I have tried to search through existing questions to find an answer to my question, but so far have had no luck. I apologize (and feel free to flag) if this is a dupe.
I am working on repairing an arcade monitor, and I think that one of the transistors on the neck board is bad. I have removed the transistor, and am trying to test it with my multimeter. The transistor is a C3229, and the datasheet is here: http://www.datasheetcafe.com/c3229-datasheet-transistor/
According to the datasheet, it is an NPN transistor and the pins are (1)Base, (2)Collector, (3)Emitter. I am trying to determine if this transistor is bad, but I'm getting confused. Here are the readings I get in diode mode:
- B->C: 0.647V
- B->E: 0.666V
and in ohms mode (20M):
- B->C: 13.05M
- B->E: ----
ohms mode (200M):
- B->C: 1.1M
- B->E: 1.2M
And I do not get any readings if I reverse the probes. I had assumed that this transistor was bad, but it is possible that it was just a loose solder joint. Is it possible to tell from my readings whether the transistor is bad, or is there something else I can test to find out if it is bad? Also, is there a good place to find new transistors? My searching thus far has turned up a few sites that look promising, but none that carry this particular transistor so far.
I tested a couple other of the same transistor which I am pretty sure are not bad, and got very similar readings. I will assume that the problem was not the transistor.
