Of course it's repairable. But it's a question of how long it will take to properly identify the root cause of the failure, then find and obtain the necessary part(s), then install it.
But the G70 is definitely worth fixing. Do you have previous experience with CRTs? Unless you're looking for a challenging project, you might be better off selling it and looking for something functional.
What condition are the tubes (look through the lenses with a flashlight, or better yet, remove the lenses and post a picture).
Where are you located? If you're not the fix-it type, maybe Curt or someone else with a G70 could work out a trade towards a fully functional projector.
