LG 42LG30 42 in. LCD HDTV - Page 8 - Answered Questions & Fixed issues

Cable boxes can latch up from time to time. It can be from a momentary poer loss or poor ventilation or any number of things. Try pulling the plug on your cable box for about 15 seconds, then plug it back in. Wait for it to reboot. If this does not correct the problem, contact your cable provider and ask them to send a reset signal to your box. I hope this was helpful, best wishes.

this is definately tuner board they not hard to get try ebay either look for the board model or buy a broken screen tv and then use the board and sell the bits seperate to recover money back from the tuner :) hope this was useful

On the bottom of your screen should be a volumne button. Press it once and then the + button beside it. Hope this helps!

sounds like the power supply. In most cases its nothing to get to worried about. Do you have a surge protecter or a power conditioner hooked up to it?? this could help. Try to unplug it overnight and see if it will stop.

Comment back to let let me know how it goes or to get any information on power supplys or power conditioners.

Sky remote code for LG LH3000 is 0206. This works for the 37" and the 42" and probably for a plethora of other sizes.

It's not your TV, it's your cable box. 2.4.6-19 is the HDTV program. Just turn the cable box off for 10 seconds.

To use sky+ remote control with LG 42LH3000 you must have a rev ver8 remote controller.
The codes are stored in a database of the Sky remote. If the old codes don't work
you may need to buy the latest Sky remote. Otherwise it is a matter of waiting for the
new Sky remote which may have the updated codes.
Note: LG Support supplied the following for Rev.8: 0206, 1293, 1665, 1174, 1176, 1219, 1280, 0857, 0851.

Version 1: August 1998
Version 2: December 1999
Version 4: May 2001 (Sky+ introduced)
Version 6: March 2004
Version 8: January 2006 (includes all current Sky+HD remote controls)

Hi, I have the exact same problem. I was wondering if you could tell me how you fixed it? Mine is only 2 hours old from the box

what version is your remote?

The TV is under a LG factory 1 year warranty.
Unless you bought a refurbished unit which has a 30 day warranty.
Contact LG @ 1 800 243-0000 for warranty repairs.
Be sure to have the...
Date of purchase
Model#
Serial#
And Product code.

The information is on the back of the TV or on a small white tag
on the side of the TV.

Contact LG @ 1800 243-0000 you may need a software upgrade depending on the serial # of the Tv.

very common problem on this model the mainboard eprom is failing not sold seperatly you wil have to replace the mainboard

need replaced main board

The exact model number is necessary to determine the exact parts your TV has. Some models has suffixes in their numbers to indicate they have some differences in their parts. For example, the 42LG30 is different from 42LG30DC, 42LG30-UD and so on. But generally, there are three parts that has a direct connection with the dimming and illumination of the screen. These are the T-CON board or LCD driver, backlight and inverter or ballast. The T-CON board is responsible in driving the LCD panel to produce the appropriate video or image. The inverter or ballast provides power to the backlights to illuminate the screen. If one of these fails, you will not be able to see any image or video on your screen.
The T-CON board is bad when there's a glow on your screen indicating that the backlight is on but there's no video or image. In short, the screen is blank.
If the screen is black, no glow, grab a torch and shine it on your screen. You will be able to see a faint image if the T-CON board is good. This indicates that the backlight is off. Either the inverter/ballast is dead or the backlight itself is busted. But usually it's the inverter/ballast that has failed. You can tell that the backlight is busted if the TV is old enough that the mercury vapor inside the tubes has depleted.
The T-CON board and the inverter or ballast are not serviceable and must be replaced completely if faulty. Replacing these boards can easily be done. Feel free to inform me if you find which of the above is the root of the problem to guide you in the fix.

To get the best quality of picture & certainly if you have High Definition then the HDMI connector is vital. If you are on normal sky transmission the a Scart from the sky box to the TV will be sufficient.

Let verify first to narrow down to where the problem can be. First, check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then 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 might want to see if you can get a Universal Remote that will program to the correct code to operate that tv. If that still doesn't work - it could be that the infrared receiver in the tv went bad? Then you'd be going to the repair shop to have it checked out. You might do that anyway and they can tell you for sure ... if your remote really went bad, or if the problem is in the tv.
