My Sony TV Model KDL-40EX520 digital colour had a discoloration problem on LCD panel is problem a major one and factory defect. Just bought and used more than a year. How to find for replacement if no

I don't have a listing for your model, but it is not unusual for the panel to cost more than a replacement set. As another example, the replacement tube (CRT) for a 27" Sony set can easily be $700. This was when these sets were being sold for $350!! Parts is where these companies rake in big profits. Don't blame the servicer for this one.

Sorry about the bad news.

You are going to find it is a LCD panel problem. I am sure that they will take care of you. But also realize that this could have happen to any brand of LCD panel and you will probably not have any other panel issues once it is fixed.
I feel your pain,

This can be the panel itself, and or the matrix decoder/driver boards. The cost of this type of repair can approach the cost of a new set. From your description, I am thinking it is the panel itself that has failed.

Parts for your set are from Sony only because there is no third party manufacturing for these types of parts and assemblies.

Usually, when these types of sets become defective they are usually not worth servicing. During warranty the manufactures generally give a new set to the client, or they give a re-built set which has been built up using parts and modules from other sets that came back for service and had different types of problems.

If you know a tech is is good at servicing these types of set, maybe he can find a number of scrapper set of the same model to take parts from. You just have to hope the ones he finds have the same types of fault.

Sony is replacing LCD Panels at no charge until October 31 2012. The KDL46XBR4 and KDL46XBR5. If you paid to repair they'll pay you the cash back you paid to repair it.

That symptom may cause by the main board or t-con board, I suggest you do software up grade first.
