Insert a Card (SD Card or PC Card) and select CARD mode.
Replace IC9002 and/or IC9008 on the Main C.B.A.
NO
NO
Is there a 27MHz clock each at Pin 1 ~ 6 and 8 ~ 13 of IC9003 on
the Main C.B.A.?
Replace IC9003,IC9010, or
X9001 on the Main C.B.A. Replace IC9004 on the Main
C.B.A.
NO
Either IC9001 or IC9007 on the Main C.B.A. is defective.
Replace if necessary.
YES
NO YES
Check CARD DETECT (L)
signal line between Pin 36, 67
of P9201 and Pin 14, 15 of
IC9210 on the Main C.B.A.
Replace the defective parts if
necessary. Replace IC9204 on the Main
C.B.A.
Check IC9201
~
IC9203, IC9205
~
IC9212, P9201 (PC Card Slot),
and the surrounding parts on the Main C.B.A.
Replace the defective parts if necessary.
NO
Still NG
YES
Is there a 94.5MHz clock at TP9001 on the Main C.B.A.?
YES
Are there a V-sync signal at Pin 118 of IC9004 and an H-sync
signal at Pin 119 of IC6004 on the Main C.B.A.?
YES
NO
Check IC9011 and the surrounding parts on the Main C.B.A.
Repair if necessary. Is the voltage at Pin 4 of P9002 (SD Card Slot) approx. +3.3V?
May be caused by an improper contact of P9002 (SD Card
Slot and SD Card). Repair if necessary.
YES
May be caused by a communication error between IC6003 (Main microcontroller) and IC9004 (Card Processor) on the Main C.B.A.
Check IC6001, IC9210, and the surrounding parts on the Main C.B.A. Repair if necessary.
Is each voltage at Pin 2, 3 of IC9002 and Pin 2, 4 of IC9008 on
the Main C.B.A. correct?
Check the CARD YUV data bus between IC9004 and IC5302, and the surrounding parts on the Main C.B.A. Repair if necessary.
THE CARD PICTURE DOES NOT APPEAR CORRECTLY WHEN SD CARD OR PC CARD IS INSERTED.
NO PICTURE WITH NO OSD (BLACK SCREEN, GREEN SCREEN, ETC)
"NO CARD", "NO IMAGE" OR "CARD ERROR" APPEARS EVEN WHEN THE SD CARD IS INSERTED
NO
Is the voltage at Pin 4 of IC9204 or TP9202 on the Main C.B.A.
approx. +5V when the PC Card is inserted? Is the voltage at Pin 1 of IC9204 or TP9201 (PC CARD ON (H))
on the Main C.B.A. approx. +3.3V (High) ?
Check IC9201
~
IC9203, IC9205
~
IC9212, and the surrounding
parts on the Main C.B.A. Replace the defective parts if
necessary.
YES
May be caused by an improper contact of P9201 (PC Card
Slot). Repair if necessary.
Still NG
"NO CARD", "NO IMAGE" OR "CARD ERROR" APPEARS EVEN WHEN THE PC CARD IS INSERTED
NO PICTURE (BLUE BACK REMAINS ON THE SCREEN)
May be caused by bad contact of YUV data bus between IC9004 and IC5302 on the Main C.B.A. (there are some resistors.)
Repair if necessary.
ABNORMAL PICTURE (ONLY SPECIFIC COLOR DOES NOT APPEAR)
"NO CARD", "NO IMAGE" OR "CARD ERROR" APPEARS EVEN WHEN SD CARD OR PC CARD IS INSERTED.
IC9002 (Pin 2): Approx. +3.3V
IC9002 (Pin 3): Approx. +2.8V
IC9008 (Pin 2): Approx. +6.5V
IC9008 (Pin 4): Approx. +3.5V
