This is blue CRT problem in tv as it is rear projection tv that has three CRTs red-green-blue inside to project color picture on front screen. Blue CRT (tube) will be replaced to fix the issue and it is job of Pro because lots of adjustments are required after replacement of tube. Local tv repair shop will help you for that. Thanks
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.
You will have to take the front cover off, usually 3-6 screws holding from the back, when it does come off there will be wires to the control panel attached still. you will also have another panel to undo. after that there will be a block with 3 focus controls and 3 screen controls marked b g and r for the three colors. The blue screen control is the one you are looking for, be very careful the slightesr turn has huge response including shuting the tv off when you turn it the wrong direction to far
Does this happen when you play a dvd? if so your RED, GRENN, and BLUE lenses in the tv may be out of alingment. First try pulling the power on the tv (make sure the tv is turned off first) wait about 2 min. then plug it back in. If this stil continues, then what i said earlier may be the case and sorry to say unless you have a warranty you will be better off to buy a new tv. Now days it costs more to repair a tv than to buy a new one. And it could very well be the receiver
Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.
