Question about Televison & Video
Hi I would like to know if u guys can help me with a problem on my SONY KF-50SX300U 2 weeks ago start on tv screen 1 small blue spot know after 3 weeks is more than 10 and would like to know if u guys can help me with tis problem many thanks. email@example.com
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"
