I have my computer connected to my TV via HDMI. Every time something electrical happens (fridge turns on, stove sparks, etc), the image on the TV goes black for a second and then comes back on. And before anyone asks, trust me, I checked other options, it is perfectly in sync with the fridge/stove/etc and not some random coincidence
Anyone have any ideas as to what is causing this or how I fix it? Or should I just get a new HDMI cable?
The lights do not flicker or dim when this happens.
Also, if it is on the same circuit, how do I figure that out?
And will connecting the TV to a regular surge protector work, or do I need to put it on a voltage stabilizer?
Best Answer
When the fridge turns on (some) and when (some) ovens start their capacitors pull a ton of current to start the motor/function needed.
If these are on the same circuit as your TV this is a pretty big issue and the fluctuations could cause damage to your TV circuit board over time.
Even if these aren't on the same circuit your TV is getting a voltage fluctuation from the main circuit. Your TV having intelligence built in probably has its own way of handling these fluctuations - with one turning off some extraneous functions... like HDMI working.
HDMI cables work or don't. If yours is showing a picture then getting a "better" one won't help.
What I would do? First make sure that your TV is not on the same circuit as the fridge and stove. In some places this wouldn't meet code and it certainly isn't good for the electronics.
If they are not on the same circuit then you may need to call the electric company and figure out if they have anything that is causing fluctuations on your line when something high voltage is plugged in. They may fix the issue or offer suggestions - and a lot of times this is free. If the electric company believes it is an issue on your side you will need to troubleshoot why you have this interference - usually a loose connection in the main box.
And lastly you may need to change appliances or tv... Not saying you have to do this but you gave a specific example. Your TV may not handle any kind of voltage fluctuation well. Whenever a major appliance turns on there will often be a little voltage fluctuation. Most electronics are built to handle this. Maybe your TV does not handle this well and your electricity issue is not really a big deal. Or maybe your TV handles this normally and this would happen with all/most TVs.
Question too - do your light flicker or dim during this initially engagement?
