Please Help...Asus K43SD Rev 4.1 no detect HDD and ODD, sata issues..

[G11NS]

Asus K43SD Rev 4.1 can't detect HDD and ODD at BIOS or system.
HDD power won't turn on (+3vs, +5vs on hdd power ready, but the hdd still off)
ODD power is ok, but didn't detected.
tried to change with any HDD , only 1pcs would turn on (spinning) but still no detected.
usb port no problems.
Replace intel HM65 chips, change sata port, still same issues.
Does anyone can help me...please??

CHECK THE +12VSUS IF it's less than 12volt for exemple 10volt or 9volt replace the system regulator pu8100= rt8206A and chek again after replacement. i think if you have a lab power supply you can inject 12v (50ma) at pjp8105 and you can check the hdd detection in bios; before wasting time for relacent of ic.
here the picture of pjp8105 .
