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
