BT Merlin Tonto screen buzzing/screeching

Hi folks, I don't think this is restricted to the Merlin Tonto (Sinclair QL remade by ICL as the One-Per-Desk office companion and rebadged by British Telecom and New Zealand Telecom) since they didn't make the monitor: http://www.binarydinosaurs.co.uk/Museum/icl/opd.php http://www.binarydinosaurs.co.uk/Museum/icl/tonto.php I dug it out of storage tonight because this morning I got a load of handbooks and manuals as well as the original BT Merlin software set in nice blue wallets, and since it worked a year ago (as you can see in the pix) and has simply sat on a shelf in the house since then I just fired it up. Machine is fine and self-tests then beeps while its prompting for the date....fine....I hit the power button on the monitor and it just screeches at me before I quickly turn it off - it sounds like the wires on the yoke ringing loudly so is it possible the poor thing is objecting to being moved in winter that it doesn't go below freezing point (and it's very dry too), but in the last couple of days here it's been in the low 50s farenheit. Anyone seen screeching monitors before?
