Panosonic TH42PWD7UY has been hung wall mount until now. Looking for a power cable (cord) and mount.

There are not any easy ways to insert the power cable to the TV while mounted. You can do so but be very careful. I suggest that you dismount the TV for safety reasons. The base of the TV should be stationery and mounted so that you can properly mount the TV back once you have plugged in the power cord.

TRY THIS

1. • 1 Turn the TV off with the front-mounted power button, not the remote. Unplug the TV's power cord from the wall outlet. Let an hour pass before plugging the cord back into the wall outlet. Turn the TV back on with the front-mounted power button and wait until it has fully restarted. Bring up a TV channel to see if the image being presented on the LCD screen is no longer flickering. A momentary power surge can cause the circuitry inside the LG-brand LCD TV to function erratically.
     
   • 2 Unplug the video cable from the video connection on the back or side panel of the LG TV. If more than one video cable is connected to the TV, disconnect all of them. Disconnect the other end of the video cable from the video source device that it's attached to -- a DVD or Blu-ray player, or a satellite receiver or cable box. Blow off the connections on the video source device and on the back or side panel of the TV with bursts of compressed air. Reinsert one end of the video cable into the video source device and the other end into the video input that it was connected to. Turn the TV back on with is remote to see if the picture is now free of flickering. A loose or partially connected video cable can cause the LCD TV's screen to flicker when presenting an image.
     
   • 3 Turn the TV off and unplug its power cord from the wall outlet. Place a power conditioner next to the wall outlet. Plug the power conditioner's power cord into the wall outlet. Plug the TV's power cord into one of the AC sockets on the power conditioner. Turn the power conditioner on. Turn the TV on to see if the picture is now free of flickering. The RF signals in the electric line that the LG TV is drawing power from can cause flicking through interference patterns being generated.
     

check the power cord cable might not properly attached or get broken.

Tries look near the square arm plate that have four screws holding the tv look for a hole with 3 steel prongs that ur tv a/c hole for power cord hook up.But if the tv it is very closed and hook up tight and flust to the wall will not able to hook up a/c power cord must take off wall to be able to hook up a/c power cord.

The base is removed and turned 180 degrees and put back on phone notice the slide tabs are in correct position and can noe be hung by screws or a wall jack. Where the cord plugs in there is a breakout tab, that is the insert to hold the reciever on the phone when hung up.

Power is on then check the cables if your computer is detecting your system.

You are correct in having concerns. Many articles on the web say cut two holes, run the wiring and you're done. This is incorrect, unsafe, and can void your insurance policy in case of a fire.

Many local building codes are based on the National Electrical Code (NEC).

First, the NEC does not allow flexible power cords (or extension cords) to be mounted inside of walls. This means you can't run the TV power cord inside the wall. So a new AC wall socket will have to be installed where it will be hidden by the plasma when mounted.

Second, all wiring run inside a wall must be rated by Underwriters Laboratories (UL) as Class 3, or CL-3. This means the cables between your cable box, DVD player, etc. must all be UL CL-3 rated. Fortunately, CL-3 rated HDMI, Component, Coax, and other cables are available. They are just a little harder to find and will cost a little more.

Third, make sure the wall mount you purchase can handle the weight of your plasma and is securely bolted into the wall studs.

If you follow this advice, you will pass inspection by even the most picky home inspectors and insurance companies.

step-1.
