I have picked up this meter, in decent condition for $20.
It seems like, it is completely dead.
Fuses and battery are good.
After opening, I have found some transistors looking components that are shorted, but not completely. At one of them, it seems like the green paint came off at one leg and in the same spot, seems like the trace has a damage as well(maybe missing transistor leg, hard to tell).
I'm not sure what they are actually to properly test them.
They have a JC marking on them, thy could be some kind of diodes?
I can't find schematic for this meter anywhere.
I have also noticed, that the two PCB trace circles(buzzer contacts) are missing, even the traces leading to these two pads are not reaching the circles.
Another thing that I have noticed, that one of the traces that goes through a via to one of the LCD LEDs is missing. Between resistor and LED.
What could have happened here?
I have not taken any pictures yet, but I have found some picture at the eevblog.
