Hi adi.. I know ur using the same exact tv as mine samsung 55 inch led tv D7000. Do you have similar problem? 1 month after installation, tv broke down, keep auto on & off... kpkb, bang table, samsung replace a new one for me.. less than 2 weeks, same thing happen. Called them juz nw, they say will replace panel tomorrow. According to them is the LED panel spoil..i dunno isit coz i misuse or juz the fcukin product is a big lemon. TV lightly use, weekday evening - 1 to 2 hours, wkends - 3-4hours per day. Really dunno why. Im so getting extended warranty.
