Reinhard,
If your console was displaying dashes in place of some of the weather data, and if a flashing "R" was at the bottom right corner of the screen, then it's possible your console was getting some frequency interference from another device somewhere, such as an older 900MHz phone or a baby monitor, etc. What you described happened to me and, after trying many many recommended fixes without success, all I did was simply move my console 5 inches and my console came back to life for good. And that was months ago. That was one of the recommended fixes I had read about.
My point is that, quite possibly, when you moved your console to dissemble it, you might have moved it away from its interference and revived it that way.
