Betokoch 0 Posted January 27, 2010 Hello everybody, I have a DVR model CPD505 and when I connect it to the energy, it produces a continuous sound like "beep" and does not work. Neither the fan works. Do you have any suggestions to make the DVR function again? Thank you very much for your attention. Share this post Link to post Share on other sites

scorpion 0 Posted January 28, 2010 Are you a tech? Can you check the voltages with an Osc? You may have the voltages, but the external power supply may be leaking AC. Can you get another external power supply to test? Share this post Link to post Share on other sites
Betokoch 0 Posted January 29, 2010 I checked without a hard disk and it still doesn`t work. I will check the voltages, but I only know the hard disk voltages, do you know the other output voltages? Thank you!!! Share this post Link to post Share on other sites
