SONY KDF-50E2010 HAS PINK STRIPE ACROSS TOP OF SCREEN

most equipment will not notice any difference between 50 and 60 hz power wise.

these are not designed to light to be directly on the screen--failing that being the issue the model indicated uses a lamp for the light source.

If another model and older set may require simple cleaning---confirm with comment button here that is is Sony and the model number is.....

mostly this type of problem come when there is some dust in side the optical unit you need to clean the dust.

no to be honest with you it looks like you have a optical block issue you need to replace this part check this link out hope this is helpful

sounds like bad light engine.

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.

Sony has extended the warranty on the optical block which you are experiencing a problem with until June 30 2010. Read about it here. http://www.agoraquest.com/display_alert.php?alert_id=17
