Let's be a bit clearer here - a reading of 00.0 on most DMMs means a dead short (you can replicate that same reading by shorting your leads together).
I've seen more than a thousand shorted horiz outputs in my life, and they all will short "hard", so if your meter isn't an autoranging type, put it on 200 ohms or 2K if that's all your meter has.
If the transistor is not shorted, then it will read the same at 200 (or 2K) as if you didn't connect the leads at all, figure something like OL on the display (means overload).
So if your meter is reading OL with the leads off and 00.0 with the leads on the horiz out, the output is shorted.
If your meter reads 00.0 with the leads open, the meter is bad.
