Home Theater Glitch Resolved

[405x5]

At first, I thought I might be looking at a impending failure of a board component within the XMC, as the display would glitch intermittently, now and then. 

However when I realized EVERYTHING plugged into my existing SURGE PROTECTOR was glitching.... I was relieved. 

I've never experienced an actual failure of a surge protector, but I now understand, more clearly than ever, that these throw away devices  NEED to get tossed after not too long a period of time....perhaps 3 to 5 years?
My new one was a little over 30 bucks, so that's around 8 or nine dollars a year for surge protection.....not bad.

While at it, I took a closer look at the chain of how everything was getting powered and cleaned house a bit......all is well. 
It's possible my Central Air problems did the thing in....but it doesn't matter any more and I'm back in business.

Is your surge protector a UPS? Some of those output a square wave which isn't terribly great for electronic components.

Yes and know. Check out BRICK WALL brand , No need to toss 'em

Interesting....can you provide additional data on the wave....haven't heard that one.
The faulty surge protector was a Monster 6 outlet intended for home theater electronics.
Worked fine for a few years at least then something went south (MOV) I suppose.
Replaced with a Belkin 12 outlet and all is good.

I don't know much but this type of UPS outputs a square wave. While devices are built for sine waves.

Ok I see where that's going.
I personally would not want any type of battery backup associated with my home theater gear.

There's another type of surge protection I also steer clear of and that's the type that will cut power to plugged in devices when the MOV protection fails. That COULD shut components down while the high power amps. Plugged directly into the circuit are still running.

Why? Fear is based in what electrical fact? Only emotion justified that conclusion - that wild speculation.

Output from a UPS is potentially problematic for motorized appliances. And perfectly idea for electronics. Otherwise fear also says what part is harmed. Honesty cites a datasheet spec number.

What happens when a cleanest 120 volt sine wave or the 'dirtiest' square wave is incoming? Electronics routinely filter it, convert it to DC, filter it again, and then convert it to well over 300 volts radio frequency spikes. Does not matter if cleanest sine wave or dirtiest square wave. Electronics remain at risk from the same well over 300 volt radio wave spikes.

And not a problem. Because superior filters, galvanic isolation, and regulation convert 'dirtiest' possible spikes into rock stable, low DC voltages that do not vary by even 0.2 volts. Do not vary even when AC voltage drops so much that incandescent bulbs dim to 40% intensity.

Stop looking for magic boxes. What is superior is already inside electronics.

Spikes and other tiny anomalies that create Monster failures are routinely make irrelevant by what is already inside all electronics. Did you first read specification numbers? No numbers defines the many who have no knowledge; and plenty of emotion.

Effective protection, that costs about $1 per protected appliance, means a protector remains functional for decades after multiple direct lightning strikes. Please learn from over 100 years of well proven science and experience. Ignore so many myths - especially any without spec numbers.

Foolish is a myth that a protector does protection by disconnecting. Again, where are the numbers. Anyone who says that is irresponsible. For example, a potentially destructive transient does its damage and terminated in microseconds. Anything that would disconnect takes millisecond, seconds or minutes. Conclusions change 180 degrees as soon as numbers are learned.

Or how does that millimeters 'disconnect' gap stop what three miles of sky cannot? At what point do numbers expose myths and lies?

Learn more numbers. Why would anyone assume central air causes any appliance damage? If it did, a first thing damaged is a closest item. That central air would destroy itself. Where is this air conditioner that creates 600 volt transients? Then you are replacing dimmer switches, clocks, dishwasher, refrigerator, and GFCIs every hour. Please learn that the many who invent mythical threats and emotional fears have no idea what the numbers are. Or what is really a threat. They only know what fiction and lies (also called advertising) have told them to fear. Ignore them.

Which ones should be ignored? Everyone that does not include numerous spec numbers with each recommendation. No numbers is a first indication of the naive or a scammer.

Holy smokes!
I feel like my bride 👰 just got mad and chased me down the hallway with a broomstick.
Err uuhhh.....all I said.... was....I don't want battery back up in the loop with my HT gear. Period.
Home theater gear is just a toy. If the power goes out, oh well, I'll watch and listen some other time.

Battery backup for work....SURE I'll take it👌.
I did enjoy your rant however.....can I please have some of whatever that is you were smokin😴😊😂😍.
Just kidding!

I have a very nice Belkin UPS system that I use for my desk computer and assorted computer gear. I tried it out with my music/HT gear once when I was auditioning power sources and it was the worst of everything I tried. Battery backup UPS systems are great for computers but don't belong in music and HT gear.

That UPS myth was exposed for the benefit of others who foolishly made a UPS recommendation without first learning facts. UPS is a near zero protection device with 'dirty' electricity (as richguy learned) that is not harmful to electronics. Nothing was emotional. Why insert emotions into what is only a technical reply?

Also discussed is what everyone should be considering. It is your best recommendation. It was never mentioned and probably unknown by others.

Your power strip protector did nothing useful. And could have made home theater damage easier.

That technical discussion introduced something that must exist to protect what is already robust protection inside every home theater appliance. Why is a 'dirtiest' UPS not harmful? Because best protection is already inside those electronics. That existing and robust protection is why 'dirtiest' power from a UPS is not harmful.

BTW, 'dirty' power from a UPS could have also damaged that near zero, plug-in protector. And also less robust appliances such as a refrigerator, vacuum cleaner, or garage door opener. Another example of what is and is not effective.

Your concern is an anomaly that might overwhelm existing and superior protection. How often is the threat? Maybe once every seven year depending on conditions in your venue - such as geology.
