Problem charging

[xboomer55]

One of my Tilts suddenly won't charge on some chargers:
HTC AC charger - OK
USB to PC - charge and sync OK
HTC compatible car charger - no charge
Blackberry AC charger - no charge

My second Tilt is OK on all four chargers (as expected).

I am suspecting a problem with the usb connector but looking for a reason why some chargers work and others don't.

Any insights would be appreciated.

Thanks

I saw a few weeks back a thread on this very forum that examines this problem in detail -- keep searching :)

I think I 've read everything relevant. I am looking for someone who has h/w insight into the Kaiser charging scenarios. I suspect mini-usb damage.

I am somewhat familiar with HTC's pin 4-5 implementation to detect a true charger as opposed to a usb connection that can also apply power.

I want to eliminate software possibilities.

How can a Kaiser charge from an HTC AC charger and also charge from a USB connection to a PC....but not recognize a car charger or a third party AC charger that does not implememt the pin 4-5 grounding technique to identify a charger (and not a generic USB connection).

That is where I am lost.

Looking for "inside-out" knowledge...not "outside-in", if you catch my drift.

If the car charger worked before, you can do an easy test. Just put in the car charger and do a soft reset. If it starts charging than, its only a software issue. I did a modification on a charger myself. Because I have different chargers using a normal USB cable, my device didn't charge alway as well. I modified a standard miniUSB cable by connecting the 5th pin to ground. When I use this cable for charging I never have a problem anymore. Succes.

I had exactly the same problem after I tried to re-set my device by poking the stylus in the mini-usb port instead of the re-set hole (tryng to do three things at once!). The port was mangled, and once i'd pushed it all back it wouldn't take a charge from the genric car charger. I bought an HTC branded car charger and it charges as good as a wall adapter.

I imagine that your suspicion of USB port damage is correct.
