Hey ive had my sayno 7400 for over 2 years now and today I pulled it apart to change the keypad part. I was real careful pulling it apart n got it all back together sweet.. turned it on and it got reception for about 10 seconds then stopd and since it doesn't pick up any. I've called telecom and they said to try a couple of things which hasn't worked.
 
I can't really afford to get the phone sent away to get fixed. wondering if anyone has had any problems like this or anything i could try? any help would be great. thanks
