Hi,

I POSTED THIS IN THE HOME THEATRE SECTION BUT NOW I REALISE IT SHOULD HAVE GONE HERE

I've been trying to get Sky connected through to the tv in the bedroom. I want decent picture, so I splashed out and bought this from Jaycar.
http://www.jaycar.co.nz/productView.asp?ID=AR1875
I have also bought this, to split the HDMI signal:
http://www.jaycar.co.nz/productView.asp?ID=AC1620

However the signal to both tvs comes and goes. The three red lights on the Splitter go off and on rather randomly. Does this suggest that the problem is 'handshaking'?

This is the set-up in the lounge:
Sky box > HDMI Splitter Box (into 'Input', via HDMI cable)
HDMI Splitter Box > HDMI Sender (into 'Output 1' via HDMI cable)
HDMI Splitter Box > Sony Home Theatre box (into 'Output 2' via HDMI cable)
Sony Home Theatre box > Samsung 40 inch LCD TV (via HDMI cable)

I use a Harmony remote to power on the Sony Home Theatre and TV in order to watch tv. I keep the Sky HDMI box on all the time. I've been leaving the HMDI splitter on all the time.

In the bedoom:
HDMI Receiver > LG 26 inch tv (via HDMI cable)

Have been trying for 5 days but I just can't get this to work consistently. Sometimes it all seems to be working, but turning something off and then on again will screw it all up. Last night I thought I'd nailed it when I changed the order that the Harmony remote turns things on in the lounge, and HDMI cabled everything with all the power off, and then turned power on from the source (Sky box) all the way through the process. The Sky feed into the bedroom was completely stable until I gave up on the cricket about 11pm. I turned everything off in the bedroom (so the Sky box and splitter box and HMDI Sender in lounge was left on). However this morning the kids woke me up complaining at 6am that the lounge tv wouldn't turn on. They'd pushed 'Watch TV' on the Harmony remote, which turns on the Sony Home Theatre and TV, but that didn't trigger the light on the HDMI splitter to provide a feed. So the screen was blank.

Does anyone know what this might be, or what I should try?
At the point my plan is to give up on splitting the HDMI signal (and try to get a refund from Jaycar for the splitter) and perhaps get a Component to HDMI cable and hook the Component end to the back of the Sky Box and the HDMI end into the HDMI Sender. I assume that would work? However I'm reluctant to give up just yet, I get the feeling I'm missing something simple?
I have tested the HMD cables on other things and they all seem to work (they're all new, from PB Tech). One thing I did read somewhere (Rapallo's FAQ I believe) was that HMDI cables should be at least 2m long - could that be the issue (mine are 1.5m long)?

Any help would be greatly appreciated!

Cheers,
Craig.

I'm not sure about the products you have, but we bought one of: http://www.jaycar.co.nz/productView.asp?ID=AC1695&keywords=hdmi+splitter&form=KEYWORD to split an HDMI signal from a Bluray player to 3 TVs and it works perfectly.

Is it possible for you to test by bringing the TV from the bedroom out to the lounge and eliminating the wireless sender?

I don't trust HDMI over wireless.

Thanks trig42, good idea about testing it without the wireless hdmi sender. I will try that.

The most frustrating thing is that sometimes it does work (as I say, last night I had Sky streaming in the bedroom perfectly, and I was turning the tv and home theatre off and on in the lounge and the Sky in the bedroom held up fine).

I guess that's why people have jobs going around sorting this stuff out. If all else fails, I'll probably 'get a man in'.....arrrrggggh.

I've seen some splitters with option to lock the display detection to a fixed setting instead of detecting the TVs that are connected. It might be that say the wireless is dropping out very briefly, causing the local TV to be detected, and when the wireless comes back up it detects the remote TV again.

Agree, don't trust wireless for anything real time. And my job involves designing products with wireless capabilities. We had issues with our Sky reception, after a few days of issues it turned out to be the cordless phone we've used for years while having sky, just caused a resonance when it was moved a couple of cm.

Oh man, that's depressing to hear it could even be something like that (I can see me wasting many many more hours and not being able to get the right result).

Two things I will try tonight:
1. trig42's suggestion to see if the wireless part of the equation is the problem
2. I just read somewhere that if a second tv doesn't do 1080p, then that can create issues unless you change the Sky setting so it sends out a lower quality signal....does that sound legit? The LG tv in the bedoom is only 720p. Might have play around with that and see it makes any difference.

I'd say it is the wireless aspect which is causing the issues.

Is there no way you could run an HDMI cable from the splitter to the second TV?

Hi - thanks tukapa1...
Nah, will require quite a bit of effort to get an hdmi cable to the second tv.
Anyway, I took the wireless aspect out of the equation last night. Still had issues. So I went to Jaycar this morning and swapped the splitter for another one. Either that one was faulty, or I have something else going on that's screwing things up. Assuming it wasn't faulty, my current thinking is that perhaps the Sony Home Theatre is the problem. I noticed last night that 'HDMI' is flashing on and off on the display when it's clearly trying to get a picture. This makes me think it's a 'handshaking' issue. As originally mentioned, I'm splitting straight out of the MySkyHDI box. The HDMI connection to my main tv goes via my Sony Home Theatre. I might try splitting after it comes out of that. Who knows, worth a go.
When you add up the variables, there are just so many variations (which connects to what, what order things are turned on, etc).
