Hello
You can't control all the functions of this TV with a direct TV remote control. Some functions will be innoperative, as signal frequency send by the orginal remote and direct tV remote are different. When you use its original remote, all functions you set will be memorized as you switch OFF the set, where when use an other device's remote, this memorize function won't activate when you switch OFF the system. So you will have to reconfugure all the items again for each turn ON. OK.

Hi,
Do you get green picture in all inputs of tv? Please unplug tv from wall socket for minute to get it reset, replug back in, turn it On and check.
Let me know to diagnose the problem.
Thanks

I'd check out the IR board on your tv. If you have electronics experience open up th etv find the IR board - trace it back to the AV board make sure all connections are plugged in good then if that doesnt work I'd replace the IR board first. That would be the cheapest part to replace. Also it could be the IR on the remote - but if the codes you used to program the programmable remote are known good for your model i'd look at the tv first.

thanks,
michael

Hello
Press "Menu" and select "Optiion".
Press "Enter" and select "Language"
Press "Enter" and select "Menu"
Select your desired lannguage. From this point on, the On-Screen menus will be shown in the selected language.
Press "Return" to the previous menu.
Press 'Menu" to return to TV viewing.
In the option window, if the caption function is set to OFF make it ON.
OK.

NO... check and see if all 4 bolts on bottom of stand are tight. IF it is tilted and tight, remove the stand from the internal slide, re install. Sometimes it gets lodged behind the proper mounting point.
Please leave feedback

Remove the actual stand (4 bolts are hidden in a sunken down spot for them on the back of the tv.

Once the stand is out of the tv, look down to where the swivel joint is at, you should see 4 screws that are going towards the bottom of the stand, those will be the loose screws.

I just fixed mine.

Hello
Either your TVs speakers or its output IC may have damaged. To confirm it, just up the volume of your tV, and try to hear the sound if any. If it feels like dostorted or very low-hard to hear, the speakers must be suspected. If there is no sound signal at all, output IC should be damaged. To confirm whether the sound detecting section is Ok, just connect your TVs audio output sockets at the rear of your TV with an amplifier or so, and rise the amplifier voluem, to get sound through it. If you get sound in this way, make sure that the above daid two items. Fist check the speaker, by connecting an external speaker in place and listen to it. If it also doesn't get the result, surely the output IC of your TV has damaged, and should be replaced with same type and number. OK.

what is the number of the blinks of the red light?

Tries tv unplug,replug it back like about an hour later.By letting tv resetting itself.Tv should be working again.If still have the same problems.The power supply board is the causes and problems.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Hi there,
They sell LG screen parts at:

http://www.alllgparts.com/

Just type in the model number on the left hand side, under appliance search and it should list the parts they have in stock.

Hope that helps.

maybe just poor speakers.....had a similar problem with an old sony. Replaced the speakers twice and always had a noticeable buzzing. Try running external speakers (computer speakers will work) at low volume to see if you hear it in those. If so, you may have sound board issue.

Take it back to the shop for a replacement.

On all modes? Did you try leaving it unplugged for about an hour to let it reset itself. Also try using the on screen setup to reset to factory default.
You can also try this:
Let verify first to narrow down to where the problem can be, attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find. You may be better off if the sound does work through the PC speakers, to get the TV repaired; it will be more than $100 and up.

Not so sure but looks like is seted up on HDMI input. So when you start it is trying to find and decode the signal but probably there isn't one. So try to switch it on another imput like TV or AV. Is there a death screen also, like no light no anything?

TV needs service.Main board or power supply has failed. If you havent already done so, make sure all of the connections to the television are going into the correct places.

Hello there,

This is a common problem but it is not usually a fault with any of your equipment. It is more of a "Battle Royale" between aspect ratio and resolution settings.

If you are unable to get the picture size correct using the aspect ratio settings on the TV, it is usually because the aspect ratio or resolution of an external input is set incorrectly. Similarly it may be that the settings on the TV and the external input are not in harmony with each other. The settings need to match or you can get some very strange results in terms of picture size.

The external input might be a cable/satellite receiver or a digital tuner/converter.

If you have one of these external inputs connected, set your TV to FULL / 16:9 and then go through the various aspect ratio settings on the external input one at a time and note the results. When doing so, switch the TV to either a sports channel where you can see the scores are partly cut-off or a news channel where the ticker is disappearing off the bottom of the screen. It may not be obvious on other channels when you have selected the correct setting.

If you need further assistance, please reply to me from within this page with details of the brand and model number of any external input device you are using and the type of cable you are using to connect it to the TV. The cable can have some bearing on which settings are correct, particularly when HD is involved.

I will then be able to tell you the exact settings for your TV and any external input when they are used in conjunction with each other.

Hope this helps.

BElectric
