Using magnification, check that the solder around where the quartz crystal is connected, isn't lose. Sometimes it comes lose in that area on the Sanyo's. I found several of these modules years ago and half of them were dead. I was unable to revive most of them, even with a new QC...Which aren't easy to replace on these. I wish I had them today, since my repair skills are more improved but I think in most cases these modules die easily because all the guts (main IC, etc, etc) are right under the batteries. Any little bit of leakage and it's game over.
