Amiga 500 Rev 6A Video problem #52

Closed marcob1971 closed 2 years ago

marcob1971 commented 3 years ago

Hi all, on my Amiga 500 Rev 6A, normal denise, raspberry Pi Zero W v.1.1 the video appears with incorrect colors and there are also colored bands similar to interference. I've tried different types of setup but nothing change. Any suggestions? Thank you.

You either have damaged input pins on your Raspberry Pi, or someone has made a very poor job in soldering the adapter. Looking at this image, it seems that the signals B0, B1, B2 and G2 are low all the time and G0 is fluctuating randomly. You could try to give the ICs on the adapter a very close visual inspection and watch for missing solder or solder bridges. Trying a different Pi is another option.

I will try to check the missing solder or bridges because I have already replaced the Pi. Thanks c0pperdragon.
