Why is my mains voltage fluctuating?
It may be the capacitors in the power supply charging and discharging, which would suggest that the mains voltage is fluctuating.
What does "not turned on" mean?
Does not turned on mean powered down with the remote or switched off/unplugged from the wall.
What extension to use to stop noise?
Make sure you get a surge AND RFI extension like the one I linked to for the best chance of stopping the noise.
Does a fridge make a noise when it's not running?
As far as I can tell the noises do indeed start when the fridge kicks in. I have noticed the noise when the fridge is not running but it is nowhere near as bad.
The Internal Parts Contract and Click
The TV Has A Power Supply Problem
- Clicking noises in your TV may be the consequence of a power supply issue. A TV’s power supply works to change the alternating current (AC) to the direct current (DC) the TV uses. The internal components of the power supply might cause a clicking sound when they activate. Power supplies use relay switches and a capacitor to change the current from ...
The TV Capacitor Is Faulty
- A faulty TV capacitor is another possible cause of clicking. The capacitor stores electricity before moving it through the rest of the circuit. TVs usually have a few capacitors in them, helping to keep the flow of power consistent. However, a broken capacitor can slow down the flow of power. The relays may not activate correctly when this happens, leading to a loud sound. The TV may al…
There Are Hardware Issues
- Popping and clicking noises can indicate various hardware issues. When none of the above clicking issues seem to be causing the problem, you’ll want to send the TV back for repairs. If it still has a warranty, this would be the best course of action for you to take. For those familiar with TVs and electrical circuits, you can always open the TV and have a look for yourself. However, n…
Final Thoughts
- The internal parts of your TV likely make a clicking noise when they cool down and contract. If that’s the case, the TV is working fine and doesn’t need any repairs. Yet, there are other possible causes of noiseyou’ll want to fix. Sometimes, issues with the power supply or the capacitor can cause a TV to make popping or clicking sounds. It’s possible to repair the TV yourself or take it t…
