TV shows large red spot in middle of tv when dark show are on, you can see it more. Now blue spots on upper right side too. Spend way to much on this tv to have these kinds of problems only after 3 yrs.
Go to the convergence menu and see if you can see a clear Blue cross when you try to do a convergence. If the blue looks only like a blob of blue. then the coolant in the blue tube needs replacing. if the blue cross appears as a cross the convergence ICs are probaly weak. I would guess its the coolant thouh that model has a tendancy to trow a blue streak when the coolant is even a little cloudy. let me know if you need more assistance.
