Question about LG 37LP1D 37 in. LCD Television

1 Answer

LG 37in HD LCD tv not responding to any pressed buttons.

I came home and the screen said "no signal" which simply means there is no input. I tried to change (w/ remote) the input to cable and it didnt do anything. I try to change the input on the control panel on the side of the tv and again doesnt do anything. So I try to turn the tv off and nothing. Doesnt change volume, channel... anything at panel nor with remote. I unplugged the television and plugged it back in and if came back on with the no signal again. I plugged a game console into the input that is selected and it worked, but the buttons dont work. Please help.

Based on your description, it appears that you have main board issues with your unit since your controls do not work and some inputs are NG.

SOURCE: LG 42LC7D TV does not want to chg channels after 5 min of use

There are some inductors that are out of spec. LG's original SB said to replace some of these with a jumper, but it only lasted a couple months.

You need to have the Total Main Assy replaced.

your main board has gone bad. Can be fixed, in my shop it would cost about $250. It is a real shame on the industry that these things last about 2 years or less. Hope you held on to your old crt style tv.

Please try this, look in the back of the TV and see if it has a small jack the size of a small MP3 headphone jack labeled with 'IR remote input', if it does, insert a mini phone plug in and out a couple times to clean the switch contacts that selct the front panel remote receiver or the external remote input.
If that still does not work then it can be the remote receiver in the front of the TV is bad.
Please post back what you find and also leave rating if it helps.

If this set is still under warranty return it for repair/replace.
Do you have the correct remote for this tv ?
If it is correct you can do a quick check to see if it is putting out a signal. Turn on a digital camera and point the remote at the lens. Press the power button and others on the remote and watch for a flash on the camera lcd screen.
Check that the input signal cable on the back is on the correct socket. Disconnect the unused input cables.
Go into the menu and set the input signal source to match the connection on the back.
Scan in the stations.

Are the channels found within reception range?

My LG HD tv screen suddenly went green. sound is


Hi,
I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs.
Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture.
If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it.
Thanks.

OK. For all you regular Joe's like me here's the fix--plain and simple! I have Dish Networks HD receiver, an LG Home Theater System (LHB953) and an LG HD Television - although I suspect this applies for most LG TV-to-LG Audio Systems used in combination with a HD TV). My problem lied within the LG to LG setting known as SIMPLINK which tries to "auto-configure" everything between LG to LG devices.

Do this to make your HD TV (using Dish/DirecTV) play it's HD video display from the satellite provider but play the audio over the LG surround sound speakers:

1. Plug a HDMI cable from your satelite receiver's set-top-box to your HD TV. This will carry your HD "video" ONLY. Click "Input" on the TV remote until the HD video signal shows your desired TV channel from your satellite provider.

2. Plug an HD Optical cable (the one with the red laser) from your LG HTS (Home Theater System) to your satellite box. This will carry your HD "audio" ONLY.

3. This is the magic everyone seems to be overlooking. On the LG TV remote, go into the menu options and disable SIMPLINK by setting SIMPLINK=OFF. This feature allows the video and audio signals to be split over 2 different ports: HD video goes over the HDMI cable and the audio to go over the HD Optical cable.

Hope this helps!

It works fine if you plug the surround system SCART lead into the AV2 input. I believe this is a 'smart' scart plug (same as SONY but it is not mentioned as in the literature). The AV1 is only good for inputs NOT outputs as well.

Onscreen controls don't respond


You have five buttons at thee right-hand bottom of your screen (just under thee edge). They are (from
left to right) the Main Menu button, the Down button, the Up button, the Input button and the Power
button (under the light).


To adjust your screen press the main menu button. Once the main menu screen is up, toggle
through it using the Up/Down buttons. Once you see what you want to adjust, move over to the
right side of the menu by pressing the Input button. Now use your Up/Down buttons to highlight
what you want to change. Once it is highlighted, press the "Input" button again. Now use the
Up/Down buttons to adjust your settings.


Once you have adjusted the settings, simply press the main menu button to exit.

Samsung lcd hdtv won't receive signal from fios hd receiver


Hey nothingsfree,

You may not necessarily have anything incorrectly set up, but there are a couple of things that I would suggest trying.

First, you'll want to make sure that your TV is set to the correct input source. Some TV's will require that the input source be changed in order to display any signals from an external device, like your HD-DVR. This can typically be done by accessing the main video menu using your remote control.

According to information provided by the manufacturer, you should be able to change the input source for this model TV (Samsung LN46A750) by doing the following:

* Press the "Menu" button on your remote control
* Press the "Up" or "Down" arrow button to select "Input," then press "Enter"
* Press "Enter" to edit the "Source List"
* Highlight the signal source for the HD-DVR, and press "Enter"

Next, you may want to try updating the TV's firmware. In some instances, simply updating a TV's programming can eliminate any potential hardware or software conflicts between two devices. To update the TV's firmware you will need access to a computer and a USB flash drive. Step-by-step instructions and the firmware update itself are available through the following website:

http://www.samsung.com/us/support/download/supportDown.do?group=televisions&type=televisions&subtype=lcdtv&model_nm=LN46A750R1F&language=&cate_type=all&dType=D&mType=FM&vType=L&prd_ia_cd=02010100&disp_nm=LN46A750

Make sure to read all the warnings and disclaimers available though, as your TV may already have a more up-to-date firmware version than the one that can be obtained through Samsung's support page.

Should neither of these address the issue, you may wish to see if connecting your HD-DVR to a different HDMI input solves the problem. Much like computers, TV's have been occasionally known to have faulty inputs or loose internal connections.

If all else fails, I’d suggest contacting the manufacturer for further assistance. In many cases manufacturers are able to provide over-the-phone troubleshooting support, in addition to having access to a wider variety of possible remedies for hardware problems.

Hope this helps you out.

Sincerely,
Aaron
