I have what appears to be a thermo intermittent problem in my old TV. I'd
like to buy an aerosol can of freeze spray online to help track down the
problem. I'm looking for recommendations on a brand and a vendor. No body
carries this item locally. Thanks.

Did you try Radio Shack? "You've got questions, we've got C-students in
ties." They won't know what the hell you're talking about, but look
around yourself and you'll likely find it.
