I have bought sony bravia tv klvv40a10 and after guarrantee expirey it started to show patches of green colour.
I have contacted the sony dealers in kuwait they said it needs circuit board which cost around $600
i have asked them to returned the tv.
one day i opened the cover and cleaned by hoover. closed the the cover and it started working fine.
After one week it started again.
please help me sort out this problem if you know
