Component i/p

[enfield250]

I have just connected my Lite-on Lvw5004 to the Q321, via the rgb cable connections using a Belkin av20001 cable the picture keeps flashing on and off, then I get a message on the screen saying "Unsupported". Am I doing something wrong, the DVR is set to component o/p. Any ideas I don't think it's the cable as the colours are fine when ith picture is on. :(

[Coops]

Can your provide full belkin part number of the cable you are using. That part number is incomplete.

Coops,
The Cable is Belkin AV21000ea06. This should work without a problem.

[Coops]

OK

So you have the Component connections made via the CR CB and Y Component connections to the appropriate connections on the component in feed on the q321. Double check you have not crossed a feed.

Also Do you have any other video feed connected to your Liteon unit or Just the component.

How long does it stay on between flashes?

Did you try both component feed on Q321?

[enfield250]

I've tried both component feeds on the Q321, the cables have been checked and are correctly connected, I have tried with the scart connections in and out on the Lite-on. The picture flashes up for no more than 5 seconds but, not every 5 secs. It will flash up for 5 secs and then nothing for about 30 secs then flash up again for 5 secs. after a couple of mins. it then displays unsupported, then it will start flashing again. when the picture is on the colour is correct, but, it is oversize and flickers.

[Coops]

So it does the same thing with Scart as well???

Do you have another device you can try on TV such as cable or sky box. VCR or Standard DVD player.

Do these items also cause flicker or is it only with Liteon Drive

Can I just butt in here as well. I also had this problem on both component inputs with an Ellion dvr515a.
I then tried it with an old Daewoo dvg6000d dvd player and everything was fine on both inputs, so either the Ellion was incompatible or faulty.
Either way I have had a refund on it claiming it to be faulty.
Unfortunately I didn't have anything else with component connections on to try other permutations but I'm wondering now if this set is incompatible with some dvd recorders via component input, and if it is, how do we find out which. I'm currently looking for a new dvd recorder and just hope everything will be okay. No problems with scart sockets though.

No scart is ok! however the LVW5004 does not have RGB scart output, and the picture it decidedly better via component, I also have a Foretec Star Ultra+ box connected to the full scart, because that does have RGB scart output and it improves the quality no end. I have upgraded the firmware on the Lite-on and it ran perfectly for 20mins, before it stopped. It looks like a gain problem, as when the picture is flashing on and off it is over size. The info display on the Q321, shows "Comp2 576i" when it is running ok and "no signal" when it is not. Is there a service menu on the Q321 where setting can be changed.
Cheers,

[Coops]

There should be no reason to alter any setting that i can think of. What kind of setting are you looking for???

576I would seem right. As my Sony DVD transmits on Component at 576I or 576P depending on if i use Interlace or Progressive.

At the moment i am not sure what to suggest. There is something obviously wrong somewhere as long as your drive is transmitting signal via component connection and your have the cables correctly wired from the player to the TV i cannot see why this should not work.

So either the Liteon Drive has a fault on its component feed or the TV has an issue on its component feeds as i believe you said you already checked the cables.

Do you have other Video output feeds connected to your liteon player such as composite or scart as well as the components?

What options does drive have for component video output??

I cannot think of any options on the q321 that could be changed. When i connected my system to Q321 i just plugged it all in turned everything on and everything worked straight away no problem.

I think I may have found the problem, apparently the LVW5004 only sends sync pulses on the green when in component mode. Is the Q321 happy with this or does it look for sync pulses from another source.

[Coops]

Well no this should be ok, socket Y ( The green coloured one although it does not actually send a green picture ) which is the "luma" component and controls the brightness of the image is also used in all setups that use YCbCr connections as the sync feed.

Cb ( Blue Socket ) is blue minus Luma ( Y-B ) and Cr is red minus Luma ( Y-R)

Now YCbCr is a digital signal. There is another type of component feed which is YPbPr. This is the same sort of thing but it is analog. And then there is also RGB which does mean proper Red, Green and Blue Signals. This orginal form of video RGB is where the term sync on green comes from. Even though todays standard component video does not actually use red, green and blue signal they still use the green connector as sync.

Anyway moving on.......... the Q321 being a digital TV uses the YCbCr setup for component feeds and checking over your spec sheet for your product LVW-5004 it would appear that this unit outputs in YCbCr as well. You can check this by looking at the little sockets on the back and see what letters it has to each one. So technically there should be no problem here.

As long as cables are connected in correct order on back of drive and they are connected in the correct order on TV and all on the same component connection group either component 1 YCbCr +LR Audio or Component 2 YCbCr + LR audio and as stated in your LVW-5004 manual you have selected component out as your video feed i can see no reason why this should not work.

Also make sure that if you are using professional Components cables they are connected the right way around. Some of the higher quality cables only work in one direction. I know mine do at home and they have an arrow on the plugs to show what way the signal travels on the cable. This is to reduce signal loss and improve signal quality.

Apart from that i am not sure what else it could be.

[enfield250]

Thanks, Coops. I'll try the cables the other way round.
Cheers.

[enfield250]

Well Coops,
I have tried the cables the other way round, still no joy. The problem is definately with the Lite-on as I have connected another DVD player to the component i/p and it works perfectly. Lite-on support suggest connecting through and AV modulator, I would have thought that this converted the signal to RF, which will give a poorer picture. As an aside are we sure that the Q321 has only 1 scart socket with a RGB input. As the lite-on unit is RGB bypass, when I connect via the Lite-on, in bypass I get an excellent picture which downgrades when I turn the unit on, and it is connected to the H-Scart input.

[Coops]

Ok well at least we know which device is now the problem if you tried other drive and that works.

As far as i know q321 Has One Full scart and One Half Scart.

Question

My Sony HDD Recorder, you can change the type of interface the scart ports are using. For example i can set them to either be RGB or Composite or s-video.
So if my output scart is set to composite but unit is in off Bypass mode it shows RGB, when i turn it on it changes output to composite. Downgrade picture. I obviously have both my scart set to RGB mode so no matter if its on or off it stays in RGB. Do you have some setting like that in yours??

That might explain the degradation when you switch unit on and thus stop bypass mode which is working in RGB.

I am afraid to say i can no longer help with why liteon won't connect via component. There is obviously something wrong but i cannot think of anything else to try with regard to that.
