I have been emailing and complaining about a SAMSUNG LED TV 32inch purchased from Vijay sales – infiniti branch andheri (west) mumbai vide invoice no.27-IN12-10SIAO-234 dated 18-12-2010. for Rs. 42,500/-

i would like to bring to your notice that the trouble I am facing regularly in the TV from Feb-2011.
1) TV goes blackout complete for few minute
2) TV”s sound goes off for few minutes and come back
the above problems was regular and on &ampoff for several month till jul-2011, when time of blackout/sound started taking longer time., few occassion mecanic visited and charges me Rs.170 for inspection (invoice no. SVCMUM 43886 dated 10/07/2011) wihtout rectifing the problems stating let this problems continue till the TV stop working completely.

Till Dec-2011 I managed and use the TV with letgo as per mecanics instruction and one day in Dec-2011, TV has stopped working your mecanic visited and replaced SMPS and charges me Rs. 2439.00 (invoice no.061940 dated 10/12/2012)
Immediately after changing SMPS in the same month, on TV screen some horizontal lines started appearing and images/picture showing blur colours,

This time Your engineer has visited twice and try to fix the problem with changing the TICON/LOGIC BOARD by quoting Rs. 7900/- and tryed to change but it doest help and problem remain, now he has suggested to change the PANEL of Rs.18,837/- for smooth function of TV.

my question to you is how many times i need to repair this TV and how much and how long i have to spend/bear the repairing cost on this TV ???
How can this TV has so many problems in all area (sound, colour, picture) ?? Is this TV is defective piece ???
Do you expect SAMSUNG customers to spend 50-80 of cost on maintence after a year ??
I am regular user of SAMSUNG product refregigarator/washing machine & AC and i have trust on samsung product and this will be my last chance to contunue trusting SAMSUNG….. if i dont get satisfactor solutions to my complaints.
