Hi to all and many thanks to let me join this forum! Im a newbe and im tring to fix the card in title. I have all the voltages on the board, exept 1.5mvdd amd vcore. All the resistance seems good, (i hope 3,3v at 0.209kohm isnt a problem). Searching on this forum ive found some interesting things about the gs7256 U701, and the q1604 near that. I have a low EN signal on both (0.536v), ive tryed to remove and replace the q1604 without luck, the EN always low... Tryed the cap and resistor on FB with no luck, i havent FB on both side of the r713 (i read 0.999kohm not 0 like the schematics says...) U701 pins (voltages without mvdd inductor ) 1 0,241v (9,60v) 2 67mV (9,60v) 3 158mV 4 0v 5 12v 6 1,4mV 7 0,538v 8 67mV (9,69v) Any help would be appreciated!! Greetings from italy |

Try to power on gpu with lab power supply directly to mvdd(1.5v). |

mramil Many thanks for the quick help!! I can try directly to the inductor?? Posted after 1 hour 59 seconds: mramil писал(а): Try to power on gpu with lab power supply directly to mvdd(1.5v). OMG it work!! i have all the vcore voltages, what i have to do now?? Many many thanks!! EDIT i think its normal win when load the driver show code 43 |
