Reply to "TIU Help - short circuit"

You can check the four TVS diodes in circuit with a standard ohmmeter. Just measure across them, any bad one will usually read a direct short. If it's just a TVS diode, I clip the leads next to the body, heat the solder joint while holding the lead in forceps, and pull it out. You can then solder the new one in from the top without undoing a sea of binding post nuts.

The TVS diodes are bi-polar, that means they don't have polarity.
