Re: Barco LCN-42 No Power
That is why I built a fume extractor after 35 years of sucking up the solder fumes, I use the bath room venting fan and got the charcoal filter and a light dimmer for controlling the speed. Ah, there is nothing like the smell of solder fume in the morning!
Oh, where was it again?
I sure like to know who generated this darn VCC.
I will have to look at NCP1377 data sheet again to remember what it is for.
Good job for finding the short, Jasgriff.
Oh by the way, you put that jumper back in place that I had you remove to find out why we lost the VCC? I would also leave the MOSFET out this time. And the two transistors and resistors you replaced are still good?
That pin 8 is the kick start pin, so I would think some kind of power connection should be there to kick start it.
