Question about Samsung LN52A550 LCD TV
This model has had problems with electrolytic capacitors on the power supply which will cause your problem. I've fixed several of them by replacing these caps. The caps will most likely be bulged or mushroomed on top if they are bad. This is the most common problem that I have found on this model.
If it is in warranty, then I would just contact Samsung and they will send a tech out and he will fix it for you at no cost.
