MY MVS have a problem!

I have a JAMMA video monitor connected the Neogeo-MVS (MV1A), when I power on , blue screen is appear and some message is prompt out....
it prompt
Color RAM error
checksum read is AAAA
checksum write is AAA0

Someone can help me to fix it??

Yes. The lower 5864 color RAM is bad, or you have lifted pins on Neo-b0. Be careful and take that to someone else for any flatpack rework if you are not able to...
