Need pin connections to lg vx-4500 for DC charger

4 important points or facts to note with chargers are as follows:
1. Supply voltage ~AC/Voltage (input, say 110Vac, 220Vac)
2. Output voltage (VDC)
3. Output ampere rating (amps)
4. Jack type for connecting charger to your phone.

What this implies is that you have to get your old phone to a store where phone chargers are sold or can be purchased (because of the connector jack)

However, you need to know the specific OUTPUT charging voltage (indicated as DC) and current for your phone

You could have a charging port issue, you may need to install a new one into the phone or order a backup battery plus a battery charger, interchange them as needed.

To locate the problem, it's important you own a multimeter, which can read DC Voltage and resistance.

If you do own one, then you can perform the following :

1. Battery
Set your multimeter in Voltage (DC)-mode.
Remove the battery from your phone and see what Voltage it's rated. (might be something like 3.7V, 4.2V or even higher.

The phone contains a minimum of 2 (small) pins, which is touching the battery, when it was inserted. The battery will have 2 or move gold-alike pads.Try to measure the battery at these pads to see the Voltage. If there are more pins, don't worry, just try to measure between all pins.
If the readout at your multimeter is roughly 0.5 Volts below the rated Voltage, the battery should be replaced.


Example :
Battery rated 3.7 V. Readout multimeter : 3.2 V
Battery should be replaced.

2. Adapter / charger
Insert the adapter in a wall-outlet (110 / 240 V AC)
The adapter, contains a plug, which inserts into your mobile phone. At this plug, you need the Voltage. The readout at your multimeter should be a higher than the Voltage-rating at he battery. If not, your adapter / charger is damaged.

3. Onboard connection
Set your multimeter in Resistance-mode, sometimes also shown as the Ohm-sign.
When charging your phone, your adapter is connected to your phone, redirected to the battery. Now it's time to check if there's a good connection between the phone-inlet and the battery-pins inside your phone. The inlet has in the center a metal pin. Try to connect your multimeter to this pin, and one of the battery-pins inside your phone. If there's no connection, to any of these pins, you'll get no readout. This might mean, the phone-inletconnector is not well connected to the board(*) of your phone.
(*) The green print, with all tiny electronic components.

The source of this damage might be :

A) While charging, the phone dropped on the floor.

B) Non-official adapter / charger
Maybe a higher rated current than allowed. A battery may be charged 1 / 10th of the specificated current. So, if the battery shows 1600 mAh, the batttery can be safely charged at a current of 160 mAh. If you use a 2A (= 2000 mA) charger, you can charge the battery, but results in a shorter lifetime of the battery.
Sometimes, even polarity might be an issue (reversed) or the non-official charger is supplying AC-Voltage instead of DC-Voltage.

C) Damaged onboard controller
Some phones contain a kind of controller-IC to control the charging proces. If the charger was supplying a too high Voltage or current (Ampere), it might end up in a fried controller-IC.
I such case you might have heard a "plop" when inserting this charger into your phone, or noticed smoke or a distinctive smell (of burned components)

Any repair for type A, B or C-damage, requires special skills and tools. If you lack any of these 2, go for a repair-shop or buy a new mobile phone.

Two possible causes:

1)your laptop charger is dead or malfunction

2)your laptop dc jack is loose or malfunction

If you need to turn around your charger at one position so that the laptop will charge, that means your dc jack is dead. Otherwise your laptop ac adapter should be replaced.

turn down the brightness to minimum required ,turn off anything unnesseary that you dont use as bluetooth ,Ir anyting like that, a trick use on my phone which seems to work atleast on my zte blade and my iphone 3GS is to connect the phone to the charger and let it charge to max then i restart the phone and connect the charger again for another hour and the batterylife seems to last one day more

Did spill the yogurt on the phone, or on the charger?

What happend when you plugged in the charger, specifically? Did your phone turn off, if not, were there any changes on the display, did the battery bars blink?

Also, if this is your AC charger for inside your home, do you have a car charger and have you tried it? If your car charger works, or if you are able to borrow someone's charger and IT works, then YOUR charger needs to be replaced. Best Buy, Wal Mart Electronic dept,or Staples, Office Depot, all these retail outlets sell replacement AC and DC ( 12v battery ) chargers. Cellphone chargers are notoriously easy to break, its not unusual to have to replace it during the life of any given phone.

You could try wiggling the connector, and watching the display to see if you have intermittent contact. Most of the ones I've had to replace were like that. They would only work if I pushed in the connector, or held it a certain way. If I just hooked it up and left it, it would not make a connection to the juice. Watch the display closely as your wiggling. You are looking to see if the display light up, or the battery bars to blink. If you can see it connect, even intermittently, you know your phone, and its ability to charge is okay,

Hello,

The reason your phone is not holding a charge is simply because there is a problem with the terminal head.

The terminal head is malfunctioning and is not charging the battery.

To fix the terminal head,

1. After removing your back cover and battery, remove the screws you see.
2. With the screws removed you can now remove the battery compartment.
3. With the battery slot removed you have access to the terminal head.
4. it is the metallic sheets that rests on the head of the battery when inserted into the phone.
5. Get a pin tip soldering iron and disconnect the terminal head from the green panel you will see,
6. replace it with a new terminal head.
7. Reverse the whole procedure for reassembly.

Another fault might be the charger or the charging port,

To test if it is the charger,

Try to use the same charger on another phone to see if it will work,

If it does not work then it is the charger.

To test if it is the charging port,

Test a well tested okay charger on the phone to see if it will work.

If it does not then the problem is the charging port and to change it
you follow the procedure of of changing the terminal but you have to disconnect the screen and the remove the charging port and replace it with another new one.

take care

I would suggest to check charger first by attaching it to another LG phone to make sure that charger is working or not.
Check your phone with another similar working charger to confirm phone.

you could fix it if you know how to soldered

did you try changing your connection settings.
