What's the most frequent problem when you get a red screen???

How are you making your backups are you making 1:1 copies? Also try using different media (better quality if possible).
Check your ps2 motherboard for bridges or “cold solder joints” a dull finish on your solder means a “cold solder joint” and data doesn’t transmit as good a shiny finished solder.
Finally if all else fails try a different chip, get an original messiah2 not a clone.
