Power switch not turning on - Nokia 5140i Cellular Phone

possible problem in light control module or faulty relays

This is fairly easy to diagnose. Down by the brake pedal there is a switch. You may have to remove some trim panels to access it. There should be one wire with power all the time. There should be another wire that has power only when the brake pedal is depressed. If there is no power on any of the other wires with the brake pedal depressed than the switch is bad.

If there is power than the more common problem is the turn signal switch. I know it doesn't sound like it could be the problem but let me explain how it works. the turn signal and the brake use the same bulb. In order for the correct power source, brake lights or turn signals, to get to the correct bulb the turn signal switch is used. If you are not turning the power from the brake switch is routed through the turn signal switch and then sent to the two brake brake bulbs. If you are turning to the right power from the brake switch is cancelled to the right bulb and replaced by power from the turn signal flasher.

One quick way is to see if the third brake light is working. If it is you know the brake switch is working since power to the third brake light bypasses the turn signal switch.

Good Luck and let me know how it goes!

The brake light wire leaves the brake switch and goes into the turn signal switch. They often share the same wire: the rear turn signals and the brake lights. When turning, that side is routed through the turn flasher, but you get a steady brake light on the other side.
So you have power to the brake switch. Pull apart the connector for the turn signal switch, and see if you have power in on the brake wire (with brake depressed of course) going into the turn switch. If you have power in, plug the connector together, and see if you can backprobe the connector with test light or voltmeter, looking for power out to the rear brake lights. If power in, but no power out, the turn switch is probably bad.

Sometimes they just need to be reset
1 turn off power to switch (Circuit Breaker off)
2 wait 30 seconds
3 re - turn on power to switch again (Circuit Breaker on)
4 wait for lights to turn on by themselves ( about 15 seconds after power is turned back on)
should be OK after this remember to not enter the beam after power is turned on ...... (see #4 above) as this would make switch beam super sensitive. Hope this helps

The hazard switch gets power from the horn fuse which is hot all the time, and from the turn signal fuse which is hot when the key switch is on. The turn signal switch gets power from the hazard switch and both use the same flasher.
So if the turn signals work but the hazard switch does not power the lights, and both fuses have power, I would say the problem is inside the hazard switch.

Try this reset, it may work:

-Turn Off power switch
-Select 90 degree washing
-Press and hold Start
-Turn ON power switch and keep pressed Start button 10 sec
-Depress Start button
-Turn Off power switch and turn On again and thats it...

Simple power hack, to do this, kind of like hot wiring your computer.

Turn the power on at the wall, Flick the switch on the back of the computer (if there is one on the back) to the on position, make sure the cable is plugged in, and turn the power off at the wall, hold the power switch on the front and turn the power on at the wall.

This will cause the power to jump across the switch, causing the computer so sound a bit like a motorbike being started.

The power will come on it will turn over click and go off. After this turn the switch of at the back of the computer, and turn it back on, and the computer will boot up.

The first bit of this is just charging the capacitors in the power supply, the second bit is turning your computer on.

Do you have power at both sides of the brake switch when the brake is applied? If so it sounds like the turn signal switch is bad. try turning on and off the 4 ways a few times. sometimes this will clean the connections and it will start working.
The power goes through the fuse to the brake switch. from the brake switch to the turn signal switch from the turn signal switch to the tail lights. If the 4 ways are on the power goes through the 4 way fuse to the 4 way flashers then to both sides.
If the turn signal is on and the brake is on, the turn switch cansles the power from the brake and uses power from a 3 fuse and flasher for the side that the turn signal is called for.
If I typed to fast let me know. I can answer any questions you might have.
If this helped you please vote 4 thumbs up. :-)
good Luck and God Bless

There is a power switch on the bottom of the display and a power button on top. The power
switch is used to cut off power completely, whereas the power button turns the screen off but
allows the remote to continue working.
To turn the display on:
1. If the power light on the front of the display is off, turn on the power switch on the bottom
of the display.
2. Press the POWER button.
To turn the display off:

Nikon Coolpix s3 powers on OK when switch is on auto mode, but when switched to "Scene" mode cannot shoot, switch back to auto mode / movie mode, or turn off. If power is turn on when switch is in "Movie" mode, everything is OK. Help!
