My Sony KDF-E50A10 50" TV has about a six inch horizontal area across the width of the screen that has a pink tint. This only ocurs on select channels. I am also getting a black and white dashed line appearing on the top of the screen which is only on a couple of channels.

Considering it is a 32 inch set and costs now under 300 dollars it may or may not be worth fixing.
To give an educated guess: either whatever it uses for an inverter board may be bad or damaged OR even the main board that processes all signal into or out to the screen may have either a bad connection(unlikely but possible) or be causing this.
A fatal issue could be something wrong in the screen unit (panel) itself.
I gather set is not under any warranty at this time.
after changing the lamp, I still had the same problem as you. I contacted sony and they offered me a brand new 40 inch bravia flat screen tv replacement...at no cost! If I chose a 46" or 55" there would be a charge between $325
This problem is caused by a defect in the optical block. It causes about 1 - 1.5" tint usually green, orange, or yellow at the top of the screen. The part is very expensive, retails around $600-800 usually. You cannot fix it without replacing the optical block. They did have an extended warranties for this particular issue because of a class action lawsuit on certain models. Call Sony to see if your model is one of the ones they extended the warranties.
We have aKDF-E42A10 for a bout 2 yearsnow and we now have 13 horizonal lines across the screen, they look like small square dotted lines across the entire screen from top to bottom. It be gan acouple of months ago as 2 of these lines that seemed to move up the screen. I called technical support and he made it sound like he never heard of the problem. I am very upset with sony right now. Anybody know how to fix the problem?ricedog
On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck
