Question about Samsung DLP HL-P5663W 56" TV
Is this a symptom of a problem that will get worse. Could it be a timer that is set to turn off the lamp, in order to extend it's life? Does it sound as though the lamp is going out? I am relatively techy. How difficult is it to replace the lamp myself?
No such thing as a timer on the lamp system, but it does have a thermal fuse.. But it would only take one overheating and the set would not come back to life on its own..
The one marked problem this particular unit has, that I've seen about a half dozen times or so, is faulty color wheels. Even though there is no video or color distortion the motor in the color wheel can begin to drag cause an excessive load in that assembly and eventually to the symptom you're describing. But it could equally be something else in the system loading down the power supply and causing the shutdown.. It's difficult to say without some testing.
You say you're "techy"... Do you own a scope, logic probe and an ESR meter? If not, better leave this one to the techs. If you do I have the service manual and could Pando it over if you'ld like to trace test the SMPS and wheel.
FYI: there is a new wheel assembly for that unit that replaces the type that unit was assembled with at the factory - under Samsung p/n# Bp96-00674a.
Hope this helps!
