I am giving my Sony CRT to my parents but they might not be able to take it right away. Would it hurt to store it in a detached Minnesota garage during winter months?

thanks,

I would wrap it and put it on something other than the concrete floor(floor tends to be diff temp than air-- cause condensation/wetting?). Should be okay. When it comes back in for use, let it acclimate for 24hrs because that cold bugger will get wet in the warmer air.

Yes, I would set it on something to get it off the floor.

I am a bit leary of a CRT sitting in -20 degree temp. I wonder if you have any Sony CRT TV manuals that tell storage temp range? At what temp does CRT glass shatter under it's own weight or internal vacuum?

FWIW.....
Does anyone REALLY know how cold warehouses that store(d) CRTs actually got/get? Here in central NH, the local CC has unloaded CRTs from a semi into their unheated warehouse in the dead of winter...without a thought to temperature.....then loaded units into the back of customers' vehicles -- equally unheated!!:eek:
IMHO......the cold won't do your unit much good....BUT...IF you MUST store it under these conditions.....the advise to wrap it and KEEP IT UP OFF THE FLOOR (on a pallet and/or cement blocks) is dead on!! AND....BE SURE to let the set warm to room temp AT LEAST 24 HOURS BEFORE APPLYING POWER!!!!
Many years ago, I bought an RCA XL-100 16" from a local dept. store....and left it in my car -- in a New Hampshire January -- for 5 hours. When I got it home I unpacked it, plugged it in and fired 'er up....well....it worked ....for about 5 minutes...then...SSSSSSNAP! No pix! (I later found out it was a "fried"/"frozen"? high voltage rectifier....). It was after this episode that a local service guy gave me the word to let sets come to room temp before powering on....)
Good luck with your situation!

I think air pressure lowers as it gets colder, so tube implosion shouldnt be a problem.
