3310 Signal Loss Problem

[GSM Super Star]

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
