I'm using these widgets to push HDMI from a central media closet to a TV in the living room:

hdmi over cat5 with ir

They work fairly well, however, whenever the oven is on, and each time it 'clicks' (i.e. turns on a heating element, I assume), I lose the HDMI signal for a few seconds. The oven will click on and off every minute or 2, so it's very annoying. To a lesser extent it occurs when the A/C comes on, or nearby light switches are pressed.

Obviously, there's some kind of interference being generated from the electrical circuits that's disrupting the HDMI signal over the twin Cat5e cables. it's a new house, but I didn't see it before the sheet rock went up, so I do not know if any of the cat5 cables comes close to the electrical cabling, although there's no way the TV cat5 can get close to the cooker electrical feed, unless the electrician or AV company took a very odd cable route.

So, my question - is my problem due to over-sensitive cat5/HDMI extenders, or, is there some kind of magical suppressor I can fit to the electrical circuit to limit the interference?

I should probably add that the HDMI signal is going thru an Onkyo SR607, which I believe has issues of it's own, but I don't think it's related to this particular problem, although I stand to be corrected! most the time it's just passing thru the signal, the Onkyo is not actually turned on.

Thanks, Pete

I too have the same issue.... different cat6 extender but exactly the same symptoms and the same AVamp...

However my issue started a little differently...

Turn on amp lcd and source ...... perfect picture...... 10 minutes tiny red pixels apearing on the darkest areas of the image ....... 10 minutes more Lots of red pixels in dark areas and green pixels in the brioghtest areas .... 10 minutes more and the image is mainly red and green with a smattering of porper colour ...... 10 minutes more complete loss of sync.

A friend is an electrician who walked in the house stuck is tester in a socket and anounced an earth leak....... 3 hours later traced back to the main consumer board ( which was installed in 1979 ) £200 later a new consumer unit and the picture is perfect....

Untill....... one of the fridge compressors's kicks in... and a blip in sync and back to perfect picture.... another 20 minutes and loss of sync untill I interveine with ether a back to standy by and on again with the screen or flick the onkyo to a different input and back to the original source.... I have 2 freezers and two fridges ( left over from bachelor days of a beer fridge in the garage ) and it seems that dependent on which units compressor kicks in determines how bad the sync loss is.. and its very age dependent... the biggest oldest fridge causes complete loss, whilst the 4 year old model causes a blip.......


Any Ideas out there ?

I've never had any issues with the picture quality, just the loss of sync. It's a new house, with new appliances (that's not to say there's no wiring issues), so it only seems to be the cooker that causes the issue. And lightening storms.

My fix is the same as yours. Using a Harmony 1 remote, I turn on the TV, then the Onkyo Amp, switch it to a different input, switch it back to the TiVo input, then power it off. 9 times out of 10 that means that by the time the TV (a Sharp 52" panel) is ready to show a picture, the amp is done with it's little dance, and things are all good. Unless one of the family forgets to keep the remote pointed at the right place, then things get ugly.

Every now and then, the amp-dance doesn't fix it, so then I pull one of the cat5 plugs (I presume the one that's carrying the power for the extender, since the lights on the box go out), plug it back in and everything is good again.

I plan on switching out the Amp soon, as it runs crazy hot (even when it's in standby), and isn't helping the situation, but I don't think that'll resolve the core issue.
