salam alekm

i had wd800bb 00fja1 pcb 2060-01130-012 strange problem first the hdd was knocking in strange noise i remeberd that ms pepe said check rsistors before motor points so i did and i found it different from defult
tehy are 3 resistors their defult is 2 k ohm for each and in this pcb 2 of them was only 1 k ohm and third one is 2 k ohm so i checked the controller ic it gives short between 2 legs there is no short between them in defult so i changed the ic and every thing become good all are 2k ohm and all ok i tested the hdd it works good for while then when making scandisk it starts turn off and on every few minets so i checked the resistors before motor again i found them come down from 2 k ohm for each to 0.6 kohm for each and the short between the same 2 legs in the ic is back so plz help if any one saw this case before
