it was purchased as a replacement lamp from samsung
Thanks for the reply.
I have to tell you that ALL of the symptoms you have here- picture for a few seconds, 3 LEDs on the set blink, and you're left with sound but no picture ALL point to textbook lamp failure.
It's very rare for the lamp to shatter, or blow completely as they are not like regular lamps. They are the same type of construction as florescent light bulbs, in that they are charged with a gas, and once the gas leaks, they will light for a brief period of time then go out. This means that the lamp is unstable and needs to be changed out.
The solution here is to replace the lamp, your ballast is fine as it sparks the lamp up with no problem, and there's no symptoms that would cause us to look elsewhere. You can purchase the replacement lamp for your set at the link below, or from Samsung again if you'd like:

i have another bulb....which already has about 6 mo. use on it when i changed it out (i can't remember why i did that, but i still have the bulb)....i will put it in and see if that fixes the problem....if it does not fix the problem, what should i do
i will try the other bulb...but i will rate you now too
i put the other bulb in and the tv pic and sound came on normally....am now just waiting to see if it stays on
its been 7 minutes and it's still on....so i'm thinking that was the problem. excellent service aric...can you send me another rating thing or can i use the one you sent in this thread
