3310 automatic off - GSM-Forum

zoboz · 07-01-2003, 16:48

1st,
I have 3310 with "automatic off" problem. power on ok but while welcome logo is being displayed, handset is off.

Battery is fully charged as charging is ok.

2nd,
no signal prob. heated up the hagar, pa, ant swt. still no signal.

3rd,
charging prob. first time charge is ok but once charger is pluged out. "Charging" is displayed and batt signal is like when phone is charging. so it's like the phone is charging but it actually not.

any idea? Thx

1. Change batt contacts or clean them, Change PA
2. Change Cobba and do update faid
Did u just heated mentioned components or u change some of them >>>?
3. Look for capacitors after control fuse maby faulty, see ccont also chaps if nedeed

finally i have time to be online......
DrMobile, thanks for the pic. It is now charging ok.

for NO SIGNAL prob,
how do you actually identify which chip is not working? it could be the hagar, antena switch, ccont, cobba and so on. is there a simple ways to identify all these?

b0ba · 07-05-2003, 20:55

There are some ways:
1: Enable Net maonitor.
If RSSI (Recieving Signal Strength Indicator) is greater then -60dB then Rx part is ok.
2: Change PA...
3 If netmonitor shows that PA is always on then reball/change cobba/hagar.
I think your pb will be solved
