Answer
Sharon you may just need a good shot of fertilizer as trees in the sun tend to use more fertilizer than those that arent.  There are many nutritional elements that change as a result of more of less light.
You may also need a plant enima as your problems could be systemic.  Bacteria or fungus may be blocking the flow of nutrients for proper growth and greenup.  

I have been using a product on Sagos for about 8 years now called Atomic Grow.  Its a foliar spray and will make Sago Palms look amazing.  It will remove scale too.
