French NES broken - how to get repairs?

[ZDragon]

Hi people,
I am the owner of one of those nice French NES consoles that have a full RGB output. You can guess that I tresure this piece of hardware a lot. However, I recently had to discover that the NES no longer turns on. At first I had the standard blinking issues, which I fixed by cleaning the game module connector. Afterwards there was no more blinking - but sadly there is also no image or sound at all now. Just a few white dots on the screen for half a second when I turn the console on or off. I don't think that I have made any kind of mistake while cleaning the connector, have tried putting it in and out numerous times now, however with no luck.

I know that fixing such a problem over the internet seems somewhat helpless; however, I just don't know where to turn. I'm living in Germany btw. Anybody know a place that I could bring this baby to for fixing, or any ideas on what might be wrong with my NES?
