My lg xcanvas 42 plasma


You need to reach the Option menu, and to set the language. You will have to do this working on the Korean menu. I hope that the pictures below may help:


Press MENU button on remote, and go to OPTION menu, which is the one with a tag picture, right on top of the padlock pic.

Use the arrow buttons to select language. use arrow right to confirm and up and down to select.

Below a manual for this model:

I have a 42 inch lg plasma,and everytime i hook up

ok, have you tried hooking up your PS3 to a different tv and it work? if so, you may have to change the settings in the PS3 to fit the LG tv. or, it may be in the menu options of the tv for a specific channel or setting. reading directions for hookup is a big help too:P

This could be 1 of a few things here. Without opening up your set and trying to look at voltages or indiciator lights I couldn't tell you exactly without some more info.

Without looking at it myself here are my thoughts and where I would first look at.

It may be a main board because:
1) Main board processes all your audio/video signals. Bad main board means bad video processing. Could do that. Especially if the main board is not sending the right signal or a bad signal to the rest of the boards so they don't do their jobs. 

It may be a power supply because:
1) Power supply is well, the power supply. If it's sending inadaquete voltage to the main board you may not be recieving enough juice to keep that main board doing your video processing or further up the line keeping enough juice flowing to your TCon board to keep it telling things where to go and what to do. The power supply sends voltages to your Ballast board(controls your lights) and to your main board through which power is supplied to your TCon board via a LVDS line and a +12/+16V signals. If the power supply isn't pumping out enough juice to keep the TCon or Main Board running, it could be a problem. By the same token it could be that your P/S isn't sending power out to your ballast board. 

It could be a TCon because:
1) If the TCon is bad, you won't get your pictures. This could be the TCon board itself or the LVDS cable from your TCon to your Main. However, with few exceptions, if it's a bad TCon you're looking at a total panel replacement. 

It could be a ballast board because:
1) The Ballast Board controls the lighting behind the LCD screen. If this isn't working right you won't be seeing much of anything without that back lighting. If this is bad, it's a panel replacement. These are not field replaceable items by LG. 

Based on the symptoms, without more data or a eyes-on view of it, I would say you're most likely looking at a Main Brd or PSU problem.

To fix the problem, try turning off the TV and unplugging it from the outlet. Once unplugged, push the power button and hold it down for 1 minute. Then turn the TV back on and rescan for channels.

If the problem persists, contact LG customer service immediately as there is a problem with the memory card. The device is unable to retain scanned channels for immediate feedback.

All LG LCD automatically comes with a 1 year manufacturing warranty. You would have to provide proof of purchase to show when it was purchased. Hope this helps. The Guru

Samsung lcd 32 inch tv has vertical lines in color about 4 inches wide all over the screen and it has no picture but it has audio

Only boards are sold and no parts- a 32 inch may not have even the boards or be cost effective to repair----suspect main board here.

The tv sensor is not working on my 42" lg lcd hdtv

Believe it or not...THIS WORKS!!!! 

 Look on the back of your set for an external remote jack. It should be the same size as a small headphone jack. If it has one, use a spare headphone plug or your headphones, and plug them in and out about 50 times. This will clean the tarnished contacts and make your remote sensor start working. Your remote sensor goes through a switch on this jack.

42 in LG LCD TV turns off by itself

Found that TV started switching off by itself. Would try to come on..green light blinked for 2-3 seconds, tv came on (with picture and sound) for 1 or 2 seconds and then it would turn itself off. Found that the issue is with one channel only. If you are facing this issue....try quickly changing the channel the moment it comes on. You can do it either with remote or with the TV buttons directly. also in the same logic, if this is still happening, try changing the source to another (rgb-pc, av1, av2 etc). Basically change it from whatever input it is on currently, if changing the channels does not work. My symptom was that the tv made a loud 'TIK' 'TAK' sound which is louder than normal.

Do a first time installation, move the TV or bite the bullet and either buy an external aerial or extend the main house aerial cable to reach the TV. assuming your TV has no signal where it is now

42" Lcd problem

I belive the repair shop might be try to get more money from you
if you enscrew the back of the tv ( with the tv unplugged ) look for a flat wirestrip thats not connected
I think they either forgot to plug in that video wire or they did it to make money from you

did it work fine before the dim screen or did it come back to you like that?
