Check operation of each device.
(AMP source : BD / Video input of player : 480P / Connect the TV.)
Check operation of U1001.
Check operation of U1302.
Check operation of U1501.
(18) Check power supply.
Is 1.8V supplied to C1019/C1053/C1037/L1003?
Is 3.3V supplied to C1112/C9032/C1124/C1122?
(19) Check xtal oscillator.
Is there 28.6363MHz oscillation of X1001/X1002?
(23) Check xtal oscillator.
Is oscillation of X1301(27MHz) transmitted to U1302
(155pin/156pin)?
(20) Check RESET.
Is RESET waveform conrmed in U5500 (53pin), when power is
turned on? (If continued to "H" or " L", proceed to "NO".)
(24) Check RESET.
Is RESET waveform conrmed in U1301 (4pin), when power is
turned on? (If continued to "H" or " L", proceed to "NO".)
(27) Check RESET.

turned on? (If continued to "H" or " L", proceed to "NO".)
The pattern and circuit from the HDMI connector (K1510) to the
IC(U1510) is defective, or HDMI output circuitry is defective (U1510
and surrounding circuitry).
(21) Check output signal.
Is waveform conrmed in R1063 (IPINDE/IPINVSYNC/
IPINHSYNC/IPINPCK). (If not continued to " L", proceed to "YES".)
(25) Check output signal.
Is waveform conrmed in R1312(1TXDE/1TXVSYNC/1TXHSYNC),
R1309(1TXPCK). (If not continued to " L", proceed to "YES".)
(22) Check power supply.
Are 1.8V or 3.3V supplied to U1302 (each power supply pin)?
(26) Check power supply.
Are 1.8V or 3.3V supplied to U1501 (each power supply pin)?
