Troubleshooting-Guide V3
5.0 U700
Customer complaint
- TONxx
1. Check the phone with a test battery. When the phone turns on, check the
customers charger and battery.
2. Disassemble the phone and try to boot the PCB with EMU connector if the
phone starts up, check the customers housing.
3. If the phone starts in flash-mode (yellow status) when connecting with the
EMU connector, try to reflash with 1FF-flash file. If this is not successful
replace U700.
4. When the phone starts in blank- mode (yellow status)when connecting with the
EMU connector, try to make a reflash with an Image-flash file. If is this not
successful replace U700
5. If the phones current drain is ~55mA (red status) and decreases after a few
seconds to ~6mA when connecting with the EMU connector also replace
U700.
5.1 U50
Customer complaint
- CPRxx / TONxx
1. Connect the phone with the EMU connector while monitoring the current
drain. If U50 (PA) is defect, you could have a short to ground (board does not
start/disconnects immediately). Occasionally the PA draws slightly more than
the nominal current (check nominal current with a reference-board ~40mA). If
the PA gets hot, replace the PA (U50).
2. Check TX-output spectrum by setting the phone in TX-mode using the
spectrum-analyzer. Compare level and shape of the spectrum with a
reference-board if the level is to low or the spectrum looks bad replace U50.
3. Also check to the time mask with a GSM-Test-Set. If the signal does not
conform to specifications, replace U50.
