LG rear projection colours out of alignment

I have an LG rear projection TV: RT-44NA11T

The red and blue colours are out of alignment, the red being the most prominent, but it is not consistent across the screen. It is out on the right on the right hand side of the screen, OK in the middle and out on the left on the left hand side. Convergence menu does not rectify this problem. Is this likely to be a lamp issue, some sort of focus problem or other? Can it be fixed by the user?

Thanks in advance

SOURCE: LG rear projection colours out of alignment

I have a similar problem with an LG (except my red is the one that is fine) and was able to talk to a tech in some detail about it. The tech prefaced by saying that he had done a hundred or so of these with exactly the same issue. This is very common and the life span of rear projection televisions is not great. Having said that, plasmas and LCDs are also limited in life span mostly due to modern high performance gaming machines which shorten the lifespan of monitors both plasma and LCD alike.

From what I have gathered, this is not a problem that you can easliy sort out. (Of course they would say that though) It involves replacing the digital board which means soldering followed by aligning the lamps which requires quote a lot of expertise.

The part itself apparently costs around $200 Australian and the labour will vary for the cost of the technician but I was quoted that the labour was about the same cost as the part.

Not sure if I would call this solved but I hope it has been at least a little helpful.

Picture is OK, but colors are off and there is a blue star background that shows on dark colors.


Hello, With most rear projections there is usually an alignment to do with the set up with your TV. This is so the red, blue and green projectors align together to give the correct colouring. This sounds to me what may be causing the outlining of the blue. This can also make it seem off colour. Look in the set up menu of the tv and see if you can find this alignment feature. Usually a cross will appear and you move a blue, red, and green cross with the arrows on your remote to align over the original white one. If this does not work, it may also mean that one of your projectors, that is the red, blue or green one may be failing causing the off colouring. Hopefully this alignment may fix it for you.

My sony grand wega gives a blue shade on the black background which is the problem


HI, Check the menu set up of the TV. There should be an alignment feature that aligns the blue, red, and green colour projectors. If the blue is out of alignment that is likely why you can see it on the dark backgrounds. The set up normally puts a white cross on the screen and you select each of these colours and then move the cross over the white on with the arrows on your remote. Once all are aligned correctly you shouldn't be able to distinguish between different colours and hopefully this should get rid of your blue shade.
