Do you have a connection guide for each screw (N, COMMON, A1...) ?

color code guide

from the looks of that wiring someone was not following the color code, So following the code may not help unless there are marks on the board.

1. Before starting, turn off the power with the power switch next to the power cord then disconnect the power cord.
2. Remove any data cables since you will be spinning it all around.
3. On my printer (other models may vary) there are 5 screws that need to be removed first:
Facing the front, open the large lower front cover and remove the three screws on the front right
Turn to the back and open the back cover. Remove the two screws on the left. Notice any screws that are different and remember their position.
4. Slide the right side cover towards the back. It should come away easily. Set it aside.

You can unlock your phone in these two different ways:
* You can buy an unlock code from web. (It is a simple and very easy solution without any harassment, I have added some trusted links where you can buy them) (Link Attached)
* You can Flash your phone to unlock it. (It is an advanced way, you have to have advanced knowledge in Mobile Phone Service or Repair) (Link Attached)

Thank you..

Here's what worked for me.
Carefully remove the back cover using a flat bladed screw driver. The battery can be spotted easily as it is centered and takes about two-thirds of the area. Do not remove the battery. Rather, you will see a point where the battery wires are connected to the circuit board around the bottom right of the A1 (assuming you put the A1 in an upside position, the camera lens being at the top). Try to loosen the plug by pulling the connector backwards using a small flat-bladed screw driver or even with your nails. Do not try to pull it back all the way, just enough to stop current flow. Make sure the battery is now disconnected by trying to turn the A1 on. Then, connect the A1 to a charger (I used a USB cable to draw power from my laptop). Now, reconnect the battery by plugging the connector back in. Now press and hold the power button until the screen turns on. The battery should be charging now.

you will need a Canon Motor Drive MA for that.
On the batterypack is a Remote Controle jack.

Can i connect a powered subwoofer to center channel pre-out connection inYamaha DSP-A1

If you soldered something and now it wont work ,check the items and connections that you soldered.

Your EQ will be connected to the amp via one of the Tape loops. Connect rec out from the EQ to play in on the A1 Tape input,and rec out from the A1 to play in on the EQ. Then select Tape Monitor on the A1 to hear sound with the EQ settings applied. It won't affect the surround channels,only the main ones. You can also connect the EQ across the pre out and main in sockets for the front channel on the A1

The manual for this remote control is embedded in the operating manual of the DVD Player DRC 220.
