<DIV><FONT face=Arial size=2>Excellent. Thanks for the response. Do I need to
remove the ICs or anything? I imagine the socketed components should go, but
what about those soldered to the PCB? </FONT></DIV>

<DIV><FONT face=Arial size=2>Also, what do you make of the burn? </FONT><FONT

<DIV><BR></DIV>If it's soda, then the best way to clean the PCBs is to totally
remove them from the synth and run them under water. Distilled water is
best, but generally tap water works just fine. You can just run them
under the faucet, or use the shower in the case of larger PCBs. You may
want to follow this with a rinse of distilled water.<BR><BR>After this, follow
up with compressed air to dry it if possible. You particularly don't
want the water to stay in the pots and switches. <BR><BR>Alcohol won't work
too well with water based spills like soda or beer.<BR><BR>Tim<BR><BR><BR>Chad

<DIV><FONT face=Arial size=2>I just received an SH-101 purchased over eBay,
which was advertised as "not working". The problem, according to the seller,
is that it simply does not power up. This was confirmed upon unpacking and
plugging the unit in. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>So I take the unit apart. Look over everything.
The first ominous sign is that the PCBs are soaked in soda (well, perhaps
not soda, but something that was once a liquid but is now a sticky,
brownish semi-solid). The second ominous sign is a burn near one of the most
soda-soaked areas. Pics here:</FONT></DIV>

<DIV><FONT face=Arial size=2>There are a few other curious-looking anomolies
which could be causing problems, but these two issues appear to be most
worthy of my immediate attention. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>T</FONT><FONT face=Arial
size=2>wo questions:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>1: What is the easiest way to clean these PCBs?
I tried isopropyl rubbing alcohol and q-tips, but this was proving to be a
tireless endeavor. It would take about 20 hours at the rate I was
going. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>2: What is that burnt part and where do I find
a replacement?</FONT></DIV>
