Anyone had their's go totally blank, still back lit but blank ? Whats likely to be the problem? No mileage displayed, or temp,or date etc. I dont own this Croma, I went to look and walked away as it also had an oil leak, scratched bumper, drivers door not locking/opening with central locking, no service history and missing rear middle head rest. I might go back if its unsold and make a daft offer but I dont want to do it without knowing more about these dash displays. Is it an easy fix? Other warning lights all working OK. Thx David (prospective Croma owner)
