SOURCE: tv turns self off when turned on
Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.

Manual says you need to replace the lamp:
When do I need to replace it?
• It should be replaced when the screen becomes darker, less clear or when all three LEDs on the front (STAND BY/TEMP, LAMP, and
TIMER) are flashing

You will have a couple of problems here: This model may use 2 completely different DMD boards---need to get the right one.
Also, DMD is usually about 400 dollars and entire light engine with a new DMD is about 450-500-----they really don't want to sell them.
If you were to replace the DMD you would have to get at it (it is on the back of the optical engine and usually you have to remove another unit bolted up behind it, remove a fan in back of it and then release 3 long recessed bolts to take it out.
I did these and they are not easy---when you install the new DMD you have to POSITION THE DMD WITH THE SET ON---it will center the picture up/down and left right--moving it up slightly moves the picture down-----every action is opposite of what direction you move it.
Presuming you get it centered you have to tighten the three bolts slowly---as you tighten they tend to move the picture in some direction.
I think you get the idea---the DMD is not a "easy" part to properly replace.
The shop I work for---we have tossed several of these sets to be recycled as the cost of the part is more than the set is worth used.
If this information told you something you did not know, rate this solution as I do this here for free.
You may also want to contact SAMSUNG as there have been some programs where they will cover the replacement because so many failed and lawsuits were started etc.
REGARDS, SD TECH
