I purchased modle number un55mu6300fxza and have only had it for 2 years with mild use. However i seem to be haveing an issue like numerous others.
So the standby light will come on, showing power is getting to the tv. When I turn on manuelly the standby light goes out and backlight turns on but that is as far as it gets!!!!! Then standby light comes back on and the tv just keeps repeating that cycle until I pull the plug. I have read numerous other post about exactly the same issue. When will you recall these models? I have only had the tv for 2 years and mildly use it.
