Address:

Chennai, Tamil Nadu, 600040

Sir, i have purchased lg 42 inch led television on may 2015. For past 2 years there was no complain or services met with the tv but after completion of the warranty period the problem started. This morning 9.08.17 there are two bright spots in the middle of the screen.
I called service and asked for estimation he said it will cost approximately 5000k-6000k. I have very much faith in your product and bought. But now it seems the bright dots and black dots appera in more televisions. Recently so what is the cause for this problem and seriously i can't bare 6000k for service. Plz take kind desecion as soon as possible
