9. DVD Part: Introduction of MTK1379 maintenance Under normal power supply conditions, the maintenance plan for MT1379 mono-chip is: first the reset circuit resets the MT1379, after the crystal oscillator circuit gave the clock signal to MT1379, MT1379 will start the initialization check for Flash、E PROM、SDRAM, after everything is checked to be normal, it will start initialization check for 7Audio DAC, MT1336 and motor Driver. - Page 14 MENU TV/AV TJC3-2Y AV1-VIN AV1-AL AV1-AR CNS01 RS01 CT01 CNB02 RT02 RS03 CNS02 RB04 RB03 RB02 RB05 RB01 CNB01 1.8K 1.2K TJC3-2Y CNT01 TJC3-10A A6-5V R208 A6-5V N202 R278 R222 R212 R211 R215 24C08 CN704 CN200 A6-5V CN703 3.3K 3.3K 3.3K 3.3K 3.3K...
