Fold display not working ( screen black - touch working)

[RohanR2000]

When I power on the device I can see the inner display works but after the lock screen pops up then the inner display goes black

Anyone know what's wrong?

It's not a display problem, is it the hinge belt?

I only want to replace the faulty flex ribbon, Samsung service centre only allows me to change the entire display which is 40 % of the phone cost
