Horisontal colored bars on CLD-D925

[Guest]

Archived from groups: alt.video.laserdisc (More info?)

Hi there.

My Pioneer CLD-2950 had a rather soft videooutput and I was recommended to
get my hands on a Pioneer CLD-D925 instead. Yesterday it arrived.

The picture from the CLD-D925 is indeed sharper, but.....

When playing NTSC-discs, the videooutput is filled with these horisontal
yellow/pink bars.
I've done the usual Google-diggin' and it seems that a lot of folks have had
this problem with the CLD-D925 before me.
They swapped the "infected" players with new ones from Pioneer.
Perhaps Pioneer discovered the flaw early and modified something, so the
later production of the CLD-D925 didn't have this problem.

Now, that's around 7-8 years ago and I'm a bit stucked with this machine.

These are the symptoms:

1: Almost all NTSC-discs [CAV and CLV] have these horisontal yellow/pink
lines, whenever there's red, orange or skincolor.
2: Also on blue color, there's these bars....but they're not yellow/pink,
but just darker than blue.
3: The problem is not there, when playing PAL discs.
4: The bars are most visible at the beginning of the played side and fades
away as the outer end is reached.
5: They can also be seen, when using the still-picture.

Honestly. It looks like the image produced from a very worn-out VHS machine.

I've have used these Laserdiscs for testing.

PAL, Queen "Greatest Flix" CLV, CAV. [OK]
PAL, Terminator 2, CLV. [OK]
PAL, Star Wars, Return of the Jedi, CLV. [OK]
NTSC, Terminator 1, CLV. [OK]

NTSC, Back to the future II, CLV, [Not OK. Bars]
NTSC, RoboCop, Criterion, CAV, [Not OK. Bars]
NTSC, The Abyss, CLV, [Not OK. Bars]
NTSC, Disney, The Lion King, CLV, [Not OK. Bars]
NTSC, Titanic, CLV, [Not OK. Bars]

What's this problem about ?
Can I do something myself ?
Can I do something with the NTSC potentiometers on the printlayout ?
Have someone had their CLD-D925 in for repair and know what can be done ?

I thank everyone in advance.

Best regards.

I have pretty much the same problem on my CLD-95.

Thanks for the reply Miles.
It's very useful.

I didn't expect a high-end player to have this fault/symptom.
My CLD-2950 plays everything without bars'n stribes and that's odd.

Something's wrong. Who knows what to do ?
Years ago people have their faulty players swapped with new ones, that
didn't have this symptom.
Where's the difference between a CLD-D925 and a CLD-D925 ? ;-)

Your CLD-95 is a fine looking machine.
It breaks my technological heart to see such a beautiful machine having this
defect too.

I consider this forum to have the very best Laser-brains around
Someone knows what's wrong. Please.

Thanks in advance.

Best regards

I just found out, that the bars and stribes almost dissappears, when you
switch the [HQ-Circuit] to ON.

Okay...the picture looses a bit detail, but the overall impression is
better.

Strange.

What is the HQ circuit?

Miles.

The HQ-Curcuit should, to my understanding, cut off the higest frequency in
the RF-signal stored on the LD.
It gives a softer picture, but also takes away the finest details in the
picture.

Why it's called a HQ-Curcuit ?
HQ equals High Quality.
Well....I suppose Pioneer thought that the average consumer would appreciate
the soft picture, without crisp detail and with lower picture noise.
Actually the best picture is achieved when HQ is set to OFF.

Still I don't know exactly what's wrong, when the majority of my NTSC-discs
reveals these "bars" of demolished colors, when showing red, orange or
skincolor.
I'd kinda hope, that Kurtis had some knowledge here.
Strange.

By the way.
I've done some further diggin'
There's a lot of potmeters inside of the machine.
I tried to "tweak" a bit.
The Videolevel potentiometer if turned up, gave a bloomed picture. Turned
all the way down [counterclockwise] gave me a better picture on my TV. [B&O
LX4500]
I'm getting my hands on the servicemanual for the Pioneer CLD-D925 in a
couple of days.
Perhaps this will reveal some goodies.

Best regards.

Hi Brian,

Please let me/us know what you find out in tweaking a 925.
Although I still find the 925 a very respectable player (better then my
CLD704) I think it can be tweaked to do even better.
Luckily for me I don't have the colored bars problem you have.. Is it on the
scart output or is it a problem with the s-vhs output? or both?

I will
Don't hold your breath though. I'm not in posession of an oscilloscope yet.
Therefore my tweaks rely on information I can get from others.
That's why I would like to give the Guru Himself, Mr. Kurtis Bahr, a couple
of hundreds of cyber-sixpacks for revealing some of his much-wanted
knowledge ;-)

I really think that too. I still wonder why there isn't any site, where all
the tricks are listed.

It's on the S-Video output.
The information provided by the Internet [Googlesearching] said, that the
composite output is taken *after* the S-Video has been created from the
signal of the LD.
I've got to do some more testing here.

"I'll be back"

Best regards
Brian

You probably already tried that but don't you have to 'say' to your tv-set
that your are feeding s-vhs to-it (presuming that you are using a scart
connector to a scart-socket with s-vhs capabilities)?

when I feed s-vhs to my tv using a scart in I have to 'configure' that scart
in my tv-setup to 's-vhs in'.

I'm using the B&O LX4500 only as a monitor.
The videofeed goes from the S-Video-out on the Pioneer CLD-D925 to the
dedicated S-Video-in on the B&O LX4500.
No Scart here Pure S-video cabling.

I haven't experienced any problems with my Pioneer CLD-2950, which is my
daughters property now.
This unit plays well without any problems like the CLD-D925.
On the other hand. The picture delivered from the CLD-2950 is very soft and
I'm a crispy-image fan ;-)

The servicemanuals for both machines, should arrive within a week.

Best regards
Brian.
