[Resolved]  LG 21sa1rg3t8 / 2009 — before 1 yr TV screen vanished, Want replacement

I purchased LG Flat screen TV 21SA1RG from Vijay sales Andheri (w), SV Road. Dated 24th Dec.2009.

Few Days back on 8th Nov.2010 the screen of TV is become eclipse in shape and TV automatically switched off after mins. I already launched complaint to LG customer care on 8th Nov.2010 and request ID is C10B0846290. After 2days one technician come to attend the complaint and he did not solve the problem and went out by instructed that do not switched on the TV the work is not complete, you do register complaint again at LG CC. I again launched complained on 20th Nov.2010 and request ID is C10B2010433. Then on 22nd their same technician come and he work for just 5 mins and said that the coil is not working I have to bring coil and he went back. Both the time he came very late evening and work for 5-15 mins.
Now the TV set is still not working I already talk with Vijay sales they said within 3 days they will send technician and sort out problem.
I wish replacement of my TV set from LG because within warranty period this set cause big problem related with screen. and even if it sort out no guaranty of working properly in future after warranty I have to pay for all this part.
So I request you to help me out in this matter.
