The problem of your tv is the convergence. Projection tv set has a 3 colors red,blue and green this 3 colors must be properly lined up to look the video normal. When this 3 colors is not properly aligned the video will produce a double image of color or like a 3d or wavy. In order to fix this problem you should adjust it in the menu program of your tv you should move any of the colors to up or down, left or right if you cannot align the 3 colors the problem is the convergence ic it must be replace. To locate the convergence ic you should remove the back cover of your tv but be sure to unplug your tv, you will see this ic attached in a large aluminum plate it has a marking of stk--- and followed by a numbers. or you could contact a service technician do do it for you and save you from stress. Good day and best regards.
You have a bad convergence board. Replace two of the STK 392-040 ICs. And check all the resistors that are next to these ICs. Rplace the resistors as neccessary. This will repair your TV. Thanks for asking...sorry it took so long to find you!
It sounds like one of the convergence Ic chips is bad---you will need to locate and replace both of them and look for any damaged parts around them; there usually are two pico fuses in this area, one for each IC. The fuses do not look like glass fuses--they usually are green or orange in color and will have the amperage marked on them and on the top of the circuit board.
