This board had a few problems.&lt;/p&gt;<br /> &lt;p&gt;&#039;&#039;&#039;Symptom:&#039;&#039;&#039;The background of the game was blue instead of black and all the green snow bees were missing and just blocks the rest of the graphics were fine.&lt;br&gt;<br /> &#039;&#039;&#039;Fix:&#039;&#039;&#039; Bad N82S137N Colour Prom at IC88&lt;/p&gt;<br /> &lt;p&gt;Funny this one, In my eternal stupidness When I was fault finding I accidently put the colour prom in backwards(not the first time i&#039;ve done this either!). <br /> Ordered another prom popped her in and fixed all the problems in the game! ROFL KARMA IS REAL.&lt;/p&gt;<br /> &lt;p&gt;&#039;&#039;&#039;Symptom:&#039;&#039;&#039; No sound&lt;br&gt;<br /> &#039;&#039;&#039;Fix:&#039;&#039;&#039;Amp was fried and was around the wrong way anyway. Replaced amp with one from a scrap Kid Niki board&lt;/p&gt;<br /> &lt;p&gt;There was also a bad cap at C24&lt;/p&gt;<br /> &lt;p&gt;&#039;&#039;&#039;Symptom:&#039;&#039;&#039; No sync&lt;br&gt;<br /> &#039;&#039;&#039;Fix:&#039;&#039;&#039; Fool who made the harness wired the sync on the JAMMA fingerboard in the wrong place and no it wasn&#039;t me!&lt;/p&gt;</div>
