Hey friends

I have another MV-1FZ which will pass all tests on the Diagnostics Bios after I replaced the Fast VRAM.

I have those black vertical lines so I thought it might be LO-ROM related. So I removed my LO-ROM and put a Socket in and tried another LO-ROM with the same results.
I also replaced the LS245 that connects to the LO-ROM and continuity from LO-ROM to LSPC2 and LS245 seems all good.

Along with that I replaced U1, U3, U4, U5, U8, U13 - same results.

I resoldered the Cartridge Socket pins and the LSPC2-A2 and the NEO-B1 along with some other ICs.

Any hints for me from people who has similar issues ?

Thanks have a great sunday
