Hi and welcome to the forum. It sounds like all the electrics are working for it to get that far. It's possible there's not enough hydraulic pressure to get the roof beyond the 1/4 point - I'd be checking the soft top motor for water damage. There are several members here who can repair/relocate the motor depending on where you are.
Also possible there's a leak in the hydraulic lines causing a loss of pressure. Are you able to feel any seepage on the lines, or see any evidence of fluid leaks?
Best of luck, this is not usually a huge problem anymore with the depth of knowledge, experience and expertise on the forum. Someone should be able to help you out.
