Question about Philips Magnavox DVD/VCR Dual Player

VCR playback issues

The VCR component of my machine will only play back tapes that it recorded itself. it's the weirdest damn thing. I can record programs and watch them perfectly fine, but if I put in a commercial pre-recorded tape, it plays the picture for about 2 seconds, then stops itself. it has similar trouble when I pop in a tape that was recorded by a different VCR.

it's not a connection problem, because DVD, television channels and tapes that *will* play come out just fine. and obvioulsy it's not even that the VCR doesn't work at all, so we're just stumped about why it's selectively rejecting tapes.

    thank you! I'm going to repost because a VCR with that problem might have a different cause than a DVD player (er, just by logic...I don't know much about electronics)

    leethedeuce, it doesn't actually eject the tape. instead, the video cuts out and leaves me with that blue screen. the tape stays in the vcr.

Hi there.

It's deffinately missalignment of the tape head.

Was it dropped at all - or moved?

Worldvet has a solution, but a simpler method may be to GENTLY pull on the read spool assembly.
In theory, the problem was cause by inertia causing the tape head to drop, this may be aleviated by moving the reader up.
The question is - by how much? Trial and error running the thing on the bench with a pre recorded tape untill you get a good signal.
Please be careful when working with live equipment. If in any doubt, use an experienced technician.

Ok this is actually a comon problem. The heads are not alighned right. Which will make recording and play back not a problem but other videotapes won't play because the tracks are off in regards to the heads.
If you are patient you can adjust the heads yourself but otherwise a video shop can have that done in 5 minutes.

Hello,

This is a common issue with VCRs. Your situation is not unusual and has to do with the tracking. Most VCRs won't allow you to manually adjust tracking anymore and rely on automatic tracking. Unfortunately this means your VCR has to read the very bottom of the tape correctly to get the tracking data information. When the alignment path on your machine is off as much as it is, you will have this issue.

This can be resolved by adjusting the tape path height inside the VCR. But, do not attempt to adjust the tracking head height while in playback, you will damage the head as it is hunting for the tracking data path. You have to make each adjustment and then insert the tape from another source and notice the changes. What you do is move the tracking path head downward incrementally so you can read your tapes and tapes from another source. You can find the tape path schematic for your model by using Google.

Hope this gets you headed in the right direction but I'm not certain you will be happy with the results.

Regards,
Worldvet

Hard to say without seeing it but it may be the LED under the prism in the middle of the circuit board, it is a common problem on philips VCRs. After it ejects the tape does it try to pull the carriage back down?

    Yes most likely you will need to have the heads and led aligned. As this will most likely cost you around what new unit is. I would just replace it. You can pick dual dvd/vcr decks for fairly cheap. If you need anything else let me know.

I had a similar issue with a DVD player, in that it wouldn't play any commercial or rental DVD's, but it would play them if I burned a copy on my laptop. Turned out to be board inside the machine. I had to replace it.

