I wondered whether that was possible but I don't think the inside got 
anywhere near reflow temperatures - the only heat damage was that bit of 
SRBP like stuff and the foam behind that looked much the same as 
everywhere else. It probably did get above 100deg C for a while.


I'll give it a thorough clean and have a close look at all the joints 
and SMT components when I have chance.
