I have the player plugged in and everything but it wont power on, it stays in stand by mode, none of the buttons will turn it on. any solutions?

1. Power button: Locate the power button on the front or side of the DVD player. Press and hold the button for a few seconds until the device turns on.
2. Power outlet: Unplug the DVD player from the power outlet and then plug it back in. This should turn the device on.
3. Power strip: If the DVD player is plugged into a power strip, turn off the power strip and then turn it back on. This should turn the device on.
4. Manual: Consult the manual of your DVD player if you have one, it may have a way to get the device out of standby mode.
5. Using the buttons of the DVD player: Some DVD players have a button on the front or back of the device that can be used to turn it on and off. If the device has a button, try pressing it to turn it on.

It's worth noting that these methods may vary depending on the specific model of your Sony DVP-C670D DVD player. If none of these methods work, you may need to purchase a replacement remote control or consult a professional for assistance.

Try holding the 'tone control' and 'info' buttons and pressing power. This should allow the unit to turn on. See what the front display says at that point. I tshould show some kind of protect code. If the unit turns on and stays on normally after that, then you may have had a temporary problem that was cleared by disconnecting everything. If it turns back off right away, then you will have to get it repaired as something internal has been damaged.

The solution to no post on a computer is to remove everything that you can, take out the hdd, the ram, and optical disk and see if it boots. If it does, put the RAM back, then try again, if it does, put the hdd back and try again. It is a process of elimination. If everything is removed and it wont boot, it may be the motherboard. I have also seen bad batteries do this. There is a chip inside the battery that wont let the machine boot when the life of the battery is expired.

some tv's always have standby light on, even iff you turn off by tv button. solution 1: with light on, press a number on remote. solution 2: with light on press stand-by button on remote. solution 3: with light on push the 'on' button on the tv set. solution 4: unplug tv set, wait a few seconds then plug back in, if no light then turn on tv using button on the set, and then channel number.

Turn off. Put in Hold mode. Hold down middle button. Plug in while still holding middle button. Now reformat the Clip and update the drivers.

Make sure it is not in download mode!! a little switch on the back of the device
