Power conditioner needed????

I'll vote for a cable induced issue. Most troublesome audio and frequently video anomolies are the result of the cable or satellite grounding.

Simply go out to the power pole where the cable or sat is grounded and lift (disconnect) it temporarily. Wait about 30 mins and look at the picture. it may taek a few more mins but in an hour or so you should know if that is the issue.

it's a simple enough task/test. If it is the issue there are isolation transformers that can solve the problem very cheaply.

True too you might not have a good enough ground. Sandy soil sheds water quickly too. Arid areas can be issues. I've heard from more than one source simply watering the ground rod area can remedy things.... which might account for the late night no prob thingy you have going on there.

If in an apt. simply remove the coax feeding the sat/cable box. Wait a while like i SAID ABOVE AND CHECK IT OUT.

Battery chargers too can cause problems in an audio or video rig if in close ckt proximity to the gear. timers too, like on hot water heaters, dishwashers, and or lighting.

If it is a ground loop, a power filter/conditioner usually isn't the fix.

you can also try using a decent sized ext cord and plug the TV into another ckt altogether.

Dew point raises at night, and your situation eases then, and why I say I feel it is a ground oriented issue. Unless you and your neighbor are using the same service I doubt the neighbor is the problem.

Good luck

I don't know about the radio transmitter thingy... it would have to be real close given the FCC regs on output transmission power but not everyone plays by the rules in that arena.... it'll be easy to find out... simply look for the tower/antenna. it should be pretty big/tall.

Back in the 40s, my folks were in Biloxi Mx. at Keesler AFB. They had an apt. off base. My mom would play the radio on her fav station. Now and then she heard some other conversation coming over the radio ch a bit garbled and in a different language.

She told someone on base about it as she worked for the PX, and my Dad was in hte USAF. it turned out someone else in that same apt bldg was transmitting info about the base to another location... so she inadvertently helped capture a spy by paying attention to her radio.

There's an answer for every electrical oriented issue. Most of the time it is found out for what it really is. sometimes it isn't.

usually it's one of three things... an opened ckt which equates to no power. A resistive connection which equates to an over draw of current to operate a thing, usually causing breeakers to trip routinely. or a ground somewhere on one leg or the other of a ckt.

A faulty wiring device can be any of or all of the above.

I think the ground loop issues, or seeming ground loop issues stem from the service itself. In some areas the neutral bus and ground bus at the service/meter are tied together.

Adaptive connectors which attempt to emmulate one they are not, like XLR>RCA, if not wired according to the way the maker of the item says, might well cause issues.

Reversing polarity along the way in a homes wiring can be problematic. Likewise, cables not terminated at either or both ends can be issues.

The fix often rests in going back to the last thing one has added or changed prior to the noticed descrepency.

Everything was fine until I plugged in the whosit to the whatzit.

...until I added cable.

.... got this new so & so... yada yada...

If it isn't obvious, like loose connections, burned receptacles, etc. just start at one end and go thru to the other. problems are normally at either end. Feed or supply. If not, ya just gotta check out the middle. visual inspections well reveal 90% of what the issue truly is.

DVI does not have as many conductors in it as HDMI does. The cable itself could be bad, or the source might not like being converted, Or the display/receiver might not dig it.

I use a DVI to HDMI adapter, and run HDMI CABLE instead of using a dual terminated cord.

it works great off the pc video card to the Onkyo rec. $5 from Dcables in TX.
