Figure 8:PLL-SDAT Signal

Figure 9:PLL-SENA Signal

No RX (no Rx calibration…RSSI reading fixed value)

COBBA / MAD faulty /broken solder balls

Check if the 13MHz IF on pin 23,24 N700 SUMMA change the amplitude if you change the generator frequency
level

Check if the RXC impulse on pin 36 N700 (SUMMA) change the amplitude if the generator frequency level is
modified (see the diagram below)

(change the operation mode first to "RX BURST MODE")

Check R725 if any or low signals are measurable

Change COBBA N200(rewrite SIMLOCk and update the handset)

If the fault persist MAD or the PCB should be the reason

In this case swap the handset because MAD is not changeable

Note! Rewrite SIMLOCK and IMEI entries with use of the Nokia security SW (SSSW) and make a SW-update or send
this phones to the SACE, if this procedure is not permitted to you
