I recently upgraded to the HS20 Great pj, like the pic a lot, no screendoor, great colurs etc BUT.... The colours aren't properly converged When I put the focus grid on, the white crosses are fringed with colour. The effect is exactly like on rear projection tvs before you do the convergence adjustments. Is there some way of correcting this via menu or service menu? Should I have to do this? I bought it 'ex demo' from Sound and Vision, should they be responsible.? This MUST be affecting the picture, has anyone else seen this effect?
