my lg tv don"t have picture just sound,what can i press on the controlpanel?

hi madame anna. do you have a warranty on this set. if you do anything we tell you is obsolete. make them honor that warranty and get someone with you that can help. sometimes the stores will try to rip you off.

Must be the IR receiver usually is soldered on a circuit board. Time to call your warranty..

Most preset codes are 1234 or 0000 or 5555 and 8888 these are not srevice codes

first buy the right bracket for weight of tv there is 4 big black screws near center of tv ( IF FITTED )take them out place bracket over 4 screw holes then use the 4 screws you took out make sure they are tight ( DONT FORGET TO TAKE STAND OFF )

take back off and on mains power board check for blown cap you will see a raised top

Hello Blindrid,
What I would suggest you do is Press your MENU button on the tv remote, Then down to SOUND and then Turn the AUTO VOLUME to OFF. Then come out of the menu screen.
Just to check that it has all work correctly. turn you volume upto a certain number for example 25
Then turn your TV off the turn it back on. Wait until it is displaying a picture then press the volume button Once either up or down and you should see that it will go to 24 or 26 depending on what button you pressed for the volume. This will keep your volume set to whatever you had it on before you turned the tv off.

Hope this Helps Please leave a thumbs up.

Cheers

please follow the steps below:

TV
RED + SELECT
TV
0056

try the volume if this works then press SELECT to save the code. If not then press TV again then the volume. repeat this step until the volume works then press the SELECT button to save the code.

Right you said in your post that it only works part of the tv, what this is when you have saved the code into the remote it is very close but not the correct code for the LG Model you have. So imput the code as mentioned above but when your checking the volume dont press SELECT straight away try the help button. power button etc then save that code if it works them. when it is the correct code you should be able to press the TV button then power = power . Help = changes av / source. Number button change channels etc. On certain tv's on a sky + or hd the pause/play changes the aspect ration on the tv aswell. When this sorts you out please leave a thumbs up cheers

first of all I would like you to press the blue sky button on the top of your remote. Now press you tv guide button. If this has sorted it Great if not read on!!

what I am going to talk you through now is resetting your remote:

TV
RED + SELECT (flashes twice)
999

now press the blue sky button at the top of your remote now try the tv guide button. this should work no problem now.

now to the small matter of tuning your remote back in to work your volume etc

please follow the steps below:

TV
RED + SELECT
TV
0056

try the volume if this works then press SELECT to save the code. If not then press TV again then the volume. repeat this step until the volume works then press the SELECT button to save the code.

cheers

yes it is possible but I caution you to get estimates and then compare those numbers to the purchase of a new tv as that repair is pricey.

Yes. Go to menu, select AIR make sure it is not set to CATV unless you are using cable,
Then find the "autoprogram" option, select it and it will scan all available channels.

replaced main board

Sounds like a defective main board, there are only two boards in your set. here is a seller of this part link they are out of stock but you will have the part # in case you want to repair it yourself I’m happy to help further over the phone at https://www.6ya.com/expert/eric_ab7c09ec01841771

Your going to need to LCD panel which you will most likely have to order directly from LG, chances are that it will cost just about the same as the TV brand new. Its fairly easy to change as long as u can remember where the circuit boards go from the old panel.

thats what happens to me but there is because theres an emerency alert thing so just stop watching tv there so it can stop maybe check its battery

I have a LG tv set. When i press the tv/av button on the remote my tv shows av1, av2 earlier but now it is showing only av. So i am unable to watch my dvd player. Need help.

the main total assy is at fault. unplug the tv for 5mins and plug it back in. if it does not clear itself it needs factory service

Yes, it is possible the settings from your cable box maybe set to the wrong ratio eg:letterbox. Depending on what type of box you have, look in the cable box menu for a settings option, then change the aspect ratio to a different format.

Some models are just that way. I would invest in a small surround sound system for them.
