Howdy; Questions:
1) How does one check that the line voltage/amperage to an electrical outlet is a)constant, b)has correct values, & c)is "noise free".
2)how does one correct a)to c)if there is a problem?
3)is there a single device to correct all of the above?
This has arisen due to a comment by a tech doing a check on my Pioneer HD Monitor due to the presence of horizontal wide stripes/bars visible with all input modes & all devices (dvd/vcr/sat etc)

Doug-
You've got three separate things you need to consider with regard to the power going to your equipment.
1) Surge Protection
2) Powerline Noise
3) Voltage Stabilization

Most power conditioning companies divide their product lines into separate components for each one of these problems. Some combine two or all three into one high end device.

Check out this page [Link: monstercables.com] for a good idea on the different options available.

Steve; Thanks I will check it out BUT - how do I tell if I need it??

Doug,
The equipment used to record power line events can
be rented at: http://www.atecorp.com

Just get one of cheaper Dranetz units (you won't need
3 phase), hook it up, and start recording. However,
if you don't suspect a power problem, you probably
don't have one.

It's sounds like a ground loop from your cable! Disconnect your cable and see if the problem goes away
You should have a power line surge and conditioner like Panamax.

You usually dont see hum bars on all inputs, but ground loops can make alot of bad things happen in the video and audio.

Thanks for all the suggestions;
The Tech called Pioneer & they are shipping him 2 "boards"to replace in the set. The Tech & Pioneer did not think it a Power problem. It will take 3-4weeks (back ordered) to get the boards & for the Tech to install them. I'll wait & see till then.
