I have a TV I'm trying to fix. I do know a bit about electronics, but not a lot The power supply is making a weird buzzing sort of sound and will eventually shut off until it cools down. The TV works great otherwise.
It sounds like the buzzing is coming from the bridge rectifier. While I was probing around, I did get a bit of a shock from heat sink that the rectifier is on. It meters out ok though which is confusing to me lol
I tested the output voltages and my 24v is all over the place.
I will post a link to a small video of the sound, right click and save as
