It could be a bad VIC-II chip, do you have another 64 you can swap chips with? Jay @BibBee99 and AtariGeezer. Thanks a lot for your help! Yes I have a spare C64 but that one is working and I am afraid to mess that one up. It is however not the cable nor the poweradaptor as my first step was to try the two C64 with the same setup/poweradoptor/RF-cabel. But I will try and look at the pages and see what can be done. Thanks!

Dead test card? Don't know what that is I think the A/V works. But it only shows the black screen. You know, the screen turns from flicking/noize to a black screen when I turn it on. So it does get and show a signal. It is just completely black instead of the normal boot screen.

Anyone in here who is good with Commodore 64? My breadcase is only showing a black screen, much like the one you get in between when you turn on your C64 and waits a sec for the blue Basic startscreen to appear. So there IS connection to the RF cable as the screen turns black - but not into the "blue screen" I really hope it is a typical error I can fix and sod myself ... PLEASE help.
