How can i fix my nokia 6600?

Try a reset:
First turn it OFF, take the SIM card out.

Press * 3 send at the same time and turn phone on. Keep them pressed until the reset screen appears.
Give it time to reset.

The Best solution is go to a phone repairing shop and ask them what is wrong with your phone and then ask what to do!Dont go to a one shop pls goto more shops and ask !!!
Choose one shop and then repair from them!

If the screen is blank but you can hear the start up tone or you can still receive calls and messages then that means the LCD is the problem or the crystal which controls the display is damaged..have them replaced at any cellphone repair shops...if it just shows white and then turns off that means the software is corrupted,have it reprogrammed and if the program does not work the flash IC is the problem..have it repaired.

Sir iam the 5200mobileso this problem is mmc trackis changed the baalls so what is the solution please imediatlly

Another problem of the Symbian Operating Systems is the updates. The cellphones come ready to stop working when their calendar arrives to a bit more than the warranty time (3 in 3 years + -). As that, mobile phones stop working. The easiest way is to take the device to a store and they will make the update. That is free, once the device is totally yours and payed. But please, don't fall in the mistake of pay for it, some companies take the profit of taking money for a free operation. They earn twice because we make publicity to the marks using it too.
