S35 with dead display
 

Hi, after unlocking and killing my S35 I've reflashed it with fw24 and rewritten IMEI; phone turns on, display light is on, beeps for network (I've no PIN) but the display is blank...
I tried to set contrast with X35 service Tool 1.7 by Martek but still have the same problem.
Phone works ok: can call, receive, use AT commands, but the display is blank....
I think isn't hardware broblem: I've only killed-reflased it.

Any suggestion?

Tnx
