Audio Video Signal Interference

higster

Hi, I've a (rather expensive) Philips AV sender hooked up to sky+ box sending to bedroom upstairs. However, I'm getting some kind of interference. I've switched off wireless internet, microwave, mobile phones & home DECT phone and still have it. I've hooked the reciever to a tv next door to where the sky box is and still there. Anything I'm missing that might cause the interference?

Thanks.

What kind of interference?
Has it always been there or has it only started recently? i.e. has something been introduced recently that might be conflicting with the sender?
Have you tried the different "channels" available on the unit?
Most units have several channels available to try and avoid this very issue.
Usually selectable on both the sender and the receiver i.e. channel 1,2,3,4 or a,b,c,d?

Sound crackling (badly) & lines going across screen.

Has been there since moved into house about 9 months ago.

Yep, has 4 & tried them all but with little/no difference (bar channel 4 knocked out my wireless broadband)

Have you eliminated the likes of:

Fluorescent lighting.

Central Heating pump/motor

Fridge compressor


Is the interference there all of the time, non stop? or is it intermittent?

Fluorescent lighting.
None in the house

Central Heating pump/motor
tried it with heating off, no joy

Fridge compressor
Hmmm, didn't try that...

All the time

Plasma screens and LCD screens can cause interference on remote senders so I'm guessing this might be the case with the AV sending part too.

Also CFL bulbs can cause problems I'm told, but I think you've already discounted this.

Perhaps the fault lies within the video sender. If it's inside the guarantee period, take it back.

I recently bought wireless headphones from Maplin. I spent a couple of hours trying to get them to work without interference, switching everything off and on that could have been the cause.

I then bought some relatively cheap Lidl ones and they worked straight out of the box, no messing.

Probably a different signal set-up to AV senders but it shows that any fault isn't always where you expect it to be.
