No - it's fact, and patently absurd to suggest otherwise.

Circuit components transfer much of their heat through matter to
regions of lower temperature - conduction. This means they are not
efficient sources of heat (for heating your environment). You could
perhaps snuggle up to the chassis of your amplifier to maximize the
potential.

Also consider airflow. Take lightbulbs for example. Are they located
in floors or ceilings? Heat rises, by the way.

Whatever!

Still, the fact remains that virtually all the current passing through most
electrical equipment is directly or indirectly dissipated as heat.

So the TV's power supply does get "a bit warm", you accept that? Well if the
room (ambient temperature) is cooler than the circuitry then thermodynamics
require that that heat will transfer to the cooler surroundings increasing
their temperature.

There is a principal in thermodynamics that states that eventually all the
energy in the universe will have "decayed" into heat. There will be no more
energy potential left any where. It's called the "Heat Death". It's going to
take a long while something like 10^10^23 years.
