Question about LG Televison & Video

Open Question

Antenna/cable-in broke On my LG 47LE5400 TV I am trying to hook up the Mohu Leaf Plus. My antenna/cable-in port on the TV is loose and I have to hold onto it while tightening the Leaf connection to the TV. I am getting reception, but it's all or none, leading me to believe that my antenna port has a loose connection (especially since the port itself is loose). I removed the rear panel of the TV and found a part number on the port: MEZ46739123; but when I search for that, it brings up a complete in-put board. I am trying to get into the small compartment on that board to check the antenna port connection, but I cannot figure out how to open it. Can it be replaced separately or is it all one piece? How can I fix this port to get TV reception?

SOURCE: tv coax f connecter is broke off cannot hook cable cord on it. or antenna

I looked up the manual for this TV and it has composite (RED, WHITE, YELLOW) and component (RED, GREEN, BLUE) connectors as well.

Are you using a cable or Dish box? If so, those boxes usually have output in Coax, Composite, and Component formats. You could just run that type of cable. If you use Component you will also need another cable set (RED, WHITE) for audio.

If, on the other hand, you do not have a cable box and you are using your TV's tuner you only have two options. You can repair the broken connector or you can route the Coax through an inexpensive VCR which will allow you to convert it to Composite cables. In this case, however, you'll have to use the tuner in the VCR, not the tuner in the TV to change the channel. Sorry it's not the best of news.

I want you to know that I'm not paid for this. It's a strange hobby I know, but I like to help when I can. While I cannot physically repair you TV, I hope you've found this information at least helpful and will rate it positively. If you have more questions please don't hesitate to ask. Thanks, and good luck.

SOURCE: LG 42PX4MVH PLASMA TV - Sound but no picture.

I have the same issue with my LG 42PC3DVA and I narrowed it down to the Y SUS board. After a little research there are a few items that are prone to go. The ceramic fuses (as you found), sometimes the capacitors on the Y SUS, Z SUS, and power supply go along with them You can tell because thy will be bulged at the top instead of flat. I replaced a few of my capacitors - they are only $0.89 each so it was MUCH cheaper than a board.

The other thing that is common on the Y SUS in particular are the FETs (also called MOSFET). They can be replaced if you are good with a soldering gun but they are static sensitive so be grounded. They are also a bit tricky to test so you may want to do some research on how to determine if this is the issue... or you can just replace the whole board.

It's all digital now - don't forget.
You need to switch from cabel to antenna first.
Play around with menus - it has to be there. Or just do areset if there.

SOURCE: off air antenna hook up

You probably have to set the tv to run on the input jacks your antenna is plugged in to. In other words these newer tv's have 2 or 3 inputs and they only run on the input it is set on, if not the right one you must change the setting. On mine there is a button next to the on/off button on the set which is inputs, keep pressing that button and it cycles through inputs till you get the right one. When tv first comes on it flashes the name of the current input on the screen--think they all do that. If input is hdmi, it refers to the hdmi socket, if composit (I think) then it refers to the rca jacks that are red, white, yellow, may be more than one of either. In this way you could have cable on one input, a video player on another, and cable on still another by switching desired input. I use a UHF antenna but it didn't work till I got the right input and then searched for stations studying the menu for station setup, have to set up the stations first, it will configure settings for each station, and have it do that before you can expect to find and receive stations. With correct input you should get a blue screen or something with printing if input is right, click your menu button and will see the menu and then find where to configure stations setup, otherwise it is totally black and nothing happens, nothing responds, that's the wrong input.

Can you hook up the tv directly to the antenna? We do not have cable. If so what kind of cord/cable do we need?


That will depend on what sort of antenna you have. Radio Shack will have a flat wire to F connector if that's what you need. if you are in a urban area, I'd suggest a leaf type antenna. I personally use Mohu brand amplified ones on each tv. No more cable bills,

The antenna may not have sufficient gain to detect the other channels. Is it amplified? You may have to try placing the antenna in different positions to receive different channels.

Did attatching HD Antenna fry my HDTV?


"the screen is nearly constantly with the exceptions of..." What does that mean?
If your antenna has a power supply it may have malfunctioned and fried your TV's tuner. Forty inch flat screens go for about $400 and up these days.
It could also be a coincidence, that the TV was expiring just when you hooked the antenna up.
