It could be High voltage discharge, this causes an ozone smell, this
can occur from any high voltage point (20kv 30kv) especially if a
connection has a sharp point or termination wire spike. If the back
has vents, look through them in a darkened room and see if an arc is
visible. Also underneath vents if possible.

What could possibly be wrong? What could be causing the TV to smell
like this?

Thanks.
