my ZX-Uno seems to have a problem
![Sad :-(](./images/smilies/icon_e_sad.gif)
It worked properly for weeks, I made no update, only put it away for some month.
Yesterday I wanted to play a little around with it but the screen was black on bootup.
Then I tried composite with no success. But when I connect a joystick to it, press the button and up on startup, I get a Screen that tells me "ZX-UNO Spectrum core is loaded. Now trying to boot from BIOS..." and "You shouldn't see this screen for more than half a second".
That's all, nothing more happens. What can I do?
Thanx for help.
