TransFlash Memory Card – no function
Insert a known good TransFlash card.
Under Menu – Settings – Phone Status – Storage Devices the Memory Card should
appear next to the internal phone memory.
If not, disassemble the phone and do a visual inspection of the TransFlash Connector
itself. If there are any visible damages/bent contacts/solder shorts or dry joints, change it.
Check SD1_DET_B
- Without TransFlash card inserted there should be a HIGH signal of 1.9Vdc, if not
check R5811
- With TransFlash card inserted the signal should change to LOW signal (0V)
If SD1_DET_B without TransFlash card inserted is ok (HIGH/1.9Vdc), but is not switching
down to 0V with inserted TransFlash card, replace TransFlash connector J5801.
Check VMMC_2_9V
ok, it is probably a problem with the ARGON
service center.
