I recently repotted my orchid and now the leaves are turning yellow. Does this mean it is dying? Thanks?

Orchids tend to survive in the most inhospitable conditions very little water is required and that's why they are usually found in a bark like substance. they don't like too much cold , a short spell often sparks the flower stems into life, Survival is the prime intention of an Orchid Occasionally the flower stems produce small plants as against the normal flowers and with a small plastic bag with some orchid compost tied around each root ball then new plants will take off. They do require a lot of T L C and don't be disappointed when it all goes wrong.
