Look for dull, broken, or ringed solder joints(particularly around the battery terminals and the big copper antenna coil). Resolder Connections: Using a fine-tip soldering iron, thoroughly reflow the solder on

     any suspicious connections. Include a tiny dab of fresh solder if necessary to ensure a solid electrical bond. Clean the Board: Wipe away any particles or old flux with isopropyl alcohol.
