The Optical Block is causing the problem. It has been a common problem and Sony may still have a recall on it. You can check it a 1800-222-sony. If it is not still covered, I would expect to spend 800.00 to 900.00 for the assembly plus 250.00 labor for a professional to replace it.
I hope this helps,

You can purchase the lamp yourself and replace it yourself. The lamp is built to fail after about 3-5 years depending on how often you watch it. There are step by step directions in your user's manual. If you have lost or misplaced it, you can download it for free in PDF format on the LG website. The lamp usually are around $200.

Blue spot on screen


there are light filters at each of the 3 lcd panels in the optical engine with a coating on them that determine the color. one of them (most likely the blue) is burnt from the heat and needs replacement. it could also be the fly-eye lens (whick evenly distribute the light) has burned as well. either way, it's very involved to replace, if you can get the parts. it's easier to have it sent in to get repaired.

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.
