Sandwich one of those silly cheapo USB mug warmers into the case. Plug it in briefly for a little warmth just to get it going. Like a choke on an old-fashioned car!
Not to be a worry wart, but a long time ago we got a batch of monitors with a defective board. A capacitor overheated, melted some sort of glue on an adjacent component, which in turn dripped on a power supply component, shorted out and started a fire.
A couple of days later, it happened again… and we ended up getting all hands on deck to find those monitors.
Also good to think of alternative fixes like this when it's difficult to source replacement components.
