Hi everyone, i have bought this Fluke 73 series 1 but it's not turning on, I can't find schematics for the series 1 i have found only series 2 and 3, and based on that i have tried the test points and i got wrong voltages, is there any way to fix it! it got some corrosion that i cleaned but no luckScreenshot_2026-11-08-22-31-26-559_com.miui.gallery.jpgScreenshot_2026-11-08-22-33-07-183_com.miui.gallery.jpgScreenshot_2026-11-08-22-33-16-909_com.miui.gallery.jpg

I don't like the looks of this. Is it really broken off as it appears in the photo? Whatever that chunk is seems to be directly opposite the multi-pin chip on the other side of the board. Is it maybe a heat sink of sorts?

and what exactly is that supposed to tell us? you measured what, where using what and got what result?
how does it behave when you power it on? any sign of life? anything on display?
