A repair if total dead is possible. Follow the money or the voltage in this case from cord to switch and from there to power supply--should be AC or wall voltage up to the power supply and then get rectified (changed) from AC to DC.
If no AC voltage past the switch--test it with a ohm meter--off no reading, on a reading etc.
The problem could be the power supply or the main board.all you have to do is to follow this simple and easy way of troubleshooting.
Remove the cover.
Plug-in your DVD player and power it ON to perform a voltage data/check.
Check the input power of the DVD.Use multimeter tester to test the AC voltage (AC range).It should have 120v or 240vac depends on the requirement of your DVD or the main supply that comes on the outlet.If no voltage reading,your power cord have a continuity problem.Replace it with the same type and A.W.G number standard.
If the power cord got voltage reading.Next is test the output voltage of power supply such as 5vdc for the main board and logic supply using multimeter (DC range).If no voltage reading,the problem could be the power supply board.
Check the following parts which commonly breaks on power supply board.
The power transistors (regulators)-It is commonly binds on heat sink and found on the primary of the chopper.use a multimeter (range diode test) to check if it is shorted.
The fuse-able resistors-it is the resistor that have low resistance such as 1ohm 2.2 ohms etc.It is usually found near the power regulators/transistors.Use multimeter (range resistance) to check if it is open or change value.
The capacitors-it is the one who can store voltage.If you have capacitance meter you can test that,if none just look at the appearance of the capacitor if it is bulge on top or leak.
NOTE: If you found the defective parts that mention above,replace it with the same type and ratings. When the problem is still there,The problem of the power supply is major and not for D.I.Y.I suggest to send it to the qualified technician or just buy a new one.
5. If the power supply have output voltage.The problem could be the main board and unfortunately the main board is not for D.I.Y because composition of the board is very sensitive.The only way to fix it is to buy a new main board unit.
I hope this solution could fix your problem.Please response if you have any comment and question.Thank you and good luck.
Remove the cover of your DVD player.Loosening all screw.
Check the input voltage of the power supply 220v/120v AC.If don't have input supply that comes from the ac cord,replace it.
If you have a input voltage supply comes from the power cord.Check the output voltage of the power supply such as 5vdc and 12vdc.
If the you don't have output voltage from the power supply.Check the fuse if busted,check open/change value of capacitor,check power transistor (regulator)if shorted and leak/bulging top capacitor of the power supply board.If you found any defective parts replace it.
If you have output voltage comes from the power supply.The problem could be the main board,replace it.
If you already done this procedure,test it by power ON the DVD player.
I hope this information will be helpful.Thank you and good luck.
Hey, not sure if you still need it, but there's a power cord for the PDM-2727 listed in an Ebay auction. Like you, I need the AV cord, er, at least I think that's the problem. The listing also shows an AV cord available for an extra $5 but it looks generic. Might be compatible though. I don't need the power cord or I'd ask the seller, but you might want to check it out if you still haven't found power cord/AV cable yet.
Although power cord is permanently attached, connections inside machine have broken off (from personal experience)from moving or jiggling. Unplug machine then check and see. That is, unless you are getting an "ON" red or green light when your machine ON. A question, did you have a power outage? In case you had one,and power is restore, the voltage surge can fry almost any electrical components including computer, refrigerator, freezer etc. Solution? ...a good surge protector.
This link is for an Audiovox DVD player, but it may fit yours or else you can cut off the plug on your existing power adapter and reconnect it to this one. Also try searching Google for "AC adapter 9V 3A".
