Blue and yellow shadows

The model indicated uses what is called a Optical Light Engine, it is a very expensive part and likely is your problem---not much else will cause this trouble.

Let me know if you have questions.

you need to auto focus it, if this doesn't work then you need convergence chips

Replace the Blue convergence IC, But you should consider replacing both of them, because if one has failed then the other is likely to sooner or later. They are large Black IC's mounted on a Metel Heatsink. I believe on this model the board is in the middle of the unit. Before you replace check the solder connection on the Ic's first you might just have a few cold solder joints, if not then replace both IC's

You will not be able to solve this yourself. It needs the convergence IC's replaced which is a big job.

Did you ever get the solution to this? I'm having the same problem on my 65 incher.

how old is the tv ??
if this tv is older than 5 years it may need to refill the liquid on the proyection bulbs and/or could have contaminats in the fluid causing the ghost and to fix that you will need a professional person to do it

convergance ic bad

It's a hardware malfunction. It can't finish the magic focus cuz one of the IC is burned. Need to be replaced and to check the resistors.

Needs convergence circuit repair = replace convergence IC's,
then activate Magic Focus...............need step by step?......T.

my suggestion would be...to replace the focus block..john
