Re: blue spots on my tv

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"

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..
