I cracked my LCD screen and took it in for repair, once my phone was returned back it wouldn't charge anymore and it says 'charger not supported'. I took it back to the repaier who said that this problem was due to my PCB being faulty. He say's that they did not break it as the LCD is a seperate part and the wouldn't have touched my PCB- does this sound right?? I think it would be a huge coincidence if my PCB broke just at the same time I let someone dig around in my phone..
My wife had the same problem with a car charger and also a 5V USB socket on a laptop travel charger. We have just sent the car charger back for repair/replacement. However as a curious electronic engineer I did an internet search for the specification for charging via USB and discovered that there is a new specification which is only a couple of years old, and is presumably what Nokia are using on the 6500. This states that to be recognised as a charger rather than a USB port, the USB D+ and D- lines must be shorted together. So I opened up my laptop in-car travel charger and soldered a bridge between the middle two pins on the 5V USB type A socket (previously floating) - MAGIC! - the phone now recognises the charger and happily charges.
I had not been able to find the above info anywhere before except in the technical spec for the new charging over USB spec - I found it here:
So I hope this info helps demystify this and stop some of the frustration users are experiencing here. Perhaps a real Nokia engineer might like to comment.
Apparently from what I've read there is a component that must be replaced within the phone.It's the R53575 BTemp 47k. I think its on the PCB. I'm really suprised that Tony's method worked here as I think it's this faulty component within the phone. When two devices don't charge your phone it usually implies the phone is at fault. My phone doesn't charge via usb or wall charger.
If you want to communicate with the computer don't you have to have the D+ D- lines ready to take connections?
Just charging my phone would be good for me though. So if we're dealing with a wall charger. All I have to do is open up the charger find these pins and solder the D+ and D-ones together. I'll give this a go but I still think it's to do with the phone itself.
Today this started happening with my phone, so we tried the flicking/slapping the charger approach first and would you know - it actually worked
It seems quite easy really. Just use a needle or something similar to clean out the socket into which you put the charger. Mine was full of fluff which meant that the charger jack would not go in fully. Clean it out and off you go
Hi lalunatech- thanks for the post! I actually still use my Nokia 6500 (I still love it) but plan on getting a smart phone by the end of the year. Good tip to know re the plug. I actually ended up arguing with the repair man and making them fix it free of charge- but who knows- maybe they just opened it up again and realised the plug was not in properly! Thanks for the post, i'm sure others will find it useful.
recently had the same issue, but i found the couse in my case... i messed up with the wrong phone switching by mistake the battery from an nokia c1 to a nokia 2700 classic. when i put back the old battery my phone is back alive again.
