3. Check MAIN CLOCK 24MHz and SYSTEM CLOCK (PLL) to operate normally after SYSTEM
operates.
☞For the first thing, check 24MHz from Y401 flows into [OSCI(PIN B18)] of MAIN
CPU
If the 24MHz is unstable, Check Y401 is damaged or not.
If you are firm belief of damage for the device, then replace the device.
☞ And then, check that 800MHz is being supplied to DDR3 with RESET
If the clock 800MHz on Pin-J7&K7 of U401 is not generated from inside of the
chip,Please check the soldering state of U401,U402 and U403
(MAIN CLOCK) 24MHz
(DDR3 CLOCK) 800MHz
