Question about LG 42LC2D 42 in. LCD HDTV

1 Answer

LG 42in LCD. All of sudden this weekend the sound goes off. I could have swore I saw the mute signal pop up then right back off the screen. My tv is connected to Uverse, a soundbar and an Xbox 360 and those all work fine. It's just the tv's sound. And I've gone and made sure all speakers are on. If anyone can help, thanks.

If it works with the 360 and speakers are on---disconnect power from the TV and the box for the uverse and after a wait power them back--its possible a glitch from box if used caused this.

Also if box has audio/video outputs connect from them to a rear input on the set to see what happens.

  • IF THE SOUND HAS GONE FROM TV OUTPUT BUT NOT FROM AUX OUTPUT, IT LOOKS LIKE IT MIGHT BE OUTPUT AMP ON SOUND BOARD THAT HAS PACK IN. iTS A REPAIR JOB. YOU CAN EITHER REPLACE OUT TRANSISTOR IF YOU KNOW WHAT YOU ARE DOINGAND CAN GET THEM , REPLACE COMPLETE BOARD AS COMMON PROBLEM.

Need codes to set tivo to lg tv


Code 0011 worked on my LG 42in LCD.
Thanks to Priya darshan for the codes.
BTW, code 0001 only partially worked ("Mute" did not work).
I phoned Tivo help desk (I am in New Zealand) and they confirmed that LG is still not listed as one of the brands of TV from the list of choices.
Simply choose any of the TV's listed and start entering the 4 digit codes on this site (or others found via Google) - one will work.

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.

3 year old 42in LG LCD TV scrren went blank


You will either have a fault with the inverter board which drives the backlights or a faulty backlight in the screen. If the problem is a backlight then a replacement screen is the only cure. One or the other is breaking down after it has been opn for a certain period of time, have an engineer call out & check with a tester if it is a screen problem.

LG 47LC7DF LCD TV turns off with a pop then turns back on.


Sounds like a overheating issue. Try facing a large fan blowing across the back of the unit and see if this changes anything. If it does, it might help to blow the back out with compressed air as dust might be helping it overheat.

No signal report


Ensure that your "video output" on the laptop is on. You usually have to press the Function key (FN) and one of the "F" keys (F1,F2,F3,F4, etc..), The one with a little monitor icon on it. This will toggle the video between the lcd and the TV.
