Question about Coby TFDVD5000 Portable DVD Player
Hello, I have this DVD player connected directly to 12V car battery,and it works for a while. When i removed the battery and reinserted it again, there was no longer power on it. I also do some repairs being an electronics technician but my problem is that i don't have service manual or schematic diagram to look into in order for me to check the correct voltage output values of the power supply circuit. Would you please help me find one or teache me where and what specific parts that i need to check or replace? Perhaps other Coby DVD player model that has schematic diagram will do because the power supply design might be somewhat similar. Thank you very much for your help. Regards, Joseph

Check the voltage requirements printed on the capacitors in or near the power supply...If they are 16-18 volts, then it probably needs a 12 volt supply.

The easy way to discover the operating voltage of as device such as this is to A check the Spec label on the bottom of the machine. Check out the Dry Cell requirements. My guess this is a 6 /9 volt device.
