Hi I recently posted what I believe is the same problem maybe a little more pronounced.

I'm sad to see nobody has been able to help so far.

If I find any solutions I'll be sure to let you know.

By the way I'm French too.

Here is what I posted:

Heeeeelp!!!!!! Strange black lines partially blocking sadmac!!!!When I first got it, there was a sadmac with the error code 048545

I then proceeded to remove the ram chips and installed ic sockets.

I must have messed something else up because after replacing all the ram chips

This is the screen that appeared:

I've checked the continuity between all the ram chips. All my solder joints are good

I then changed the ROM chips with known functioning ones. Still no luck

Anyone have any suggestions????

Thanks...
