Re: TV plug came loose inside tv
The damage most be heavy for the power cord to come out with the conector that attaches to the main board,telling you where it goes will not help because most likely you have a broken main board,you shoud get an estimate from a qualified technician.

This is a pretty common problem that is usually an easy fix. There are different causes for this symptom, but most of them involve the high voltage power supply converting from AC (alternating current) to DC (direct current). This is commonly referred to as the "smoke" part of the TV since it has high voltage inside, which is capable of giving you a nasty shock.
Does the TV power on?
Yes - The HV circuit has a capacitor that can go bad allowing the HV to flow backwards into your TV, shorting it out and blowing the fuse in your TV. When you hear the electronic stutter when powering up or powering down, you know that the HV is attempting to flow backwards.
No - The next step would be to take an ohm meter and check your third prong power cord for continuity between each blade. Ensure there are no open circuits which could indicate a failed component in your TV or the wall plug itself. If everything checks out, the next step would be to check your voltage at the plug. Most modern wall outlets should read between 110v-120v. If this is low, it might indicate a tripped breaker somewhere in your home or a failed power supply within the TV itself.
If you get no reading at all from either of these tests, then you have a problem at the wall receptacle or a larger issue with your home's power system.
When I change channels on my cable box, it causes the TV to make a loud click and some of the lights blink. Is something wrong?
Yes - The clicking noise could be caused by a loose connection that is remedied by firmly seating the cable box. If this doesn't fix the problem, then there is probably a failed capacitor in the TV that is causing internal power supply failure. This may be an indication of other issues as well and should be looked into by a qualified repairman.
No - A blinking power light or clicking noise when changing channels on your cable box could indicate a weak connection. Reseat your cable box or check the cables and connections that connect it to your TV for any loose ones. Ensure no bent pins on the cable connectors. If all looks okay, try replacing the cable wire with new one (RG6 coaxial cable). If this does not help, then there could be a problem with the cable box.
Well, there could a be few issues. First thing is to verify the breaker that gives power to that wall has not tripped off in the home's break power panel. If it is not tripped then verify the wall outlet that the TV is plugged into has a reset button, like a GFI (ground fault interrupt) If it does then verify that it has not tripped. If the GFI on the wall plug is tripped simply push the reset button back in and then try plugging in your TV power plug again. Then if that checks out or does not have a GFI outlet, verify that the power plug going into the back of the TV is not loose. Unplug and replug power plug that plugs into the back of the TV in and verify it is securely connected. Lastly, the power supply in the TV might have gone out.
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.
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.
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
This issue is related to the TV's main board not seeing constant A/C power to unit so the board is turning off the TV. When the TV's main board see A/C power back to the unit, the TV will try to turn back on. This issue could be a loose power connection for the TV or a failing part inside the TV. Do other electrical devices work when plugged into the same wall outlet? Try the following: 1. Remove the cord from the back of the TV and reinstall it (perhaps it's loose going into the TV and was not installed correctly). 2. Try putting the cord into a different wall outlet (perhaps it's not a good outlet). 3. Try using a new power cord for the TV. (Any matching cord will work for testing)
If the above did not resolve the issue, then it could be the switch mode power supply and or the main board inside the TV. Both items are easy to change out. I can look up the LG part number for you.
please check the ac plug at the wall and also behind the tv. most newer tv's have a cord like a computer that plugs in the back and they sometimes come loose. are the rest of your electronic components working ? if the ac cord is plugged in, your power supply inside the tv has gone bad. you cannot blame your 2 year old if this power supply has gone bad, this was "NOT" caused by playing with the remote control.
When you are recording, do you hear the vhs tape(motor) moving? Is the tv\vcr combo connected to the same power(electrical) plug with ANYTHING else ? On the SAME wall outlet with anything that generates noise?. Do you have ANYTHING ( electric clock ) WITH a motor connected to the same line\wall\outlet\power adapter?
2nd) Any loose ground [wires that go to any menal part inside TV\VCR will cause problems. Be very carful inside electronics parts and when they are alive [pluged in & turned on], Some times loose VHS rubber bands cause problems by slipping and jerking the tape recording.
