Fans have complained to the County Board, but nothing can be done to remedy the situation unless the Planning Authority accedes to a request to have it repositioned on its original site at the Caherdavin end of the ground.
Board chairman Pat Fitzgerald said the local authority had co-operated with them through the planning and building stages, but it was felt the scoreboard would not be pleasing to the eye on the main road from Shannon to the city.
The county board, he said, was losing out financially because of the decision.
Before redevelopment, they were able to sell advertising space on the back of the scoreboard, which provided valuable income.
Limerick had hoped to put advertising signs on the back wall of the stadium but were turned down.
Mr Fitzgerald also claimed that TV cameramen had difficulty in focusing on the scoreboard in its present location.
