It seems like the blue colors are seperating from the rest when the TV is turned on. It goes away in 1-4 minutes. It just starte4 days ago and does not happen each time, but is getting more frequent. Thsi TV weighs 225 pounds and is downstairs, so hopefully I can repair it here. I am well versed at schematics and soldering as I repaired military aircraft for many years and now am a computer tech.
You will need to change the convergency STKs to restore the distorted colors. Check the low value resistors, fuse esistors that are connected to the ICs leads.
Those parts are mounted on a heatsink, they have normally 18 to 20 leads depending on their numbers.
Hope this helps.

Can you call up the settings menu? Check to see if the ANT-1, DVD, and other ports are properly activated. You may need to re-scan for channels and to activate the HDMI ports for your other devices. Regards.
The other stuff is probably the Engine as well. Before going any further, have them replace it again and see if the other problems show up. I am willing to bet they wont. These Engines are mostly refurbished units and if they originally had intermittent problems on the Digital Board that comes mounted on the Engine it would get passed on to you.
I would not wait before having it replaced and I would Call LG first to let them know you got a dud replacement Engine. Let me know how it comes out.
I am assuming you mean bulbs. Typically the bulbs do not just move out of place on there own. Did the tv take a sharp impact or did some one hit the tv hard enough to move it. The bulbs are held in place with plastic sleeves that are typically held in place with 6 to 10 screws depending on the model. Your local repair shop may be able to assist you in renting the allignment tools for your bulbs. Typically the convergence chip goes and it gives the TV the appearance of the bulbs slipping and makes the tv look like the colors have seperated. One of the colors seems to have shifted to one side and doesn't line up with the rest of the picture. So check with your local dealer or write to the company and see ig your convergence chip is available and if you can rent the allignment tool.
Have you used the color convergence settings on your TV?When the settings are off you will get this effect sometimes if the TV was jarred pretty hard it goes out of alignment.There should be a setting on your menu.If that doesn't help it may need re aligned by a repairman.
Blue convergence IC is bad....change both,,,original number
Stk392-110 replace with upgrade Stk394-160E Hitachi part
# CZ 01341 ....also check B+ feed resistors for over-heating
