Im working on this model Hp 6550b 6050A2326701 (Diesel 10)motherboard and the 3.3v/5v is switching on and off constantly I have found that Q11 is being switched on and off (Entrip 1 and 2) causing the regulator to output and then stop in a cycle. I have replaced both Q42 and Q11 but still the same . I have also replaced the SIO. Any help appreciated. |

Is there any progress with it? If not, remove Q42 and start mobo without it, then measure voltages in its pads and post results. |
