If your Philips DVP642 DVD Player does not turn on, but your standby light is flashing, a failed capacitor might be your problem. The C316 capacitor is a very common fault on this model Philips, but it may not be the fault with yours. This guide should help you determine if this fix is for you.

Replacing the capacitor is easy and cheap. Your local Radioshack should have them in the store or you can purchase them online for about $.20 (digikey.com, mouser.com, jameco.com)

The power supply board is the tan colored circuit board.
-
There are 3 ribbon cables that need to be disconnected. One can only be disconnected at the Main Board. (green)
-
Unscrew the 3 mounting screws and release the 4th corner of the board from the plastic standoff using a pair of needle nose pliers.

Capacitors can store large amounts of electricity. It is advised that you take the time to discharge them using the proper tool and not just a screwdriver. Touch both leads with a resistor to do this safely.
-
Use a multimeter to ensure that each capacitor is fully discharged.

Be conscious of the orientation of the new capacitor. Electrolytic capacitors like this one are polarized and will only work in one direction.
-
Notice that I am using a capacitor with the same capacitance, but a higher voltage rating. This only increases the voltage the capacitor can handle before failing, it does not raise the voltage of the circuit. It is important not to use a lower value, however. Be sure to use the correct capacitance (1000uF).
-
The grey line indicates which side is negative. The negative side also typically has a shorter lead. On the board, the "shaded" half of the circle with the hashmarks is the negative side.
-
Insert the new capacitor and bend the legs outward to help hold it in place when you turn the board over.
-
Solder the leads and clip the excess length.
