Hi All

Have a DVL-919 (the ‘E’ model) that is suffering from picture breakup. It’s a second-hand player so I don’t have any history on it other than being a 1998 manufacturing date.

It’s most noticeable during FBI warnings, studio logos, opening credits. That sort of thing. Basically anything with text becomes an unreadable shimmer. And the general picture quality is pretty iffy.

Don’t think it’s a 'rot' problem as have tried several discs but it still could be, I guess.

It tends to be a lot worse towards the start of discs on both sides. Playing a disc upside down—using side B of the player to play side A—exhibits much the same issue.

Audio is typically reproduced without issues on both the analog and digital tracks. It’s just the video that’s suffering.

Have tried running the composite output through two different composite to HDMI converters with the same result. Also tried a composite to HDMI capture card with a few different settings.

Any thoughts on where to start on this one? Have I just simply got a setting wrong? Is this a rookie error of some sort? Or is it time to break out the service manual and adjust centering and tracking?

See screen captures below.

Many thanks for any thoughts!

Hi, I had the same issue when I replaced the laser pickup on my CLD D925, all the texts at the beginning were not clear, basically, to me it looks like it's the same issue, the tracking might be off and the player needs some calibration.
As I don't have any test discs nor oscilloscope for measurement, I tried and "eyeballed" the thing, it's not perfect but it works for me.
Also, did you just get the player and it always played like this, or did it worked "normally" before, and this is a new issue ?

Wait a minute, just noticed something

Have you tried not using any upscaler or converter and put the composite input directly into your screen ?

Since you aren't using LD as LD was intended, i.e. running your player into your TV of the era.

This is not rot, lucky you didn't start posting that this is rot.

Do what they said above and try running straight into a TV, you won't get this issue.

And also turn down your sharpness.

That looks pretty messy. Looks digital to me, maybe the TV is trying to do some processing on it? I have the same player and have hooked it up directly to modern TVs but haven't seen anything similar. How does it look on non-text parts of the disc?

I couldn't see the images, but looking at the code I could see the image URLs. For anyone else who can't see them try clicking these :

Oh how I hate this statement. If you really want "as it was intended" then use nothing but an RF cable to connect the player!

The whole history of LD is one of embracing and bringing on new technology to get the best PQ you could. During the 90's players became chock-full of various digital processing technologies to improve their performance. IIRC Pioneer kept manufacturing players until 2009 so "of the era" includes plasma and also LCD.

Now admittedly lots of LCD's/flat panels are really s**t at handling a composite signal (more recent ones especially OLED's seem to be getting better on that). But in my house a pretty typical LCD projector and to a lesser degree LCD screen give a better overall picture than the Sony CRT of the 90's era that was the "family TV" of the time.

Of course in this case bypassing any separate convertor/scaler etc being used is a sensible step to rule out that being the issue.

While I know where you are coming from audioboyz, my post was fast.

I'm meaning when you connect your LD player to your computer to try and capture, these can do it but really weren't meant to do that.
And with all the tweeking you need to do to get the LD play right through a computer.

Scalers and other devices are fine, I haven't used a CRT in over 7 years on my LDs and can't go back after knowing how to tweek.

I only yesterday discovered a setting on my TV that eliminates a good deal of video noise. It does seem to give the image a bit of a green tint, but I can adjust that with the R/G slider.

I really wish my TV would just let me save settings so I could easily switch between specific ones depending on the source!

And don't get me wrong; CRT's are great for LD, but not necessarily going to automatically give you the best result. Admittedly that statement's a bit of a button-pusher for me because usually it's some numpty trying to tell us a CRT is "the only way to do it right". (You're no numpty rein-o!)

:lol: Numpty

From the pictures he posted it sure looks like its running through a computer, I sort of remember those types of glitches when getting bad PCBs on
arcade boards or when the connector wasn't making a clean contact.

You can get a great image from any set as long as its setup right, but computers are a whole nother ball of wax.

Thanks for your feedback, everyone. I appreciate it.

The player is newish to me.

I have two different composite-to-HDMI boxes with the same result using both.

Yes, I had been connecting to a PC via an HDMI box rather than a TV screen but will try this.

Some other LDs seem better without as much breakup during logos/titles. I noticed that when the logos/titles start to fade out, they look perfect. It’s as if I’m getting too much video signal into the HDMI box.

This is mostly observed during the first 5 minutes or so of playback however does seem to manifest to a lesser degree throughout.

I tried DVDs and it works perfectly—no picture or sound issues at all.

Certainly, in the ideal world there would be synergy between the player and screen—I would be using a CRT. But that’s not feasible for me right now.

So, if I’m not doing any of this in the spirit of how we should be watching an LD, I do apologize!

I see, well, you should definitely try without using your hdmi converter, it's probably the cause.

It's the laser pickup. You need to replace it.

Lets not jump to repairs Tech Kaflo when he has it connected a wrong way or the computer is not picking up the analog signal.

Yeh please don't do any tweeks or "repairs" till you have fed it directly to your TV & not through anything else - that could fix the issue.

Hope it is a simple fix & a direct feed helps, please keep us posted.

Cheers
