How old is your lamp? This isn't likely the problem, but they do tend to go out over time. This could also be related to the colorwheel motor going out or the DMD board sending a faulty signal. I would suspect this to be about a 200-300 repair. The diagnosis process is going to be hit and miss. How attached to the tv are you? :)

Hi,do you hear buzzing,whirling or high pitch sounds? if you do it could be an issue with the color wheel If the TV have the infamous blinking lights problem and you're replaced your lamp without success, it's most likely a problem with your color wheel. The Samsung color wheels spin anywhere from 6,000 to 15,000 revolutions per minute (RPM’s)--It is one of the few consumable parts in your Samsung TV. The average life expectancy from our data logging shows the Samsung color wheels are fairly reliable with a MEAN average of 5-8 years .It could also be the DMD board this is how it works:http://electronics.howstuffworks.com/dlp1.htm One simple way to test if it is the DMD board it's to display thew menu,if menu is also affected that for sure what it is.God bless you!
