That transistor is in parallel with other (adjacent) transistors. I'd suspect broken traces or pulled vias if it reads shorted and the others do not.

[bigpun4fubu]

vias?

[bigpun4fubu]

the 3 in that bank read 0 ohms across legs 2 and 3

[Perry Babin]

Vias are the copper feed-throughs that connect the traces on one side of the board to the traces on the other side of the board.

Are either of the other two shorted? If not, there may be an open connection between the drive circuit and the gate of the FET that was preventing the FETs from switching off.

[bigpun4fubu]

all 3 read shorted in circuit

[Perry Babin]

Are all 3 OK out of the circuit?

Did you check the ones on the other side?

Many times, when you have parallel transistors, you can find the shorted one by measuring the resistance from the gate to the drain. The shorted one will read lower resistance than the other ones.

[bigpun4fubu]

the other side checks fine , here is Q203 of the bank what it reads out of circuit, will post other 2 as well

[bigpun4fubu]

Q204

[Perry Babin]

These are OK. If the 3rd one is similar, it's also OK.
