It did not. What am I connecting with the bodge wire? L801 B directly to R838 B? |

This certainly explains some of the inconsistencies I was seeing in the measurements. That looks ugly. It will take some scraping! And at some point perhaps you should replace both of those resistor, but for now you need to see if anything else is causing this or the scope was just used/abused a lot. |

You tried resoldering? I see at least two solder joints that look toasted. The left side of R839 is not looking good. If you can't get a connection and just want a bodge for testing now, then yes just replace the trace with a wire, from that burnt side of R838 to the left side (near the resistor symbol) connection of L801. |

The pads for R838 have completely lifted off the PCB, explains why resoldering didn't fix the problem. I guess my next step is to wire in two bodges, one to L801 and one to D2? |
