Sony Ericsson K800i not coming on!

White Screen of Death ( WSoD) generally comes in all phones, which indicates that the software in the phone has crashed. Reinstalling the OS in the phone fixes this problem. But you will loose some of your phone memory data.
The reinstalling of the OS can be done only by the authorised service centers and the cable and teh software for insatlling it will be provided by the phone manufacturer only to such centers.
try removing ur battery, keep it idle for sometime and then try switching on..

Won't Charge- Is there anything I can do?

well i dont have any long term ansa but here is a short term one while you find a new charger.

Take the charger and dismantle the end that plugs into fone. you should have 2 wires a black & white or black & red. Leave the blobs of solder on the end of the wires as this helps. Leave the wall socket end of charger in tact.

Take your battery out of fone. As with a normal battery you will see a (+) and (-) sign on it. Attach the black or darkest wire to the negative (-) metal square on the battery and the white or lightest wire (maybe red) to the positive (+) metal square on the battery (after trial & error i found a clothes peg to be the best form of attaching it). Leave attached for 15 minutes and this will give you around an hours usage when you put the battery back in the fone. If you leave it overnight then it will be on all day.

Basically you are making the circuit without the fone which bypasses your pin problem. Any charger will work with any fone as the charging components are in the wall end. Just make sure the voltage is compatible ie, 5v fone charger replacing 5v charger etc. Although majority of chargers are 5v.

I know this works cos i did it to mine last nite as i needed to ansa my emails. Really simple but a little drastic like i said but if the pin connector is broke anyway wot you got to lose?? I am a girl so if i can do it anyone can lol!!

Only drawback is you cant use the fone while it is charging unless you have 2 batteries and you use one while the other charges which is what i am doing. In fact i might not buy a new charger lol, i dont need one now ive found this method works.

Happy charging!! Hope this helps! Gail-michelle

K800i will not turn on infa red light is on when charging

I had the same issue.
It started where the phone went in a loop of restarting, getting a white screen, then restarting again etc...
I resolved this by downloading wontan server client ( ). You do need to purchase 1 credit in order to get an account. Follow the instructions (however, instead of holding down teh C button as instructed, try holding down keys 2&5 together) for this and it will resolve the phone not turning on/red LED issue.
I wouldnt recommend using the software for any other use as it can be, or it could damage the phone if not used correctly, but for this method, quite fool proof really.
I still had the phone restarting issue after this, however, i'm hoping to run the sony ericsson software to update the phone and hope that that works :)

Good luck. Hope this helps.
