[Resolved]  Sansui TV 21 Inch Hard Rock — repetitive problem of EST

I am having a sansui CTV 21 inch HARD ROCK purchased in 2003
from last two and half years it giving problem in picture quality.Last year i put a complaint in sansui then engineer came from sanui and changed the EST and take mone for the same.this year also the same problem arose again i again put a complaint #400sa07224815 then engineer came have same reply that EST was down and told this problem will arose every year again & again.
I literally fed up with this product and service of this company
and still if there is no solution of this problem i never suggest anyone to buy sansui product.
