Also it is not a ‘conversion’, it is a SF2CE upgraded to HF with 3 roms
Also check if the A board is 12MHz as it lacks the ‘dash’ sticker

Most likely bad graphic ROM (stuck data bit) going by your picture.
you refer to the 3 roms that were used for the upgrade?
or others?

Probably just one is bad. Identify it by pulling ROMs one by one.

Each time you're going to pull one a new graphic problem (16 pixels or so vertical bars) should appear. When those bars cover the initial fault then you've found the culprit.
If you're inexperienced you should still check all ROMs to be sure.

I'm not sure we ruled out the c board as bot being the problem. Was the known good replacement c board a cps-b-21? Sometimes the custom chip part number is under the street fighter 2' sticker. But it needs to be a known good cps-b-21 c board.
The C board is responsible for graphics. If it's faulty or not firmly seated that would certainly explain the lines.

Bad or dirty connector, damaged trace or via, cold solder joint in one of the chip's pins, bad chip...

If the type of Bxx chip in the c board matches (e.g. B-21) then they are compatible and should work fine.
Nothing bad will happen if you use the wrong chip. The connections to the B board are always the same, regardless of B and C board types.
