I have a vfd game that I am trying to fix, I found a blown 2sd882 npn
transistor in the dc - dc converter but an exact replacement is not easily
obtainable, I tried a tip31 but from what I can tell with my multimeter and
limited knowledge it is not oscillating, I only surmise this by the fact
that the game still does not function at all and it is trying to draw a very
high current, I have a current limiting power supply so I can safely try it
out still, anyhow if the transistor is turned on all the time it provides a
constant short circuit so I presume it is suppose to oscillate. The game
runs from 6v dc. I can find not other obvious fault.
Can someone please suggest a suitable transistor, with my limited knowledge
I have been unable to determine anything other than a tip31.
