As much fun as it was to do TV repair fault finding, it is equally fun to do SMPS repair.

Since there was no current going through the bridged over collector-emitter at all and made the Fan powered on at maximum speed all the time.
The number of smps units you already saved and gave a second life must be enormous by now?
