  We consider the qKZ equations based on the two boundaries Temperley Lieb
algebra. We construct their solution in the case $s=q^{-3/2}$ using a recursion
relation. At the combinatorial point $q^{1/2}= e^{-2\pi i/3}$ the solution
reduces to the ground state of the dense O(1) loop model on a strip with open
boundary conditions. We present an alternative construction of such ground
state based on the knowledge of the ground state of the same model with mixed
boundary conditions and prove that the sum rule as of its components is given
by the product of four symplectic characters.
