Is it possible to repair a switch?

Question

D-Link

Hello, I found here an old long switch, for 8 ports. I decided to check the lan with a tester, I connected it, on the lan tester 3 lights do not light up, it is the same on all ports, 3 do not work. Can it be done somehow? or throw away?

Vryatli himself. Yes, and it is not worth the hassle. But in the service they will be able to fix the length.
On the site dlink.ru you can see the addresses of offices.
