The compass platform was hit, not the CT or DCT, and PoW's firing was unaffected by this hit.
The compass platform WAS in the command tower. Jeez !
"The situation was becoming tense on board the Prince of Wales; at 06:02
, the Bismarck fired her eighth complete salvo from 14,000 meters and hit the British battleship on the command tower (compass platform)
, the shell passed thru not exploding but killing almost all of the men within(47). The Prince of Wales ceased fire(48)
. Luckily her Captain, J.C. Leach, was still alive and, after a few moments, desperately worked to bring his ship out of that dangerous position. He completed the turn around the sinking Hood and started an evasive manoeuvre, turning to port to disengage."
From the salvo plot it can be seen that, after firing 2 salvos at 6:01, (4 + 4 shells), PoW only fired again at 6:03, and than with only 2 shells
. Than only 1 shell at 6:04 and another shell at 6:05.
