We have a Samsung LN40A550 LCD television that we bought about 2 and 1/2 years ago. Last night it started making this high pitched alarm or buzzing noise that is so loud you have to jump to unplug the t.v. before your ears get damaged. There was green vertical lines running across the picture but now there is nothing but a blackness. Has anyone else had this problem and is this connected to bad capacitors? We have a repairman that Samsung has called to come out and look at our televison but if it is not something that is due to bad capicators then we are responsible for the bill. Wanting to get any information I can before this. Paid alot of money for the t.v. and very disappointed to say the least. Any help would be very appreciated. I'm not very technically literate so could use some guidance. Thanks so much! Ellen
I had the exact same problem...did you ever figure out what happened, if so I would love to know??
