Hello, Try disconnecting the primary of the transformer and see if you still see the hot Q2. Better still would be to monitor the current if you have a meter. Sounds like you have a bad transistor though You should also be able to check for a Drain/Source short using a ohm meter with the primary dis...

Is the transformer connected into the circuit? I had a similar problem and found a short on the PC Board foil pattern.
