CFV DB strange colors appear

[kinglang]

Hi guys,My CFV39 DB has strange colors after using flash sync mode(Large format camera),no exception when use else's 503CW with 80CFE.  The captured picture is divided into two from the middle, and the right half of the picture is shrouded in another white balance color. Take a few perfectly normal pictures, and the next second may be an abnormal picture. I have upgraded the back to the latest 270 firmware, also replaced and formart the CF card, now it is UDMA CF card.Already wiped the metal contacts with alcohol.

Has anyone had a similar problem and solved it?
