3310 Signal Loss Problem

I have had this phone for a while and all of a sudden the signal has just gone. I know it isnt the sim card as it works in another phone.

I have had the phone apart and cleaned all the connectors with no luck. I understand this is common with some nokias so does anyone have instructions and a diagram so I can have a go at fixing it?

Many Thanks

Have You droped it?
I can send You a service manual...but run a test with Eeprom tools
And post results..I hope we can find a solutions...
Regards!
