Sanyo ds31590 picture's very dark and red

sounds to me that your picture tube needs rejuvenated.
You will need to get it done by a tech.
mechanical doesn't mean a thing when it comes to electronics.
Mechanics when working on electronics, end up costing more damage when you end up taking it to a tech.
