LG Electronics — led tv's having white spot issue

Address:

Bangalore, Karnataka, 560103

I had purchased two led tvs one of 32 inch and other of 42 inch in 2015. Last year the 32 inch developer white spots on the screen. I repaired it through lg service team paying 3500. Now again my 42 inch tv is having the same issue and service centre guys are asking 7500 to repair. This is like looting people after buying so expensive tvs. I googled and found that its a known issue with lg and many people are having it. Requesting someone to intefere and help me.
