Mfd screen gone dark

Hello,
I searched around and hopefully I am not posting a question that has already been discussed. I have a 2005 Prius working like a champ at 131000 but the center screen has gone completely dark. It worked off and on for about a week before it stopped turning on completely. Since I can control most everything from the wheel I don't want to spend the money to buy the expensive replacement (cheapest I found online was about $140) but has anyone had luck repairing their existing screen with similar issues? Thanks for any info and have a great day!
Brian
