They can't be that unsafe! TV's used the same technology for a lot longer and I repaired hundreds of them without the hint of any danger. The workshop I started in didn't have isolation transformers and the benches were fitted with two-pin plugs so worked on the sets (radio's and TV's) on raw mains. All I did was check the chassis with a neon screwdriver to see if it was live or not.
An isolation transformer doesn't really make the sets safer. You can still get a nasty belt if you touch anything live. All the transformer does is enable you to connect earthed test equipment.
