2. Description 
During the production of main unit for February 2012 production, a connection failure   
 
 
occurred between the 7 inch LCD connector and BL Interface Harness connector which is   
 
 
connected to LVDS PWB.   
                 This led to a problem with the backlighting causing flickering or failure to illuminate. 
 
 
As a tentative measure, the 7 inch LCD connector and the BL Interface Harness   
                 connector (connected to the LVDS PWB) have been connected directly and soldered as a   
                 countermeasure. 
 
 
 
Note: When replacing the 7 inch LCD with tentative measure in field, please make sure to   
 
 
procure both 7 inch LCD (VVLLW70AT98-1) and BL Interface Harness   
 
 
(DHAI-4635FCPZ) as service parts for replacement. 
 
 
 
- After implementation of tentative measure 
- Normal condition 
 
 
 
 
 
 
 
 
7 inch LCD connector and BL Interface 
Harness connector are connected. 
7 inch LCD harness and BL Interface 
Harness are soldered directly and 
covered with shrinkable tube.
