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?

    Hi, I'm having this same horizontal rolling problem. When I tried using the remote to fix it, I couldn't tell where to arrow down or across because I can't read the screen while it's rolling. Could you detail the steps so I can do it blind?

    I am having the same problem and cannot figure this out blindly. I think I have tried everything. Any other suggestions?

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.

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.

Yeah I have a Sylvania model # SP A2751 106. It is a old **** tube tv. When I go to hook up the the dvd player and switch it to vcr/aux the picture rolls in bars upwards. Its not the dvd player tried it on...

There should be a preset resistor on circuit board of old CRT based TVs, designated as vertical rolling adjust. Try to locate it and adjust a little till rolling stops, while playing the DVD. The set will be live during this process, so be careful. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact any experienced service technician, or the nearest service center.

VHS Video Tape - Picture Roll.

Picture roll is caused by the frame rate being out of sync with the play back device. If the tape was recorded at say 25 f/m and is being played back at 26f/m. If you can, adjust the frame rate until the picture stands still.

Picture roll, loss of vertical sync.

I opened the cover, found nothing smoked or loose, no tweaks available, in short there was nothing I could do without diagnostic gear. All other sources in my system were fine, so simple substitution confirmed the problem was output of Teac dvd player. Taking it to a repair shop would be $50 up front for fix-or-not... So, I went to Walmart and replaced it with a Sony DVD player for about $40. Regret loosing the look of matching components with my Teac receiver, cassette player but it's job is to play movies. Fixtya!

if the problem is in the VCR, it can be adjusted. if you don't know how to do it, then yu should bring it a repair shop.
if it in the DVD, then the cost can be high. (replacement of the DVD reader)

Rolling picture

Not likely. They probably just need to be cleaned and re-alligned. Rates vary, but our shop charges $20 to do that.
