Our lad inherited out old first-gen LCD HDTV (11 years old). Been fine (lost remote apart) for him for 5 years ...Now it still works, but when you turn it on, there's a crackling/fizzing sound from the _centre_ of the back. It's definitely not coming from the speakers.The second I first heard it I thought "capacitor" ?It's a very light sound - not sharp enough to be arcing. And whatever it is doesn't seem to affect the TV operation. Just be a nuisance.If I could be bothered to pop round and spend a few minutes investigating, where would the wisdom of uk.d-i-y suggest I look ?He's already bought a replacement, so this has been relegated to "games console" :)

Crackly fizzy (mechanical ?) noise from TV ?

Is there any "burned plastic" smell? That would really raise the alarm. Tracking across something non flammable like glass or ceramic is not necessarily so serious. That will still generate an "ozone" smell, if there is enough current

And at least it's not like the bad old days when colour TVs first came in. My brother in law (*very* experienced) was a TV repair man at the time, and lost a co-worker to electrocution.

Some statistics from 2009

"FLATSCREEN televisions are the cause of an increasing number of house fires, Queensland Fire and Rescue Service figures reveal.

Televisions were found to have ignited almost 70 house fires in the past five years, with more than half of those causing extensive damage.

But other appliances, including heaters and clothes dryers, contributed to a much larger proportion of the 5251 fires started by electrical equipment in the period."
