alltough works well on battery , just like the bloody nec problem , meanwhile i replaced the 6 tantalum capactiros , as also replaced the vcores fet for news ones , since they were allready with a arsh color .
lets see later on the final test
I have not seen one of those yet. Have you checked the Vcore rail for ripple?
Some types of ceramic capacitors do lose capacitance with time. Its called "ageing".
