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. 

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:

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. 

Two questions:

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. 

2: What is that burnt part and where do I find a replacement?

As always, many thanks in advance,


Chad
