SOURCE: so weird help me out please
One of the PCB's in the back is failing.
Unfortunately there are about 13 different PCB's in the back, it will be difficult to ascertain which it is without the back removed.
The TV would need to be on aswell, so safety is an obvious issue.
Some quite high voltages exist inside the TV, you do NOT want to be touching some parts when it is on, there are no labels to tell you what is live and what is not either.
Unless you are competent with electronics then I would take it to a repair shop.
If you are, then open it up, and listen to tell which PCB is making the noise.
I take no responsibility in your safety, that's up to you.
Should be easy enough to figure it out though.
I hope this helps.
