I opened a spare and pretty much wrecked the lid.
haha my lids still intact i have just wrecked the lip around it but nothing a good sealant wouldn't cure once i'm happy with the inside it will never be opened again
still not sure it is the problem as the contacts which are suggested to solder all look good and in contact still
tshirt - can you see a visable defect with the solder if there is a problem when you do it? cheers
