If some areas of the screen or all of it in the kdf-70xbr950 are off color in this fashion it is likely a bad Optical Light engine which Sony is replacing even if the set is out of warranty for free.

Sony model kdf-70xbr950 , screen has blue streaks and blue dots. app. repair cost ,tv is 7 years old


Hi,what you are experimenting it's a faulty light engine problem,this is a common failure on Sony tvs.What's happening Is that your tv carries 3 chips blue,green and red, those chips are in charge of creating the colors on your tv .When these chips start to melt you will get color discoloration.Repair cost will be very highly around $400-$600 The part you need it's called the light engine or optical block ,some people are getting sony to repair their tv at no cost,I suggest to contact them to see if you qualify.God bless you!

This is a Light Engine problem. Call a good TV Tech and explain the problem. These can be rebuilt for around $450. New ones are $800 to $1200.

Blue shadow


You have a bad light engine or in Sony TV sets, it is called an Optic Unit Block Assembly. This is a very expensive part and should not be attempted to be replaced by a novice. Call an authorized Sony repair place to have this repaired. Good Luck
