There are red,white,and yellow wires at the back of the T.V. Make sure
that the yellow wire is plugged into the yellow plug in hole, white wire has to be plugged into the white plug in hole, and the red wire plugged into the red plug in hole.Sometimes for the red wire you have to plug it in a black plug in hole. Make sure your T.V. is connected to you reciever. If this doesn't help I'd try calling somone to fix it for me.

SOURCE: 42LG5010 When switching the telly

I would start by shining a torch at the screen when the TV is turned on and see if you can see a faint image in the background, if you can then this would more than likely be down to your inverter board/s
If not then if you have no picture and no sound at all then i would put this down to your main AV board (the one with the scarts and inputs on )
These guys have all boards for this TV

hi the problem wouldnt be the screen instead your probably right with the video card if the screen was dead it would stay black but with it changing slightly you know the screen is gettin power.
When you press the controll does an led flash on the telly to tell you the controll is working just incase the telly is stuck on an av channel.
If you have got a dvd player hooked upto the telly switch this on with the telly on and see if the telly will work using the dvd player this would rule out the fault being with the ports on the telly not picking up the signal.
If this still dont change anything then it could either be a resistor gone or a couple or it could be what you thought with the video card/controller but their is no way of knowing without testing the resistance at certain points on the board but it deffinately wouldnt be a problem with the screen so it shouldnt cost to much to repair.
It mgith be a case that the telly has overheated and blown a resistor thse can be brought for pennys but locating will be the problem let me know what you want to do and wether you are considering doing the repair yourself if you are you will need schematics to follow off and also multimeter to test resistance at certain points on the board.

Lcd tv light flashing but no picture or sound


If you removed power by turning off power itself to the set instead of turning it off by turning the set itself off---that is not a good thing to do.

When power is restored a surge can and likely hit the power supply in your set---time for a tech or shop to open it---I suspect they will find the standby or main power supply is damaged or now bad.

Telly on but no sound orpicture


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL2100 you can find it here http://www.discount-merchant.com/Sony-XL-2100U-TV-Lamp-p/sony_xl-2100u_replacement_lamp.htm?Click=48173 .Have a blessed one!

HDMI conneection wont override tv picture


I am a sky engineer (not a subby)
the reason this does not come on straight away is because a Scart lead send power upto your telly when it is turned on. Telling the telly that this is what you want.
Unfortunately HDMI does not send power upto the telly. There are ways around this. ON Samsung, Panasonic and Lg tellys you can go into a secret menu and apply something called HOTEL MODE this allows you to change the av input so it would automatically come on your hdmi 1,2,3, etc

In your case follow my instructions below

go to the hdmi you are using for your Hd

on the sky remote
Press SELECT and GREEN until LED flashes twice.
Press HELP then SELECT and the LED will flash Twice. what this mean is when you press your Sky button, tv guide, services or interactive button to turn the sky on this will automatically change your av/source on your telly to the sky HD for you

You owe me a pint
Have a good one

Code for 32 in lg tv to work with sky control


TV
RED + SELECT
TV
0056

try the power button if this switches off your telly press select to save the code if not repeat TV and then Power until it does... remember to press select once it knocks your telly into standby.

if you have not joy with this then you are going to have to get a newer sky remote. if you take the battery cover off the back of the remote you will see a sticker on there saying REV 4,6,8 the higher the number the newer the remote. then do the process again.

0056 is the manufacturers code for LG
