Unfortunately, I think you're going to be correct re longevity. In some ways, you might expect flat panels should last longer than old CRT displays did, but that hasn't generally been the case so far. Hard to say for sure though, as technological "obsolesence" has been occurring sooner so we often voluntarily replace. In general, it seems people don't keep anything as long as they used to.
Why I mentioned the cold spray is it could help detect poor solder joints. I recall reading several years ago that they were having some solder-related problems with displays of all types. This was because they were learning how to implement the new lead-free solder standards/materials properly. Flat panels of such a vintage were particularly susceptible. I was thinking your TV was about the "right" age where this could rear its ugly head, but I really don't know, just a thought... That bulb could suck a fair bit of juice I'd imagine, so a flakey connection (solder or connector) could get quite hot to the point it has a high resistance (bulb goes out), cools and connection gets re-made for a while.
