check contrast, eeprom data, resolder cpu,

Load different eeprom from other good C45, then repair with LOG/MAP file (repair check sums)! I think that contrast must be good in this moment, but still no display!!
Only rehot CPU is solution?

I have repaired few c45 and mt50 with this bug.
try to get working one and check upper part of pcb on not working one, probably you will find broken lines near lcd connector (even if they look for 'good' they are cracked under lacquer).
Good luck!

ps. If you didn't succed then you can send phone to me- I will repair it for free for you

regards!
