Ok thank you, what could cause that problem? Is that 12v line? |

this is a steering cirсuit. burn is not a rare malfunction. perhaps due to an incorrect time delay when opening the transistors, a counter current occurs and one of the mosfets burns out. |

Okey i have a lot of that mosfets, but PCB is too damaged to put it back only, i think that q501 is fine. I don't know where is the gate for that q502 cause is burned and around q502 in red circle is missing one of the resistors and it don't have traces to solder. Source and drain for mosfet is easy to rebuild but that gate and that resistors. Also I don't know their values and value of c501. Could someone help? And when I looked more in PCB there was no q532 and capacitor and resistor i soldered 7002k but I don't know I'm right and dont know values of capacitor and resistor. Thank you guys, I want very much that card because it has nice cooling system and it's looks great :) |

I think that is 12v line so guys, can i bypass that mosfets? just straight connect 12v directly |
