Question about Cyberhome CH-DVD 300 DVD Player
Check voltage on the two extreme wires of the CN2 connector on the power supply board. On the yellow wire has to be 12V against one of the black wires (GND - ground, negative) and on the red wire you must measure 5V. If voltages are bellow this levels there is a problem with the power supply. In most of cases the 2200uF/10V capacitor is blown. I recommend to replace all the electrolytic capacitor of the power supply board with new ones. Observe capacitances and voltages of the new capacitors! You can use higher voltages (but never lower!) but the same capacitances. You can make it with little soldering skills.
Have a good luck and sorry for my English...

If there are no indicators that it is receiving power such as timer/clock, standby light, whirring sound when first plugged in, then initially, it would be safe to say that the internal power supply is the culprit. For the moment, course of action would be:
