Whoops meant to post this in the Export radio section.

Here's a fun one! First noticed this issue in my car a while back in some cold weather but had radio inside after that so wasn't an issue. Been using the radio in a unheated shop recently and noticed that if the temp is below 60 or so the radio display acts up. I can aim a heater at it and the display starts coming back but as soon as it cools off again the display goes out. Everything on the display works perfectly fine (once I can see it). :) I think this radio is 5+ years old now and was used heavily in my mobile it's first 4 years.

It occurs with LCD displays in watches - vehicles - lots of stuff.

Per @sp5it - it pretty much causes the dropout.

Eventually moisture kills the rest of the display - so best to use a "warmer". Helps drive out moisture and warm the LCD crystal so it can twist more effectively.

The plates of the LCD and it's material sandwiched in between - there is a polarizing filter used to show up the polarization effect of the windows to the crystal twist in the display - darkening the element.

The HR2510 used a filament lamp - but too much heat can do he same results - permanently darkening it from too much heat - so work accordingly.
 
Hmm I have a little 12V aluminum heating element (similar to the one pictured below) - maybe I can mount it on the case towards the front and it will radiate enough heat to warm up the display and keep it on.

It gets pretty warm so wouldn't want to mount it directly but maybe nearby would work.

Maybe I just need to hold on to the radio long enough till I move back to Hawaii, then everything should be fine :)

I went surfing in 35 degree temps today so I can relate to the radio experiencing shrinkage.

Fading with temperature is normal for perfectly working lcd displays,
That's why some Whites detectors have viewing angle adjustment to restor contrast in low temperatures,

The same effect but more extreme happens when the conductive elastomer gets contaminated,
missing or faded segments is the only fault i ever found on a Fluke dmm & very easy to fix,

I strip & thoroughly clean the edge of the glass & the rubbers & the pads on the pcb with 100% dry isopropyl alchohol, no touching with bare fingers & reassemble.

works every time for me.

Maybe you could put a night light bulb under the radio and just leave it on all the time? Or maybe an IR heat lamp on a lamp timer pointed at the top of the radio? Or maybe put the radio on a heating pad on a lamp timer?
