Arcam Alpha 7 Tuner Display Issue

[Uncertain]

Hi

I'd be most grateful for any advice.

I was recently given a "faulty" Arcam Alpha 7 Tuner when I bought an Alpha 8 CD player.

Apart from one mechanically stuck preset button (which I've fixed) the only other issue appears to be two dead segments in the right hand digit of the display. This shows the selected preset channel and is a bit irritating as you can't tell some numbers apart.

Is this likely to be a duff display or a connection / dry joint issue?

Also, the case has a "take static precautions" warning. Is this just a general wise precaution or is there anything wildly sensitivity about these units?

I've done a bit of small electronic work in the past but am no expert by any means.

I'd be very grateful for any advice.

Thanks.
