The warranty is usually 1 or 2 years so you wrote 1 year so check that warranty and extend it. If it is LCD bruising, well that's on the web and not covered by warranty after that much time.
I've been using this LG 42LB5510 for one year.. Suddenly this morning, when i was watching tv ( its only been 15 mins since it switched it on ) i encountered with a strange sound from the television and suddenly i can see 7 bright medium sized white spots ( circles ) on my television screen.. i switched it off and i again turned it on but it made no use.. those spots are slightly visible when tv produces a dark picture and they are really bright when tv produces a light or bright picture ( like white background ) .. The fact is, all the spots are symmetrical.. they are aligned in a column fashion.. 3 in the first column and 4 in the next adjacent column..
What has happened to my TV..what should i do now to solve this issue? Please do reply and thanks in advance
