Panasonic PT-LB20VEA convergence problem

I bought a projector which needs fixing.

It's a Panasonic PT-LB20VEA.

Done 357 hours apparently but was so incredibly dusty inside, I would say probably more.

Have done a DIY deep clean of all light tunnel and lense, fans, case etc.

The original reason for needing fixing is the convergence offset which is easily apparent.

It looks like horizontal on both blue and red, maybe green too, but not 100% sure.

Looking at the optical block, there is no obvious means to remove the LCD's and clean them, and the polarising filter before the prism, nor adjust convergence.

Any tips would be welcome?!
