I bought a 29C from eBay, hoping to finally finish my collection of working Woodstocks. Good and bad news. It turns on, either in regular or program mode, for about a half second before it blanks off.
It will even hold a digit in continuous memory, so it seems it's all working but the power.
Does anyone know if this is a common problem with a single component that needs replacing, or is this a bit harder to track down? Thanks in advance for any insights.
