If it is time depended(problem comes out/ disappear after some time you powered on), I would like to see whether any time related circuit is working(ex. RC time, which is ignored normally).
Actually, if you could repeat the problem, you should try to use near field probe(or high impedance probe) to find where the problem is.
Glad to share some idea. |
