Unless you are good with a solder iron & can recognize were the center pin of the coaxial went you will need to take that to a shop, even then there is a possibility that you have damaged the board inside the tuner & may need a replacement

My 32inch lcd tv keeps flickering it started all the sudden


TRY THIS

    • 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.

No volume from cable


Hello!
First step: reset your cable box by unplugging of the power supply or unplug power cord of the box. If that's an old fashion big gray one or black one with additional power outlet for TV set, there is a power cord goes into. Unplug it, then plug it back in within 1 minute. not the TV itself, but the cable box's power cord. This will reset it. If you have more modern one or small one for non HD TVs, they have external power adapter, which plugs into those boxes.
Pull that plug out for a minute, then plug it back into. That should take care of your sound issue. Known problem.
Good luck,
Let me know if that took care of your issue.
thanks,
Alex.

Hi behind my new lcd where the power cable is the plastic as melted was shold i do?


LG TVs seem to have a problem with easily loose power cords. A loose cord probably led to an electrical arc, which is probably why you have melted plastic. Plug in the cord tightly into the TV and see if it'll turn on. If if works properly, you can use it as is; just find a way to make sure that the plug doesn't have any strain. What we did was tie the cord to the back of the TV about a foot away from plug; this way, when the power cord gets pulled, when force is resisted by the tie and not the plug itself. If there is significant damage to the cord, you'll want to remove the screws on the back, take out the back cover and replace the whatever damaged parts you find.

Red vertical line on the screen due to external shock


This is most likely caused by the cable on the T-CON board being bent out of place by the shock.
If you know how to work on electronics or have a friend with knowledge/skill you can fix it.

DO THIS ONLY IF YOU KNOW HOW TO WORK WITH ELECTRONIC EQUIPMENT.

REMOVE THE PLUG FROM THE WALL. REMOVE INPUT signal cable from set.
REMOVE THE POWER CABLE FROM THE SET.
>Lay the set down on a flat cloth covered surface.
>Remove the back cover.
>Remove the shield covering T-CON board. This small board is located in the center near the top.
>Move the cable(s) connected to the T-CON around.
> Set the tv upright and make sure it is stable.

DO NOT TOUCH ANYTHING ON THE BACK
.
ATTACH INPUT SIGNAL cable to set.
ATTACH THE POWER CORD TO THE SET.
PLUG THE POWER CORD INTO THE WALL.
>Use the remote to turn the set on. If the vertical lines are gone, THEN TURN the set OFF.
REMOVE THE PLUG FROM THE WALL.
REMOVE THE POWER CORD FROM THE SET. Remove signal cable.
> Lay tv back down on table.
CAREFULLY REPLACE THE SHIELD over the T-CON.

Replace the back cover etc.
Now you can reconnect the input cable and power cord.
SOMETIMES THE IMAGES can get worst and you have to repeat moving the cable around. In the worst case you can dis-connect and re-connect the flat cable WITH THE SET UNPLUGGED.

I believe the T-CON may sometimes be called LVDS and look similar to;

It's very likely what you call the flat plug is the video cable. (Picture #1) below. The corresponding cable looks like (Picture #2). The other cable (A/C) by elimination plugs into an electrical outlet. Are you seeing a cable other then this one coming out of the back of monitor? d82bfa4.jpg697a779.jpg

Trying to undo a T.V main plug


Hello,

If the cable is attached to the television, I don't recommend trying to detach it. Opening the TV voids any warranty, and is also unsafe for you and the TV. You can try feeding an extension cord through the hole, and tying up the attached cord behind the TV. It is usually not visible, and works perfectly, with no modification to the Television.

Hope this helps you...

No surround sound when attaching hdmi to TV


Try running the optical TOSLINK cable from the TV to the receiver. If the TV doen't have a digital optical output, then try going into the menu on your cable box and setting the audio output to the digital optical out. Also check your TV menu and make sure NETCOMMAND is diabled. Some of your newer HDTV have Netcommand that allows the TV to control other devices through the HDMI cable.

Solution steps:

1. Make sure that the cable is not plugged into the mains receptacle.

2. Open up the unit

3. Inspect the board. Look out for a glass fuse rated about 3A/220V near one corner of the board. It is close to the mechanical ON/OFF switch on the TV. The cable normally plugs into a socket made up of two vertical pins an inch or less from the fuse. Sometimes these are marked with a squiggle (~) or two (~~) to signify that the mains power goes there.

4. If the cable terminator (end of the cable opposite the mains plug) was cleanly pulled out, then well and good. In that case simply plug it back in. If not (i.e. the cable is damaged, then you may have to remove the terminator and solder the cable directly to the board.

5. To pre-empt any further "pullings", make a knot on the cable inside the TV where the cable comes out so that there is some resistance to the pull.

6. Close the unit and enjoy.
