If it looks like a cloud of colour, the optical block needs replacing. It is the heart of the LCD. We had ours replaced twice, under warranty.

Blue patch on side of screen


This is your Optics Block failing. One of the filters creating this issue. If you don't have warranty (call SONY customer service to check it out) - watch it like it is until you get new TV. It is very expensive repair.

this happens because of panel conditioning. as the panel ages it requires different voltages to produce the picture.it takes about 1000 hrs before it has conditioned. it is a simple adjustment a tech can do for you. when this adjustment is made no other adjustment will be needed for this problem.

Yellow brush marking on Screen


Your problem is with the blue color,maybe some dirt is sitting on the face of the blue crt and is being projected bigger to the screen,you should try cleaning the face of all 3 tubes,if you familiar with tv service this should help,be careful when removing the back and make sure the set is unplug when you do the cleaning.Let us know how it goes.
