Hi

Did a detailed search but could locate an answer - although some were getting close. So here goes.

I am attempting to use the MySky component loop through functionalility. I have what I assume are the right connectors (SCART-RGB from Jaycar). I also have the MySky set to component out.

When I press the "AV" or "OFF" buttons on the MySky remote, I get what appears to be a degraded PQ that also loses it's horizontal stability (ie the picture zigs in some places and zags in others - very technical I know).

I also assume that the connectors are OK (they are new).

Is there something that I am missing? Is the VCR SCART on MySky supposed to pass through component? What do you think the issue is?

Thanks

CA

I have got this going, but, from memory, I needed the "right scart" there is a scart in and a scart out plug, There is an adapter you can get that is scart to rgb with an in/out switch on it, I used this to get it working then swapped out cables to make work.

Yeah, that's what I thought.

I know SCART is bi-directional but I guess the RCA plugs that connect the DVD output to the SCART VCR socket on MySky have to be connected to the component ins in the SCART plug to work (not the outs)?

I assumed that if I get any picture then the plugs are wired the right way around - if there is no picture then they aren't. Is that a fair assumption? If I get an (admittedly bad), picture where would it be coming from if it wasn't component?

I also have the s-video of the DVD connected through my receiver to the RPTV - could this be an issue? Could this be the dodgy picture I am seeing on loop-through?

I would rather not go get a different cable on the off chance it will work.

Cheers

It could be the svideo, if the picture is black and white, (at least that is what is did for me)

It could also depend on whether the svideo input is shared with one of the composite inputs, i.e one or the other but not both.

It sounds like you are trying to feed the scart cable the wrong way round, I have seen scart cables that have two sets of rca plugs, an in and an out it might be worth seeing if you can find one of those.

No - it's in colour - just bad.

I'll try taking all the non-component video feeds out of the dvd player and see if the picture is still there. If ity goes then I obviously have the wrong cable - although Jaycar didn't specify any others.

I saw the 6 plug versions - but thought it would be a waste.

Maybe ....maybe not ....

The specs in the Jaycar catalogue state the 6 plug versions are A/V connectors - which suggests that at least 2 of these are audio. Hmm....

The jaycar part that does the scart to rca +svideo and is switchable is PA3659

This is what I used to get it sorted.

As far I am aware the pass through of component does work. The 6 RCA-SCART adaptor is for composite in and out, and audio in and out. Audio and composite has independant in and out on SCART, this is how a VCR is normally operated by one SCART. The RGB circuits (via which Component is also conveyed R=Cr, B=Cb, G=Y) are bi directional.

Sounds like you have a composite/audio in/out cable.

The Jaycar cable you require is WQ7255, ie a standard RGB or Component SCART<>RCA, the audio might not work though as this cable is wired as audio out, and is what would be normally used on the TV SCART to feed you TV.

The cables I have are both WQ7245.

Will these not work?

There didn't seem to be "in" and "out" versions so I assumed they would all be the same.

Are you saying that I would need a "SCART to component out" cable for the MySky "SCART TV" to TV connection and a "component in to SCART" cable for the DVD to MySky Scart Video connection?

Man this is confusing to explain.

Thanks

The WQ7245 should work, as this just picks up the RGB channels. Have you ensured that you have connected each of the three to the correct RCA sockets on the DVD.

I presume the MySky to TV works correctly in component, the only issue is the VCR SCART loop through of component video, it was my understanding that this does work.

Well it does sort of work - but with the picture waving all over the show intermitently.

The DVD works fine connected directly to the TV component in terminals and the MySky works fine using it's SCART TV socket connected to the TV's component in terminals. I have even switched the WQ7245's around and it still does it - so that would eliminate a problem with either cable.

Got me beat.

Your not trying to feed upscaled or progressive component thru the mysky are you? I think progressive uses different sync levels, i know the timing is different (has to be)

No - although my DVD player is outputs progressive (NTSC only) that is switched off. Exactly the same output that the TV presents very nicely direct from the DVD player, is messed up intermitently when looped through MySky.

Any chance that my MySky is faulty?

Only other thing is that the mysky's green input doesn't like sync signals on it, since that will never happen in RGB mode they dont need to support it.

Hmm.. Not sure what that means.

Are you suggesting I stop the STB determining the aspect ratio of the picture?
