Is the RX0.1.2.C signal input from the INPUT5=DVI Connector (SC1900) to Pins (2)(3)(51)(52) of IC1900 (HDCP)? Are the DVI-H/V and the DVI-R/G/B signal output to Pins (18)(19) and Pins (23)(26)(31) of IC1900 respectively? Are the DVI-SR/SG/SB and the DVI- H/V signal output from the MD Connector (P1900)?
Are outputs at pins (12) and (14) of IC1917 both (L, H)?
Check AV settings. Check IC1911 and its peripheral circuits. Check IC1917 and its peripheral circuits.
Check IC1900 and its peripheral circuits. Check IC1901, IC1903 and their peripheral circuits.
Do pins (12) and (14) of IC1917 become (H, L) when analog PC mode is entered?
NO
YES YES
YES YES YES
Check Pins (1)(2) of IC1917 thru Pins (8)(9) of the ME Connector signal line (I2C). Are IC1911 data accessed by I2C when connected to AV?
Are the DVI-SR/SG/SB and DVI-H/V signal input to Pins (16)(10)(4) of IC3700 (ADC) and Pins (2)(13) of IC3701 (SYNC_SEL) in the MAIN- PWB respectively?
Check MD harness for disconnection.
YES
Check IC3700 (ADC), IC3701 (SYNC- SEL) and their peripheral circuits.
YES
No picture even at DVI video input(digital signal from
A
V
unit) (3)
Check the settings: Using the INPUT
SOURCE button ( ) on the remote controller
, select
"INPUT5". Select "Option-Input Select" on the menu item, and set the input signal type (Signal
T
ype) to
"A
V digital".
NO
NO NO NO
NO NO
Are the R/G/B and DTV-H/V signal input from Pins (25)(26)(27) and Pins (28)(8) of INPUT5=DVI Connector (SC1900) respectively? Is the DVI-H/V signal output from Pins (4)(6) of IC1904 (INV)? Are the DVI-SR/SG/SB and the DVI- H/V signal output from the MD Connector (P1900)?
Are outputs at pins (12) and (14) of IC1917 both (L, L)?
Check AV settings. Check IC1911 and its peripheral circuits. Check IC1917 and its peripheral circuits.
Check IC1904 and its peripheral circuits. Check IC1901, IC1903 and their peripheral circuits.
Do pins (12) and (14) of IC1917 become (H, H) when digital PC mode
is entered?
NO
YES YES
YES YES YES
Check Pins (1)(2) of IC1917 thru Pins (8)(9) of the ME Connector signal line (I2C).
Are IC1911 data accessed by I2C when connected to AV?
