I think my huge ficus plant is dead - help please

[Luxurybeliefspreader]

I have had my ficus for about 6 years, it's in the same spot it's always been and I've done nothing different re watering than I always have but in summer I repotted it to a bigger pot, it's about 6 ft high.
Ever since repotting it has failed to thrive and now every single leaf has fallen off/ shrivelled and died.
I know they shed leaves but it's never been like this.
The roots I can see on top look like they always have but I haven't tried to lift and look underneath.
My other ficus I took from cuttings are thriving.
I have trimmed it back and the thin little branches felt quite bendy rather than hard which I thought might be significant.
Do I keep it and hope it will revive or is it dead ?

My guess would be that it’s not been getting enough water but a picture would help. All the food transport is done by a thin layer just under the bark. This layer should be green. If you take off a tiny sliver of bark and see green underneath, that branch is alive and may reshoot.

Ace thanks I'm not at home but I will take a look and post a picture.
