Low-cost Battery-powered portable widescreen DTV

Step 5 Test:

Now that your holders are wired together, you can test your battery pack before mounting it to the board. Insert the batteries and snap the "9v to 5.5mm sleeve" power connector to the snap terminals atop your battery pack. Plug the battery pack into the DTV tuner and turn the tuner on (the MG2000 goes on the moment you plug it in). Turn on your DVD Player. You should be getting TV. If not, try changing channels on the converter box and moving your antenna until you do.
