Your Mistakes

  1. your function is not called
if(grid[m][n]=='O')

        solve(0,0,grid,soln,m-1,n-1);

correct Condition to check is
if(grid[m-1][n-1]=='O')
	    solve(0,0,grid,soln,m-1,n-1);
  1. if(i+1<n && !vis[i+1][j] && a[i+1][j]=='O'){
    this is incorrect
    correct condition will be
    if(i+1<=m && !vis[i+1][j] && a[i+1][j]=='O'){
