Step8: Check flash programming reliability. Check all video inputs and signal quality. Check DDR memory reliability. Check power ON/OFF, cold/warm reset stability. Check the low voltage(1.7 V)/high temperature (40 degree C) environment test. Step9: If you can not find out the reason of trouble, we advise you to change the PCB. - Page 14 The circuit diagram LX_VCC_33 LX_UART_TXD R283 R285 LX_UART_TXD 20 C3001 C3002 C3003 PCI_33 12pF 12pF 12pF LX_UART_RXD R284 R286 LX_UART_RXD 20 CN3001-1 CN3002A COMPONENT 1 AUDIO R3001 4.7K Y 1_R GND1 SIG1 3.3V_SB CbPb1 R3002 4.7K Y 1_L GND2 SIG2 CN3003 R3003 R3004...
