Changing battery in a Braun Oral-B electric toothbrush

The motor seemed to be fine but "lazy" due to a poor battery.

I've always had the idea to try to repair "things" before I throw it away. It is more or less a challege I've given myself. This was also the case this time :)

I used a big flatheaded screwdriver to turn the bottom of the thootbrush 45 degrees counterclockwise.

Push the motor/battery assembly out like its shown on the photo (red arrow).

Unsolder four points. 3 x for the motor (green circle) and 2 x for the battery (red circle).

Lift the pcb away and pull or lift the battery out of the plastic holder. Notice where the thin wires from the charing coil is running!

The order of the bottom assembly is coil spring, chipboard washer, coil, rubber washer, plastic cover


The battery I used is a Sanyo 14x50 mm. 1,2V NiMH, 1500 mAh rechachable.

Notice that the + on the battery should be towards the motor. Use a multimeter to find +/- on the battery.

Put the battery in place and solder the motor and the battery to the pcb. Make sure the thin wires from the coil is ok.

Samsung LE40S86 BDX/XEE LCD TV

Power ON the Samsung LE40S86 BDX/XEE LCD TV was not possible.

Remove the 16 Philips screws from the back panel.
Photo with the back panel removed.

A photo of the power board. Remove the 7 Philips screws to get to the soldering side of the PCB.

There was a problem with 3 of the capacitors on the power board. The capacitors location is marked with a red ring in the first photo. The old and not working capacitors had the values 1000 uF, 10V and 105C. I replaced them with 1000 uF, 25V and 105C

I put the TV together in reverse order and switched the power on. Hey presto, a working TV :)

VDO CDR 2005 CD stereo in a 2003 Opel Corsa

The Power ON/OFF and Volume button was not working.

It was very difficult to switch the unit on and off and the volume control was not working either.

I removed the 4 Allen screws (red circles) before I could insert the radio removal pins (below) into the holes covered by the Allen screws (placed according to the blue squares). Pulled out the Volume/On/Off button (green circle) as well.

Before you disconnect the connectors at the rear of the unit, make sure you have the security code.
You will find the code on your Opel Car Pass.

To get to the circuit board I removed 2 hex screws (red circles) on each side of the unit before separating the plastic front from the circuit board.

I used a soldering iron to heat the 2 soldering points at the rear of the circuit board (red circles).

Then I used a soldering iron to heat the 4 soldering points at the front of the circuit board (green circles). 

 Assemble the unit in reverse order.


Cancelling electronic lock after power supply is isolated.

After switching on the radio "SAFE" appears in the display.

Switch on the ignition.
Switch off the radio with the push control button.
Press AS control and hold down.
Switch on the radio and hold AS control down until a confirmation tone is heard.
"CODE" appears in the display after 3 seconds and the number of remaining attemps to enter the CODE appears, eg *10 ---- .
Enter the CODE digits (Opel Car Pass) using the preset controls 1,2,3 and 4

Example: The CODE is 1  2  3  4 .

Press preset control 1 twice and the display shows 1  -  -  -
Press preset control 2 three times and the display shows 1  2  -  -
Press preset control 3 four times  and the display shows 1  2  3  -
Press preset control 4 five times and the display shows 1  2  3  4

Confirm CODE: If the correct CODE can be read from the display, press the AS control until a confirmation tone is heard.

After 10 failed attempts, the radio unit will be inoperative. The waiting time between each attempt will be longer and longer. Ex. after 9 th attempt the waiting time will be 640 minutes.
