We have blue botches on the screen along with blue dots which are spreading. It is a WEGA KF-42WE620- we have had it for 4 years. Do you have any idea of what is causing this?

Hi

Yes, your optical block is faulty. To save you time I though I would direct you to a dedicated website regarding this problem.

Your model might not be the same as the models listed, but believe me you have the same problem.

Near the bottom edge of the screen on my Wega KF-50WE 610 has appeared a ''blue haze'' that appears after the TV has warmed up. It started a few days ago as ''fuzzy blue dots'' about the size of silver...


This was caused by a defect in the optical block of the TV. It will only get worse with time and the only way to fix it is to replace the whole optical block which is very expensive (over $1000 usually) and time consuming (you need to take the whole TV apart). However, since it was a defect, there was a class action lawsuit that caused Sony to extended the warranties for certain models on the optical block for parts and labor. Call Sony to see if your model was one of the ones they extended the warranty for.

Could be the problem they have been covering it under a recall of sorts. $1250 for the optical block and they are only doing it until the end of the year so don't waste any time
