2. Description 
During the production of main unit for February 2012 production, connection failure  
 
 
occurred between 7 inch LCD connector and BL Interface Harness connector which is  
 
 
connected to LVDS PWB. This led the problem with backlight, such as flickering or failure  
 
 
to light. 
 
 
As a tentative measure, 7 inch LCD connector and BL Interface Harness connector which  
 
 
is connected to LVDS PWB has been cut and then 7 inch LCD harness and BL Interface  
 
 
Harness are connected directly and soldered. 
 
 
 
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.
