Disassembling & Re-assembling of FPC (Flexible Printed
Circuit) and Y-Buffer(Upper and Lower).
Removal procedures.
Full out the FPC from Connector by holding the lead of the
FPC with hands.
CLICK ON THE PICTURES TO ZOOM
Assembling Procedures.
Push the lead of FPC with same strength until to be
connected completely.
Note: Be careful do
not get a damage on the connector pin during connecting by mistake.
Assembling & Disassembling of Flat Cable Connector of
X-Main Board.
Disassembling Procedure.
Pull out the clamp of connector.
Pull Flat cable out press down lightly.
Turn the Flat cable reversal.
Assembling Procedure.
Put the Flat cable into the connector press down lightly
until locking sound (“Dack”) comes out.
Assembling & Disassembling the FFC and TCP from
Connector.
Disassembling of TCP
Open the clamp carefully.
Pull the TCP out from Connector.
Assembling of TCP
Put the TCP into the Connector carefully.
Close the clamp completely. ( The sound (“ Dack”) comes
out.)
Notes : TCP and Connector was connected surely.
Checking whether the foreign material is on the Connector
inside before assembling of TCP.
Be careful do not get a damage on the board by ESD
during handling of TCP.
Misassembling of TCP
The misassembled of
TCP is the cause of defect.
Checking method of misassembled of TCP.
- Disconnecting H3 from CN8006 of LBE.
- Whether H8 and H9 are connected.
- Checking the resistance between Pin 1 and 5.
- Resistance > a few [ KOhm] :OK
- Resistance < 20 Ohm : At least, more than 1pc of TCP is wrong.
The procedure of assembling and disassembling of FFC is the
same as TCP.
