Default Tent Clock Problem.....

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?

3.5v input into the crystal. 1.75 out from the crystal, but Im not seeing any waveform on the scope. When I first installed the clock I had the waveform, but now that the player is in a funky state Im not seeing any waveform. I am correct thinkin that no cd spin, no tray open, no response to controls except power is clock related right?

Yes.
Put the original oscillator back and test it.

You need 5 Volts as power supply on the XO, not 3.5V.

That DVD player must work with a 3.3v clock.

Correct, the player works on 3.3v clock.

I also tried the above circuit but the output voltage (pin 5 of XO) is 5V .... just curious , may i know how did you get 3.3V ?

Guido had corrected the 22K and 56K resistors to be 2.2K and 5.6K respectively somewhere on this thread. Maybe you may want to try it and see if it works.

While troubleshooting, try not to turn on the CDP too long without the clock no signal , or else your lens may jerk/focus/vibrate then get damaged.


good luck !!

I purchased the XO2 from guido, so getting 3.3v was a matter of changing a resistor value. Ok is there anyway to plug in the old crystal which is a 2 leg instead of guidos, I think the crystal is bad. It is looking very wierd on the scope.

The 2 leg crystal will not work on Guidos PSU module. The suggestion of CarlosFm is a better way to check if Guidos XO is bad and to confirm if your player is still working ..
