Part 2 of the BM786 troubleshooting repair, proving it's the processor at fault.
And Dave goofed up BIG TIME, did you spot the ERROR in the previous video?

Is it possibly telling you that no probe is plugged in?
love to the other ausies
no thats the sign off an ace stay cool
shame on you 4 seing that
looked like one though , cool
wait hpne 4 a beeer be back loojs cooool
As for the InErr, is it possible that since the processor from the donor board had a different resistor, that perhaps that resistor needs to follow the processor to the fix board?
If mem serves, the fix board had an upside down 0 ohm resistor while the donor board had something like a 1K ???
Perhaps the mod was for a slightly diff. proc chip!???
Hi ,
Sorry , I was looking out for you !! I thought you’d be following Virgin Orbit flight? Ohh well.
Sorry I didn’t know where to post, so I snook in here😳😁👍
Exelent video series, tks 🎩 Mrs. Jones,.
part 2! yay
Great work.
Why did you sssume that "InEr" = Insertion? It is Initialisation, obviously. As far as I cam see, you soldered the chip poorly, some pins are probably loose.
very nice repair video 🥳 I just purchased a cheapy $57 HoldPeak_HP-770D CAT III Auto Range 40000 Counts DMM BarGraph MultiMeter, seems to work OK on hobby stuff?
Now for the important news. April 20 2023, 11.27am local time, Total Solar Eclipse over Western Australia’s Coral Coast. Are there any venomous snakes out where the tourist will be?
Perhaps someone jabbed a 2.2K where a zero Ω belongs? Ron W4BIN
When you make electronics videos you're great!
Теперь все знают , что чип это Stm32.
A whole lot of useless components. It's time to make something with a normal color TFT LCD with a built-in electronics and a lot of measuring modes. In the same space, it is possible to integrate a signal generator and signal logger with 10x precision with internal calibration tables – there is no problem with built-in memory for that nowadays and normal MODERN multimeter functions, not defined by marketing, such as L measurements with low current milliohm meter. Like what is the problem ? It is solvable by modern integrated circuits.
Honest to god, Dave, I was convinced the other QFP was the processor roughly half-way through the last video, simply by the huge number of traces going to it. I never commented on it as I'm not an electronics engineer and didn't want to make a fool of myself, to be brutally honest with you.
Diodeb D7 is broken🙃
Brymen should release firmware updates to public!
I have never seen you fix anything. You need a better more logical fault finding approach perhaps.
Good work.
Could the Insertion error be a false alarm related incorrect DMM input jack connection?
Take a video about this , The world is now ruled by one community of people, the world Satanic elite, you can also call them the committee to meet the Antichrist and prevent the 2nd coming of Jesus, Trump called them the deep state, at the moment it consists of about 10,000 people, the main ones there are Rockefellers, Rothschilds, Windsors, Baruchs, they, their ancestors, descendants and other people who enter there have the mark of Lucifer, which, if they bring the antichrist and do not allow the 2nd coming, they will receive eternal life after the x hour, and the rest of humanity, for all the time that they have lived, they won't get anything, They won't stop themselves
1st of all, an multimeter it’s the main tool in EE lab. You should purchase a trusty piece of equipment and not “Made in 3rd world” POS. OK, your budged is very tight, then buy an 5 – 20 bucks DMM, save money and buy a trusty equipment designed/made in normal world.
Otherwise you will spend more time in troubleshooting the multimeter than the real problem… Think twice and buy a quality product like Fluke, Keithley, Keysight, etc.
Can you trust the EEVblog branded DMM? Even the creator(??? I doubt he even know the design…) / sponsor doesn’t have the schematics !!!
Is Brymen better than KAIWEETS? …the same crap, only in different package, and the price is different 🙂
