first I found an electrolytic capacitor (EC28) 1000uF / 6.3V swollen side DIMM2 memory slot. Replaces the condenser. Yet the board is not turned on. I began checking for a short in the secondary voltages and found the VCCS_SB sign with resistance 0.9R. If I can apply a 3.3V voltage at this point of the circuit to locate the defective part? Posted after 3 hours 1 minute 30 seconds: located hot component, Integrated U9 (MS-8520 7G) . I try to make the replacement of the Integrated. Posted after 54 minutes 35 seconds: replaced U9, board returned to work but now chipsul begins to warm enough without raising video. Is it impossible to repair the motherboard by cost and lack of components and material to replace chipsul. Abandoned repair the motherboard. |
