3510i No Lights or Tones

I have a 3510i which has the following problem:

1.Start-up tones and normal tones not working
2.Display and Keypad lights not working

Everything else on the phone works fine except these, anyone have an idea where the problem could be? I have reflashed the phone along with an intensive liquid damage cleaning process, but still none of the above work.

Any help would be appreciated.

Thanks

Hi!

About tones: If You use PIN code try to enter wrong one first and press OK, on my phone tones start work, than enter right code.
But I don't know anything about lights, sorry. Maybe You should visit service master.

GoodLuck!

;)

Thank you for your help, but sadly that did not work! I think this could be a similar problem to the old 3310 ringer problem, and wondered if there could be a repair possible for the 3510i?

Thank you anyway.

Hi Mamber pls go to settings>phone settings>start-up-tone>on
it should work, if ur diaplay and keypad lights not workin change the LED of ur Phone.

cheers

Thanks for your help, but much more serious than that! UEM faulty!
