I wanted to start a new thread as the old one has kind of run it's course and my question will get lost inside it.

Would a Scart to Component cable help with my Humax line problem? And would it improve the picture generally speaking? Such as this one:

http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=260205834932

I am guessing not as the Source is still the same. I know the problem isn't specifically a Scart one as I've gone through all the options.

Here are pictures showing the problem I have displaying my Humax 9200 PVR to my Samsung LCD TV via Fully wired scart cable:

You will also see jaggies at the bottom of the ladies face in the second picture and jaggies all over the third one. These are a result of the lines.

There is a 5 page thread here detailing everything I've tried:

RIGHT

never mind all that

what tv have you got

what devices have you got dvd etc

how are they wired up INCLUDING route of RF aerial cable from aerial all the way to telly

Hi.

I have seen a few threads devoted to this topic, but i have not had this problem myself with my 9200t.

I have a Panasonic HD Vreal2 TV, and it up-scales and processes the picture from the PVR, maybe that`s why i have not seen this problem.

regards

John.

yes having read the mismatch of info unless you tell us exact model of dvd-recorder as there are a few choices we cant help you

and is it a tb humax or tbx

all boring i know but all can help

software update 14 jan 2008

have you got it ?

1.00.21

signal strength?

Why would that matter?

I had some picture degradation (lines running at an angle slightly off vertical) after upgrading to the latest firmware (21) and doing a system reset.
I then recalled that I had previously had to shift the 9200T UHF output from ch 36 (to ch 26) to avoid some crosstalk with the analogue C5 broadcast on ch 35.

Doing that fixed the problem.

The symptoms similar to yours do not necessarily come from the same cause but it may be worth checking.

A Samsung LE32R41BX 32" HD Ready LCD TV. It's a 2005 model.


Pioneer DV-868AVi DVD Player connected by HDMI
Pioneer DVR-540HX HDD/DVD Recorder connected by Component.
The Humax is a direct feed to the TV by RGB Scart.


RF lead from wall
Then to Humax PVR
Then to HDD/DVD Recorder

The TV is Analogue only and has no RF lead plugged into it.


HUMAX PVR9200T/S with .21 firmware.


Strength 60%
Quality 100%

It never changes.


Thanks.

I don't have the analogue cable plugged into my TV so don't think that's it but have changed it to RF 60 just in case.


The DVD Recorder is fed directly to the TV by Component it's not connected to the Humax PVR. Why do you ask?

Thanks for kindly taking the time to help but I really just want the original question answered. I've been through so many options already in the original thread. Please free to offer any suggestions but I'm pretty/sure all the obvious ones have been tested.

What has managed to help is adding a 230 ohm resistor to one end of the Scart cable. This hasn't eliminated it entirely but has reduced the problem.

Martin Liddle kindly did this for me.

where exactly did you add the resistor? I presume it was between 2 pins.

I'd guess so but I don't really know sorry as I didn't fit it. Martin Liddle (whose a member on this forum) fitted it for me.

No it was inserted into the circuit connected at pin 20 at the TV end.

So you were just attenuating the incoming video signal?.

Yes. I was following the suggestion here Hummy.org.uk thread on picture flicker, see post 29 particularly. I am very open to more appropriate suggestion for things to try.

I suffer from the same thing, was told it was the quality, or lack of, the signal where i live, I have an rgb to comp (as no scart inputs on my krell pro/amp), makes no difference.

What TV do you have? It seems to be a particular problem with some Samsung's.

I don't believe it's signal related. What is your signal strength/quality?


Thanks. I suspected that would be the case

The lack or quality of broadcast signal should make zero difference to the picture quality available from a local source (STB/PVR/DVD) connected at signal (RGB/Component/S/CVBS) level.

I recently read of someone who reduced a similar effect by allowing the analogue (and digital?) tuner(s) on their TV to scan and store, even though there was no RF connection to the TV and all channel positions became set to RF69.

I suspect that an RGB to component converter would go some way to resolving the problem, as that (like connecting via the DVD recorder) would break the direct connection of the Humax CV/sync signal to the TV.

I've just done that on my Samsung TV and as it didn't find any signal it didn't update any of the channels RF numbers. I guess I could do it manually but all except for the 5 Analogue channels are on 69 anyway.

What the user described just isn't possible when no channel is getting a signal period. It could've been something else.


Really? I thought Component was able to accept a standard RGB signal so will just be showing a similar image that the Scart outputs.

Over on the AV Forums thread I started someone has a Scart to Component cable on order:

http://www.avforums.com/forums/showt...=666824&page=3

I've received a replacement Scart to S-Video cable and AGAIN they've sent me the complelely wrong cable and not what I bought. I've now been sent twice one of these:

I've asked for a refund as I don't believe they have the decent versions with the crucial switch direction switch. I should've received one of these:

http://i16.ebayimg.com/06/i/000/bb/61/511c_1.JPG

That said: It did occur to me I can actually test S-Video. I happen to have one of these:

http://img513.imageshack.us/img513/5386/107879fw3.jpg

Which has a direction switch so I used it in conjection with a basic S-Video lead and was able to get a colour picture.

Sadly the picture was so full of dot crawl around all objects (like Edge Enhancement on DVDs) it was definitely way worse than the RGB picture even with the problem I have. The dot crawl was also moving making it very obvious.

The line issue did go away though, not that I'm surprised about this when it's an RGB issue. Now I'm not sure if this dot crawl would be resolved by a decent S-Video cable, but regardless the colours weren't anywhere near as vibrant as RGB so I suspect S-Video would still look worse.

I know this because in the EPG with S-Video there is no dot crawl so you can see a good idea of what S-Video would look like.

It's a projector, not a tv, every other soure is fine, even tried dvd via rgb to comp box rather than dvi, no lines, signal strength is 40-73%, quality norm 100.

What does this means sorry?

To confirm the lines look the same as my line problem? If so it sounds like your projector (what make?) handles RGB in a similar way to my Samsung LCD. Personally I think the Humax 9200 doesn't send out a standard RGB signal that some TVs/Projectors have a problem with.

I think it's going to be hard to 100% eliminate.

Theres been talk in your other thread of upscaling by the TV's. I think this is your problem as you have eliminated the Humax by connecting to various other tV's.

I have 2 Samsung LCD TV's 19" & 23, on each I have turned down the sharpness setting to soften the picture slightly.

This elimintated most of my problems, and the images are still great.

Worth a try - apologies if you have already tried this.

Glenn.

Thanks. It's not as if I can stop that one , it could be.


I have tried this, even setting the sharpness to zero but it made no difference. Thanks anyway.
