    Hi,
    Lol, after all what I did with my VIC-20, it's broken... here is a pic of what I get on the screen:

    Just click on it and after click problem01.jpg

    I think it's a CPU problem... but, I'm not 100% sure...

    Someone has an idea of what it could be or what is causing that?

    I'm taking a wild guess here but it could be it's BIOS chip. Dust could be to blame too - open it up and take a hairdryer to it.

    I don't think it's dust because, it's opened and, it was working yesterday...

    Then I'm stuck for ideas. It could be the CPU, the RAM or it's ROM. There might be a specialist VIC 20 forum, most possibly in a Commodore emulation site.

    I've seen screens like this in the past with other Commodore models. It can be all sorts of things. I would try removing and refitting any socketed chips. It may be a capacitor that has failed/leaked near the power input socket. I remember the Vic 20 was available with two different designs with regards power. One had built in AC to DC conversion and I think and the other used a full external PSU like the C64. I've actually got an old colour glossy Vic 20 brochure to hand but its not helping me conjure up any other suggestions. Hope you get it working and enjoy a nice retro session. I'm aiming to have a N64 session soon.

    If your capable of it, you could try de-soldering any discoloured solder points and putting in new solder. Another thing to try is leave the Vic 20 on for a couple of hours in a fairly warm environment and then try a reset. If its a dry joint this might bring it back to life. Don't forget the computer is getting on 25 years old now so its done well to last this long.
