I see several US-only models in the list, so those wouldn't be dual voltage.

Here, off the top of my head, would be the best guesses at the part causing the risk:

Degaussing thermistor (gets bad connections and keeps cycling on/off, causing AC line voltage to burn a hole in the board)



Flyback (most likely cause in my opinion... Arcs, smokes & flames, but usually blows the fuse before starting any fire)

HVR block (can arc and flame out like a blow torch, but seldom seen in Sonys. More likely in RCA CTC-169 projection version, etc)

AC line input choke (can arc and cause AC line voltage to burn holes in the board)

With that said, ANY, and I mean ANY item which plugs in, or has batteries, can cause a fire. So can Coke bottles, fancy crystal decorations in the sun, etc etc etc.

If everyone used common sense, there would be little to worry about. If you leave your 1984 Sony TV, or any appliance running unattended in an empty house, you probably are asking for a problem sooner or later.
