I am trying to repair a digital terrestrial set top box which had
bulging caps, would shut down and had no audio. changed the caps, box
works but still no sound. I discovered two small 3 legged smd
transistors (at least I assujme thats what they are) burned,
presumably due to high voltage and/or poor regulation from the faulty
psu.
The only reference visible on the components is a '2'. In the same
pcb there are others marked '2A', so i'm assuming these two might be
the same.
They are on the pcb as Q5 and Q6, and the pcbitself is maerked: HY650
39150 DST VER 1.7 (2004) and it has the Zoran supraTv chip
Now I know these are disposable items, but I don't mind investing a
bit of time and effort trying to fix it, as it doesn't owe me
anything. I'm all ears as to suitable equivalent parts.
TIA
