Yep if its got dead batteries its more trouble than your current situation, the batteries are there to let it sail through trouble, if they are dead it will sink with the input.

It's starting to sound like it's a bigger problem than I hoped.

Next year we're looking at getting some work done - I'll budget for an electrician then.

I'll treat my monitors blanking as 2 2 second break :)

A long extension cord to supply power to monitors fed from a different circuit?

CokemonZ:
When one of my appliances kicks in my monitors flick on and off. I'm thinking the conditioning aspect of the ups would deal with that. Would that work?

If you can find one, and if you can afford it, a ferroresonant power conditioner would probably do what you want.

Hi GZ'rs again.

Now that I work from home I'm starting to see some issues with the wiring in my house.

It seems 50% of my house is wired up via one cable run, Laundry, 1/2 my kitchen and my office.

What happens is that several times a day my monitors will blank, as something turns on - dishwasher, washing machine or dryer I expect.

It's not a disaster, but it's very annoying.

Everything that has capacitors in them - phone charger, surface dock, even my soundbar is fine - It only happens to the monitors. To be fair they are older, and I brought them second hand however they work perfectly - other than this.

I don't want to spend a lot of money fixing this, so I was thinking - If I get a secondhand line interactive UPS (and not care about the battery) would this solve the problem?

UPS keeps the voltage steady, monitors stop blanking....or would I need one with batteries in good condition?

Was looking at this as an example: https://www.trademe.co.nz/computers/peripherals/ups/listing-2275523130.htm?rsqid=770806f66a7747cc89952777a60767bf-016

Edit: made link work

I have this one: https://www.pbtech.co.nz/product/UPSDNX1200/Dynamix-UPSD1200-Defender-1200VA-720W-Line-Interac

You can have for $50, works fine still.

That link mentions it has "- Buck and boost AVR for voltage stabilization"

That sounds like me - where are you based? I am on the north shore in auckland, regularily between birkenhead and albany.

Even cheapies (and super, super old) of these look to go for a couple of hundred on trademe.

I'll keep my eyes open. Thanks for the idea.

I have an OEM Sola 1500 which you can borrow if you like to see if it fixes things. Weighs 40-50kg though, and depends on how close to Orkland you are in terms of moving it.

I plugged my Dell monitor into the second-hand UPS I got for $20 in today before we turned the clothes drier on. It's a Dynamix UPS1000, a really old model. My monitor doesn't flicker when the drier changes direction any more. The UPS makes a low volume high pitched noise when the drier is changing direction, I guess the monitor doesn't need much power supplied.

Good to know.

I found a guy selling two of those APC power conditioners for $20 on Facebook. Might give one of them a go.
