What you need is to have the lamp timer reset. To do so, perform the following;

You will need two hands.

With the remote, press and hold down the "mute" button.

Simultaneously press and hold down the "enter" button on the front of the TV.

After about 5 seconds, a box will appear that shows the total number of hours on the lamp. To reset these hours, press the right arrow button on the remote. After doing so, another box will appear with a confirmation question and an icon for which button on the remote to press to reset the lamp hours.

follow this steps and fix it. God bless you

  • Reset component settings. Usually, the problems you encounter with a projection TV may be resolved through the resetting to its factory settings. If you experience inaccuracies in the color, reset the television's PerfectTint/PerfectColor capabilities. Simply press the Menu tab and then highlight "Perfect Color" using your right key arrow. After this, press "Enter" and then "Reset" in order to reset to factory settings. If you have audio / video problems (VCR or DVD player), simply press "Menu" and highlight the "Reset" option.
Reset television controls. In case you cannot fix your TV via its component settings, there are other ways of resetting. Just select "Menu", key in "1, 2, 3", and then press "Enter." In doing this, the TV's manufacturer's specifications will all be restored. If your TV's power system does not function, you should perform a complete system reset. You can do this by clicking on Reset System button located at the TV's control panel. Your television will be turned off and then a green light (LED) will quickly flash for approximately one minute. Once the light has stopped flashing, your TV should immediately turn on.

I have read another solution which may indicate the light engine has failed and will likely need replacing. The cost is quite expensive. $1500 range and apparently the part is no longer available from LG. Best you might do is get an estimate to repair just to be sure.

so the one first is an LG model ballast but the one in the tv is a phillips one, strange.. can you give me the bord number power side... it is always best to replace old number so the damaged numer one should be the number you use. LG, Philips etc use different part to make the same tv model. e.g one can be made in twain and the other from china. both the same case do the same things but have completely different parts in side. Looking at the parts on line they don't have the same connections or the same voltage so would be a bad idea to try and put the new one in with the wrong number.

Hi richgpilot,
May I know how many blinks does the led light before it goes to standby mode. It will help diagnose where the exact fault came from.

The site I work for has the same manual as you most likely as its the factory service manual. So we dont have the schematic either

That issue is caused by the convergence chips going bad. They both need to be replaced as well as some of the resistor may be bad. To fix the board it usually runs around 300 to 350 dollers. You an order these parts yourself on the net from several places and they have instructions for the replacement of the boards or the convergence chips.

I suspect the replacement lamp you first put in. It shouldn't be shutting off like that. I dont know if the replacement ballast was correct, but I wouldnt buy parts off of Ebay unless I knew it was an oem part.

put the old ballast back in and see if it works intermittently again. That should answer the compatibility question.

I dont know if those parts are interchangable or not. You might try a little investigating at wehaveparts.com

WARNING: Before doing any work on your television, make sure that it is unplugged and has not been in operation for more than 1 hour to allow the lamp to cool down. Use extra caution when working on a power supply, like the ballast in this topic. Even when the television is unplugged, do not touch the electronics within the device. Capacitors can maintain a charge and cause a shock.

What is the ballast

An electronic ballast is a device that provides steady electical current for the starting up and operation of a lamp.

When to Replace the Ballast

If your lamp is not starting up and you are confident that the lamp is good (e.g., it is new), it could be a faulty ballast.

Where to Buy


I have had good experience with Partstore.com in getting replacement parts for my electronics repair projects.

How to Replace the Ballast

Compared to other parts in the LG television, the ballast is relatively easy to access.

Remove the back panel from the television.

Remove the lamp.

Unscrew the cover sensor switch on the right side. The wire going to this switch is short and will prevent the insides of the television from sliding out.

Locate the ballast. It is on the right side (facing the back of the set), mounted on top of the large cooling fan. The ballast has 4 screws holding it in place, one on each corner of the green circuit board. It also has a red two-wire power cable that goes to the lamp connector not far away. Take careful note of the position of the cables and how the plug is connected.

Unscrew the lamp connector. It is easier to access the screws when it is in its normal position and before the insides of the television set are loosened. There are two small brass screws that must be removed.
Here is the connector when attached.

After removing the screws, the connector will come free:

Remove the screws holding in the 'guts' of the television. This will loosen the entire inside of the television allowing you to slide it out. You may find it useful to follow steps 1-6 on this guide to replacing the LG color wheel. Accessing the color wheel requires that the insides come out fully, so some wires need to be disconnected. To access the ballast, you should not need to remove any wires. Stop at that point in the color wheel instructions.

Carefully slide out the right side of the inside unit. Unless you removed the screws that hold the left and right panels together, the entire unit will move as one piece. At first, you'll have to ease out the top and bottom center of the unit as it is a snug fit. Once they are free, you can slide out the right side just enough to access the ballast. You should not need to remove any cables to get the insides out enough to work on the ballast.

Use caution to not touch the electronics. This is a power supply and the capacitors can hold a charge even when the television is unplugged. Unscrew the ballast circuit board and remove it. The power cables should already be free. Store the ballast in a safe location.

Install the new ballast in place of the old one. Snake the red power cables through the holders. Like on the removal, it may be easier to screw in the lamp connector plug screws after the insides of the set are secured back in place.

Put the insides of the television back in on its track and screw it in. Be sure not to put any screws in to holes that are to be used in fastening the back panel. It helps to compare the back panel to the back of the set to determine which screws are on the inside vs. the outside.

Reattach the cover sensor switch from step 3.

If you haven't done so already, reattach the plug at the end of the red cables. There may be a plastic holder that you need to remove from the old ballast that the screws go into. The plug fits into this piece a bit like a puzzle, so it may take a little wiggling to get it out. Be careful with this. I've heard from at least one person that this plastic piece is brittle and can break.

Install the lamp.

Put the back cover back on and fasten with screws (14 screws).

Plug in the television, say a prayer, and turn it on.

Good luck.
