Re: Insignia NS L42Q 10A
I see, budm. Makes sense. Thanks for the info, I didn't think about cross-model board usage with component differences.
tom66, yeah, I wouldn't feel super comfortable trusting a "working pull" like those unless it was dirt cheap. |

Re: Insignia NS L42Q 10A
I need to locate my better multimeter, or go borrow one of my father's many. I just don't trust this one I have here.

Re: Insignia NS L42Q 10A
Hey this thread was very insightful, I just picked a this model up off of craigslist for FREE
 and knew I could find something here on badcaps, I'm going to test the fuse and the two caps (are they filter caps?) on the t con, I think the t con in this unit may be newer? i'm not sure, but some of the chips look a bit different, I'll post some picure of it later on. |

Re: Insignia NS L42Q 10A
Yes, you can look for shorts uisng the Ground plane of the board for the meter probe and just move the red probe around the board start with the caps, especially the MLCC type.
