Question about Samsung Projection Televisions
That usually means a problem in the start up or deflection circuits. Diode, Horizontal ouput or driver transformer. What Chassis is this set, and I will be ableto give you some better information. Rca , GE and phillips need to be diagnosedwith the chassis number. Let me know the chassis.

SOURCE: TV will not turn on
There are a few reasons that this could be happening first one is maybe the lamp died on you, Afraid there is no way to test this other than replacing the lamp. The second problem may be 5 capacitors on the power supply that hold the 12 volt line low and do not allow the light engine to start properly.
First thing you have to do is listen to how it trys to start, It should sound like this, first when you hit the power switch there may be a click then within five seconds the fans then a few seconds more you may here a sparking noise, if all this is happening then you most likely just have a bad lamp

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to.
I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.
