<p></p> <p><b>New page</b></p><div>Repairer: Tandgnissle&lt;br&gt;<br /> Game: Twin Hawk&lt;br&gt;<br /> Symptom: Dead (seller claimed no sound)&lt;br&gt;<br /> -------&lt;br&gt;<br /> Upon powering on the PCB was dead, thought I saw a faint glow from a Zener diode.&lt;br&gt;<br /> Measured resistance on power rails, found dead short on 12V.&lt;br&gt;<br /> Disconnected 12V from power supply and game works without sound, power supply over current protection had kicked in.&lt;br&gt;<br /> Desoldered D2 Zener diode on the 12V rail and measured it, dead short in both directions, 12V no longer shorted.&lt;br&gt;<br /> Replaced Zener diode with a new 16V one and sound now works.&lt;br&gt;<br /> <br /> [[Category:Repair Logs]]</div>
