Problem
Service is aware of an issue where the CDMA V810, CDMA V510, and CDMA E310 may not be able to communicate to devices via an un-powered serial cable and in addition, some accessories may exhibit no audio conditions. This condition is the result of an incorrect IC Switch placed by the manufacturing facility. Units with this incorrect part will have B+ voltage applied to pin 7 of the CE Bus Connector at all times. Note that the use of a powered serial cable, Junior Board, or USB cable will mask the issue.
Solution
Factory and part supplier have implemented improved parts verification process.
Service Action
Customer Returns:
When servicing affected CDMA V810, E310, or V510 customer returns, with customer complaints of “No Serial Data Communication” or “No Accessory Audio” verify the phone has the proper switch IC in the following manner:
1.With the phone powered off and a charged battery installed:
a.Measure the DC voltage on Pin 7 of the CE Connector.
b.A correct part will indicate 0 DC Volts on Pin 7 of the CE Connector.
c.An incorrect part will indicate the battery voltage on Pin 7 of the CE
Connector.
d.If battery voltage is present on Pin 7 of the CE Connector, Replace IC303 with the correct part number 51-46101-01.
e.Figures 1 and 2 indicate the IC303 placement on the respective models.
f.Figure 3 shows the correct part marking HXxxx.
