My device is not charging more! I throw it?

Hello,
Acquarius83, on your pictures Nbr. 3 and 4, you can see a chip (U13), this is a LTC3455, and it is the Power generator for your TomTom.
Pin 9 of this chip is the battery charging power supply and it is going directly to the + pin of the battery connector (where the battery red wire is connected).

Looking at your photo 4 as it is shown, the battery connector is the white 3 pins connector on the middle left of the board. The + pin is the leftmost pin.
First, unplug the battery and plug your TomTom board USB connector to an USB 5v Power supply or a PC USB port; the TomTom green Led should be lit.
(If the Led doesn't lit, the USB connector may not be well soldered, but it seems to look good at your second pictures set, or the 5,6v protection zener diode may be shorten and there is nothing more you can do, except replacing it.)
Check the voltage on this + pin of the battery connector; you should read 4,2v. (take the ground at the metallic rectangular frame, GPS antenna frame or screw, etc...)
Now plug the battery in and check the voltage again ; the voltage should be around 3,9v, depending on the battery initial charge.
If, when the battery is not plugged in, you can not see any voltage on the + pin of the battery connector, the chip is probably dead.
In this case, there will be probably no voltage either on the three round ferrite coils.
Even if the device is not switched ON, there should be a voltage on two coils when there is +5v power on the USB connector.
Looking at photo 4 :

- the coil on the left of the chip should read 3,33v
- the rightmost coil should read 4,97v
- the middle coil, just at the right of the chip, reads 0v, but will read 1,46v when the board is switched ON (press a few seconds on the Power switch).
If the ship is dead, it can be replaced, but this is a hard work (especially on this board because components are very close to each other) and you need a hot air station.
I used to replace this chip a few times to repair some x20/30 TomTom, but in your case, if the chip is dead, I think you better have to buy an other GPS.

What can I do?! burned components do not see ... post some pictures? I posted some pictures, I hope you understand why not charging ..... Rating: 5
