- You can buy HDMI cables for less than VND 345,000 ($15) online or at electronics stores.
- Keep the TV’s power cable plugged into the power outlet during installation.
Cable box connection
- The end of the cable will have a needle-like detail protruding in the middle.
- Cable boxes usually have coax cables attached. If Comcast hasn’t installed a cable, you can plug it into a coax wall port.
- If you are using an A/V cable, plug each end of the cable and the corresponding colored port on the back of the box (for example, a yellow cable will plug into the yellow port).
- If you use a receiver that has multiple HDMI ports plugged into the TV, plug the cable box’s HDMI cable into the receiver as well.
- If you are using an A/V cable instead, plug the cable into the corresponding colored port on the back of the TV.
- This input is usually located on the right side of the cable box.
- Instructions for the cable box and remote control may vary by model, so you should refer to the remote’s manual for how to synchronize with the TV and cable box.
