Re: Blue-ish colour develops after an hour LG 42PX5D
There are voltages in the power supply that need to be very closely matched to the sticker that is on the back of the plasma display panel. If some of the voltages especially the VSCAN goes too high or too low then abnormalities such as discolorzation can happen. Changing the direction only affects direct view CRT's only. Plasmas are only affected by elevation and thats usually when you live 5000 feet or more above sea level. I would have a technician check the voltages once the panel has warmed up for 20 min or so and see if they are correct. Good luck.

If you have a Sony rear projection LCD TV then you have a failing optics block. LCD TV's are not affected by external magnets like CRT TV's were. The optics block issue will only get worse and needs to be repaired by a technician.
the lcd panels in the optics block are going bad, getting dirty etc., the block needs replacing and will cost upwards of $750.00 total. google sony optics for your model for warranty extension possibilities.
The cost I don't know, but this can be fixed. I'd say shop around a bit. Make sure the repair person is certified for your TV's manufacturer.
There are generally 3 lamps in projection T.V.'s, Red, Green, and Blue. They have to be aligned for the TV to project a clear picture. A credible TV repairman should be able to fix it. Depending on if it's new enough to be under warranty they may cover it as well. Really the only reason to get rid of it is if you want to get a new TV anyway. Depends on the cost of having the lamps aligned.
Inside of the tube assembly, there is a cooling liquid. This could be a job to change, and then re-adjust everything. It is also possible that on top of this, there are problems with the convergence and bias control circuits.
Typical repairs can run in the area of about $400 to about $800 depending on the amount of work and type of parts required.
Personaly, I would go out and get a good Plasma or LCD TV at this point!
I believe i have the same problem myself. When my TV is on any of the Component Inputs without my DVD player turned on i usually get the normal green screen. But now that is a dip in the green at the top of the screen from the top left to almost the top right and black pushing down on the dip. Almost like a green curtain was sagging at the top and you can see the black behind it. It does this on every input and distorts every picture you see. The distorted picture has all the green slightly off from where the rest of the picture is and where the dip at the top of the screen is there is somtimes purple instead of black.
I know the basics of how the picture gets onto the screen and its my guess that the Green "gun" for lack of a better term and somhow come loose, or been missaligned to a great extent. I would love to find an answer to this problem, and anyones best guess as to how much a repair man will charge, just so i know the ballpark.
