, No Pin, 12, and 14.

Pins 2 and 4 have a Green area

Step 1
Download Original]'>Construct your legs by nailing through the 1x3 legs into the edge of the 1x2 legs with 2" nails and glue. The legs will be positioned with the 1x3s to the front, 1x2s to the side, as shown in the diagram.
Step 2
Download Original]'>Start by marking each of the legs 5" from the bottom of the board. This will be the bottom of the side support, C. Nail C to the legs, using 1 1/4" nails and glue, from the inside.
Step 3
Download Original]'>Now add the stretcher, D, centering D on the support, C, but keeping the top edges flush. D will lay flat, with the wide side up. This is demonstrated above. Use glue and 2" nails, nailing through the support, C, into the end of D.
Step 4
Download Original]'>Add the side trim pieces, E. First, nail through the supports C into E, using 2" nails. Then nail down the length of the stretcher, taking care to keep the top edge of the stretcher (D) perfectly flush with the top edge of the stretcher support (E). Use glue and 2" nails.
Step 5
Download Original]'>Now use the 1 1/4" nails to nail through the back of the side apron pieces, F, into the legs. Use glue. Keep top edges perfectly flush.
Step 6
Download Original]'>Do the same for the front and back apron pieces, G, as shown above. Nail through G into the legs using 1 1/4" nails and glue. Keep top edges flush. Take a minute to check for square
Step 7
Download Original]'>Now add the base top, piece H. Keep the front and back edges flush with the legs, but let the sides overhang 4" on either side. Nail into the legs and the apron using 2" nails and glue.
Step 8
Download Original]'>Use glue and 1 1/4" nails to attach the breadboard ends to the base top. Keep all outside edges flush.
Step 9
Download Original]'> I recommend not cutting the final piece, J, unitl you have taken an exact measurement. Add the final piece, using glue and 1 1/4" nails.
Finishing Instructions

1. Remove the 5 screws from behind each speaker
2. Grasp bottom center of plastic panel and "pop" forward. Swing upward to remove.
3. Remove 4 screws from the wooden panel in center.
4. There is a "black box" in the very front of electronics. It will have torque paint on the 2 rows of 3 screws. top row is labeled "focus"
MY TV would go green before going black. Volume still worked.
5. I turned the center bottom screw (marked "green") appx. 1/8 to 1/4 turn COUNTER clockwise.
Plugged TV in and it works fine.
