When i was in college for electrical/electronics we fixed a tvs in lab that had the same problem
the same problem can be caused by holding a permanent magnet to the screen of the tv this causes the problem
the fix of the problem is to build/buy an electromagnet that u can plug into your wall outlet, then wave the electromagnet around the screen say 6 inches away from the screen making sure demagnetize the affected areas. u can buy an elctromagnet that opperates on 120v ac electricity at radio shack. do not use a DC electromagnet that will make the problem worse.
u can find out how to build an electromagnet off of the internet by googleing "how stuff works"

    Check out the class action lawsuits for defective Sony TV. Many models over the past 8 years with the same problem. Do some google search about your model and other similar Sony models with the blue spot and blue smudges on the left side of the screen and at the bottom. Sony is giving free TV's and/or greatly reduced prices for a new model. But hurry as many of the class action lawsuits have already expired.

How do i replace a bulb for kf-50sx300u

There are two big screws at lower corners of tv at rear side, open them with coin then pull out lower front panel, in middle you will see lamp door, open its screw with coin to see lamp housing, lose its two screws with hex-key and pull out old lamp. Slide in new lamp and put things in reverse order.
Lamp replacement procedure is written in user manual and explained with pictures, check page-28 to have better idea.
Click Sony Support link to download user manual free copy of KF-50SX300U if it is required.
Hope these info will help you.

Blue hue accross bottom of screen - Sony KF-50WE610

You can try doing this, turn on the Tv and select the service menu, if that tint also shows on the menu, it's most probable to be your DMD board, but if it doesn't it might be the video board..

Kf-42610 blue hue and blue dots on screen

Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )
