20 Most Recent Sony Ericsson Xperia U Black Rubber Gel Case Cover Questions & Answers

I experienced the very same problem twice.
The red led would either stayed on all the time when charger was connected or it blink whenever I'd push the power button on the phone, but the phone would not turn on.
My solution was to unplug the charger, take out the battery and the sim, keep them separated for at least 48-72 hours, then put back the battery, connect the charger again (don't use your computer's usb port, use a real wall charger, preferably the original one), turn on the phone.
If it doesn't turn on immediately, let it charge for a few hours and then try to turn it on.
I revived this phone twice using this method, first time I thought I was just lucky, but apparently it's reproducible.

Hope it works for you too.

Does it work with just the battery or just the power supply? May need a new battery as they do not last forever. It may also need a new powers supply. Test if it works for one but not the other as that is the key.

Probably shorted the power supply, but may have only blown the fuse. If you have a manual find where that fuse is and replace it. If it is not the fuse, replace the power supply, and cord as it is not expensive and is worth a try. Unfortunately, you may have fried the mother board. Amazon sells one for less than 50 dollars and it is easy to replace if you follow the instructions. There is a chance you may fried the CPU which could be more expensive. The hard drive is not, but may have been damaged too. It's worth a try on all counts as Sony's are not cheap to reacquire and that accident is not covered by your warranty as something that happens under normal use.

Check whether your sim is placed properly in the slot. Try to reinsert the Sim. Still if you face the same problem then your phone might be locked to particular Network. To solve this problem you need to get your phone unlocked. You can unlock your Sony Ericsson phone using unlock code. You can get the unlock code for your phone from your Network service provider or Network service provider or any third party online vendors like Unlock-Zone.com here you need to specify your country, current Network name, IMEI number of your phone. Then they deliver unlock code to you through mail with unlocking instructions. Using this you can unlock your phone from Network lock easily.
