Issues with VT420 (was Re: LK401 Keyboard)

I suspect there is noting for it but to open it up and check the power supply. Should it be necessary I have a small supply of flyback transformers, but I doubt it is that.

The terminal arrived today but unfortunately it doesn't power
on. I've checked the fuse and continuity of the cable, fiddled with the
contrast, etc. It doesn't do anything, not even a self test. The
terminal is completely silent, not even a transformer humming.

I have contacted the seller, but if anyone has any suggestions about
what might be the issue, please let me know.

Thanks all,
