Ok, I installed a 27mhz XO2 Tent clock into my Samsung HD841. It worked for about an hour than the transport freaked out and the screen went green. Cycling power does nothing. Im still getting 1.75volts at the clock output, with 3.5v input. I however cant seem to see a waveform on the scope. Its just a straight line. When I first installed the clock I saw the waveform when I was checking things out. The player is acting like it doesnt have a clock, when you power it up the screen just says load. The transport doesnt spin, the drawer wont even open. Can anyone help me out here. Is it possible the crystal died? Even though I still measure voltage?
