Member: 59869 Status: Offline Thanks Meter: 132  | A1-VPP_IO not used B1-CbusSelX used ->SerSelX(RETU)&CBusEn1X(RAP3G) K3-VM_CLK ->USBVM_Clk(RAP3G)&usb0_vm(OMAP) So nothing to do with lights.The important pad of Tahvo in this case is G1(PWM300) wich has to be connected to J2309 and A2 of N2301. If you already changed N2301, then most probably the fault is L2304 wich can be easily burned on high temperatures. You're too old in forum, so I will not put links to service manuals, you probably have them... |

Member: 59869 Status: Offline Thanks Meter: 132 | UPSSS, I made a mistake, wrong counting the pins (I thought is ball view, but is top view). So the missing pads are A1, A2 and C10, NONE of them used here, so nothing to do with the lights! Sorry again... |
