tThe diagnostic circuits is shutting your TV down. In most cases the set will shut it down immediately. Apparently your set hasn't shut completely down yet. When you turn your TV on the diagnostic circuits send a low voltage, low frequency signal through all the circuits and depending on how they come back whether the sets powers up to full power. If a problem is detected it will shut down to protect the other circuits. It sounds like you might have some capacitors going bad on your power board. A capacitor that is going bad would let it come on for a few seconds then the diagnostic circuits would see the capacitor getting further out of tolerance and shut the set down. If you are a DYS type person you might want to lay it flat of it;s face and remove the back. A bad capacitor will be bulged out on the top. are Replace capacitors with the exact uf value and if you can go above the rated voltage but never below., If this isn't the problem then it is probably the main board (the board where your cable hooks up to), There are other things that cab causes for this but I would check the capacitors first.

HI, this will occur when there is a power supply circuitfault that is located on the power supply board. this could be a failed capacitor or resistor of some sort.you will need to replace this damaged power board if possible to restore normal function.
It is unable to hold a proper AC current at this time.
hi there, check your power supply on cpu if theres a tripping off , so if theres then replace power supply. then switch it on again. then let me know what happen nexr..
reagards rated me... thanks
the lamp is simple; yet you can run into problems with this tv. be very careful replacing lamp. the plug in the tv can be damaged. (due to the design) lamp part #
DLP Projection tv, Models WD-57731, The tv powers on but the screen remains black, the audio comes on but after approximately 30-40 seconds,the audio starts to skip and then the entire tv system shuts down. I reset it a few times but that doesn't change the problem
