http://www.experts-exchange.com/Digital_Living/Hardware/Home_Theater/Wiring_Accessories/Q_23306781.html#discussion The following question is a continuation of this thread. I thought the problem was solved and I am feeling" o so close" but still no cookie. At the end of the above thread, I thought all I had to do was to get a different polarity dc cord tip. As the point winner cogently noted, all I would have to do then would be to switch the tails attachment points and all would be well. Well it is not. I tested the continuity of the dc jack to see if there was a short by wrapping one pig tail around my positive probe and then touching the barrel and probing the inside of the tip. I only had one side leave 0. Ok so I switched to the the other tail attached to the negative probe and did both barrel and tip. Again only one touchpoint left zero. If i understand this aright that means there is no short in the jack and wire. My projector seems to be putting out the proper MA. It is supposed to put out 200ma If 200 MA is the same as .002 Ma then it is. i got this reading by going deep with a thin copper wire on my negative probe and just touching the positive to the tip. Unfortunately, changing the pig tails black and white(which I discovered by calling the vender is the center feed.) to positive or negative results in no motion up or down by the screen when the projector is powered on or off. Neither will show any current when tested at the pig tail attachment point. So now i am befuddled again. The correct amps seem to be leaving the power supply. The dc jack and cord does seem to have proper continuity and, therefore, no short. No amps are detectable at the pigtail splice. wah!
