My Sony Ericsson Cyber-Shot C903 will not switch on. I have tried to charge and and the camera button on the side lights up blue but then goes out and nothing comes up on the screen.

Hi, Free unlocking is not possible for your phone model. but you can get the accurate unlock code for a Sony Ericsson C903 from www.classicunlocking.com/sony-ericsson-c903/rs16wp9/ at low cost.

======================================
UNLOCKING STEPS FOR SONY ERICSSON C903
======================================
1 - Switch ON your Sony Ericsson C903 without any SIM Card,
2 - Press the left arrow key/button once,
3 - Press the button * twice,
4 - Press the left arrow key/button once,
5 - The message "Personalize with MNC2" will appear, (or you will have displayed an unlock menu, select the lock you want to unlock)
6 - Enter the Unlock Code.

If your Sony Ericsson C903 does not have a left arrow button/key(e.g. Sony Ericsson W950i) and on a few phones(not all) that have a "JOGDIAL" you must press the "down arrow" key/button instead of the "left arrow" key/button for step 2 & 4. We mean by "Down Arrow" to direct the Jogdial down! In the Sony Ericsson W950i and some other models, the down arrow button/key would be located on the side of the phone.

Hi! I went through this tonight with my Cyber Shot too. There's a software update you need to install from the Sony Ericsson site. I've got the link to it and the information about it here on my blog - http://jackcullen.blogspot.com/2009/12/sony-ericsson-c093-dilemma-network-3.html

Thanks,

Very funny solution, but helpful.

Got the same problem. Display and keyboard lights goes black after lens cover open. I can take pictures and videos.

For a short period of time phone seems to be died after switching camera off. Then lights goes back.

It is a phone feature, try checking if the phone is well closed or if you have the camera app running on the background

Cheers
