FIELD SERVICE BULLETIN

FSB Number: LVCCFSB2005-230 (Rev B) Author: Darwin Garcia Date: August 18, 2005 Total No. of Pages: 3 Subject: GSM Razr V3 SIM pin broken Model Affected: V3 Level of Repair: 3 & 4

Problem

Service is aware that some V3 Razr units have been returned with complaints related to SIM detection. In several cases, service personnel have reported broken/bent pins in the SIM connector. The failure mode analysis indicates that the angle of insertion during SIM placement plays a fundamental role in the SIM connector damage.

Fig 1. A SIM Block pin in the front row is broken.

Solution

Short Term: A protective tab has been added to the back housing to prevent the user

from bending or destroying the SIM connector front pins. The tab forces the SIM to run in parallel with the SIM connector’s surface. The new rear housing was initially implemented at the factory in units built on black Razrs.

Service Action

Customer Returns:

When servicing V3 Razr unit with an “Insert SIM” complaint:

1.) Troubleshoot the unit following service standard procedures.
