Hi there and welcome
If it is the Frame itself it will be the mainboard that has failed as all the components including power supply are integrated onto this. They do not offer to replace this unless it is covered by warranty, the reason is the mainboard is most of the value of the Frame, and hence it would cost more to repair then the value of the frame.
Is it though still under warranty?
ok, then you'll need to purchase a full replacement, as I mentioned the cost to repair this is not worth it which is why no one offers it.
The cheapest I found was here
I advise on the extra $10 for new as opposed to the used products.
