Picture rolling when I play DVDs

Unit is about 1 yr old and has always been great. Recently, we tried to play a DVD and the picture rolls rapidly from top to bottom. Everything else seems to be fully functional and the audio from the DVD is not distorted at all, just the picture. I have tried multiple A/V cables and have plugged in a different DVD player to the TV so I know the problem is in the unit somewhere. I wish there was an old-fashioned vertial hold knob on the back, but haven't found one yet. Any suggestions?

Re: Picture rolling when I play DVDs

Sorry about delay getting back to you. I think I have the steps here to do this fix blind. Hope it works out for you.

Power on your unit with no disk in it. Hit Setup once. Down arrow 3 times, then hit Demo/OK. Arrow right once, then arrow up once. Hit Demo/OK. Finally, hit Setup once to exit. That should get you back to NTSC and no more rolling. My unit still infrequently resets itself to PAL so you'll probably need to print this off and keep it handy.

Re: Picture rolling when I play DVDs

I used to have that same problem with my system. Fortunately for me, I still had the instruction booklets at the time so that helped me to figure it out. step 1: make sure there is no dvd in the dvd player before you start fixing the problem. Step 2: Press the "setup" button on the remote. Step 3: Once you have removed the dvd from the dvd player it should allow you to go to "preferences" in the setup menu. So do that. Step 4: Go to "TV TYPE" and make sure it's on NTSC. And then exit setup by pressing the setup button once again. And it should work. That's how it worked with my system at least. It seemed to switch the tv type by itself from NTSC to PAL which must be a flaw in the system. I thought I was the only one with that problem. Well, I hope that helped you at all. Have a good day.

This problem is with my home theater HT-TZ512. The disc sometimes loads, plays for 15-30 minutes, then randomly stops. The picture is still on screen. It looks like I pressed the pause button. When I...

You need to try a DVD Laser Lens Cleaning Disc.

If this doesn't work then you'll need to remove the cover and clean the Laser Lens with some Lens Cleaning Fluid and a QTip. Just use a few drops on the QTip and then wipe over again with a dry one.

If the above fails then its the Laser that's failing which isn't normally cost effective to replace.

A good way to check is if it will still play CDs but not DVDs then its the Laser.

Try using a laser lens cleaner DVD.
They run $1 to $10 depending on where you buy them, I have not seen a bad one (I usually pay $1 to $3 when I buy them for friends).
That should fix it.

Koss KS5190 Display mode stuck

I'm not ranked and I'm not a Guru, but I can solve this picture rolling when the problem is "the video was accidently changed from NTSC to PAL and you can't see what your doing to get it back". You will need the remote control unit. First, remove the disc from the tray. Now, turn the unit off with the power button. The tray will close by itself. After the display on the front of the unit goes out, turn the unit back on using the remote control. This will let you know the remote control unit is working. When the power comes back on and the display on the front of the DVD player says, "NO DISC", with the remote control and (very important) while pointing the remote at the player, (Remember to point the remote before pressing any buttons) press the "Down Arrow" button 3 times. This will take you to the "Display" box. Now, press the "Right Arrow" button 1 time. This will take you to the "TV Image"box. Now, press the "Down Arrow" 1 time, this will take you to the "PAL/NTSC" box. If you have done everything as I have tried to clearly lead you blindly to your destination. Press the "OK" button 1 time and the picture on the screen will stop rolling and change from black & white to color. You will have now changed your video output from PAL to NTSC. If you press "OK" again, it will start to roll again. If this did not take care of your problem, turn the player off and try it again.
The previous problem solvers were on the right track, but the track was rough and they just about derailed the train. Thanks to them, I had a track to follow. I had no other information, except what I found on "". MR. CD

Akai DHT300 screen rolling

The picture is rolling because there is no sync signal in the composite output. Are you using the RCA jack or the S-video output? Is there another small TV you could hook up for a test to see if the problem appears there? If it does, then the Akai has the issue and needs to be examined further. If not, the TV input may have an issue. You didn't say what the TV is but there is the possibility the video input is looking for external sync from the DVD but that's a bit of a stretch. Can you feed a different source into the video input of the TV to see if you get the same result? Hope this helps.