How a VCR and Videotape Work and the Most Common Problems


A common complaint about videotape is that over time, playback becomes unstable and often deteriorates to the point that the tape becomes unplayable or that the tape works on one VCR, but not another. All of these problems can be traced to tape path alignment in the VCR and damage to the tape itself. I will address each issue separately.
First you need to understand a little about the tape media. When you record on VHS videotape, the recorder lays down three (four for stereo sound) magnetic tracks on the ½ inch wide tape. Analog audio is recorded along the top edge as a thin horizontal stripe (or parallel stripes for stereo) for the entire length of the recording. In the center of the tape, video is recorded as diagonal parallel stripes by two or four heads that rotate on a drum at 360 RPM. On the bottom edge (the most vulnerable place for damage to occur) there is another horizontal track that is critical to playback. It is the sync track and it's purpose is provide the VCR with the feedback it requires to maintain the tape speed within extremely tight parameters. If the tape does not move at a precise speed, the picture and sound can become unstable to the point that it will be unusable.
As you record, a fixed frequency sine wave is recorded on the sync track. If during recording, the tape speed increases or decreases, it will be reflected on the sync track. During playback, the VCR's circuitry senses the small millisecond-to-millisecond speed fluctuations of the tape movement over the heads and adjusts the speed so the tape speed always matches the speed at which it was recorded. If the sync track is ever damaged, your tape can become useless.
Unfortunately, videotape is a very delicate media. It is easily damaged and once damaged, it usually cannot be repaired. The most common failure is due to tape stretch. Videotape is not very elastic. Anything more then slight tension during use can stretch the tape to the point that it cannot rebound. If the sync track is stretched, the recorded frequency will change and the VCR will react accordingly by making incorrect speed corrections resulting in picture and sound disruptions. Your recorder has tensioning arms that control tape tension as it moves through the system. If the tension in the tape path is incorrectly adjusted, the tape will be damaged as it is recorded or played.
Improper storage is the other common cause of edge damage. If you lay your cassettes flat for prolonged periods, the weight of the tape above will press against the sync track and can damage it. Always store your tapes vertically. Extremes in temperature and humidity can cause stretch. Store tapes in a cool dry place. Also, periodically restack your tapes. To restack a tape, put it in your recorder and fast-forward it to the end and back to the beginning. That will redistribute the tension on the tape. After playing a tape, always restack it once or twice. I have a large collection; over 1,000 tapes. I cannot restack them all on a regular basis. But when I play them, I take that as an opportunity to restack them.
Now that you understand some basics about the media, I will now turn you attention to your VCR. As I hope you are starting to understand, proper playback requires precise alignment of many moving elements. The two broad categories are tape path alignment and head alignment. None of this is a do it yourself job. In addition to specialized electronic test equipment, VCR alignment requires specialized tools along with expensive custom made for the brand and model alignment jigs along with (again expensive) alignment tapes. The alignment tape is important beyond the obvious. In order for a tape recorded on one machine to play properly on another, the two machines must have matching alignment. VCR manufacturers record their own alignment tapes using precisely and frequently aligned recorders. The tapes are used to align a specified number of VCRs and then discarded because each time a tape is used it wares. Since there is a uniform standard for these tapes, a tape recorded on one brand of VCR should play on another. That is the theory.
Now for the real world; the consistent interchangeability we all wish for is hard to maintain. Consider this. The tolerances that must be maintained at every point in all of the processes relative to VCRs and tapes are very close to what is possible; little room for slight variations. Since the tolerance for one part of the process may accumulate with another part of the process either mathematically positively or negatively, it is often the case that each individual part of the chain is within tolerance, but the sum total is out of tolerance.
What in plane language does this all mean? Two alignment tapes made on the same machine will be different. Tapes from different manufactures will be different. The tape you local technician or factory service center uses will have inconsistencies. The net effect is that two seemingly properly aligned machines may not be able to properly play each other's tapes.
I do not mean to suggest that you should not have your VCR properly aligned and maintained by a professional. My point is that videotape is an old technology with flaws that could not fully be overcome in the time frame that it would have been profitable for manufacturers to do so. That is why we have moved on to digital technologies. My advice is to enjoy your videotapes while you can. They will not last forever. If you have important tapes, transfer them to digital media to protect your memories as soon as possible.

Panasonic HVX200 will not play back tape


Your playback heads might be clogged. I am not sure if this camera with give you a RF warning if your record heads get clogged. Also most professional machines drums are rated at 1000 - 1500 hours before they need to be replaced. If you are at 500 and never cleaned the heads it is time to. Run a cleaning tape a few times.

Too fast playback of video cassette


Hi,

Initially, I am inclined to think that nothing is wrong. It is just most likely that that particular tape was recorded in a different speed other than what your VCR is capable of playing. This is a form of compression wherein a longer recording/playing time is squeezed into the same type/kind of tape. The various settings are SP, LP, EP or even an XP. Pls click here to give you an idea of the recording time/speed at different settings.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

VCR tape playback not good


Check your "tracking" If the tape played fine in the old machine, then tracking is the answer, provided that the new machine records good.

VCR Play Back is OK, but Recording produces Blue Screen on playback


If the heads are TOO dirty, a head cleaner will not help. If you are cinfident enough to open up the recorder, then they can be cleaned manually.

Disconnect the VCR from the mains.

Remove the screews from the side and back (if applicable) of the lid.

Remove the lid.

Look at the large drum (set at a slight angle) If you gently rotate the drum you will see 2 or 4 small sensors set into the drum.

Tear of a clean piece of A4 paper about 1inch square.

Hold between thumb and first finger and rub the centre of the paper against each sensor in turn. Make sure the edge of the paper does not catch the sensor.

After each sensor check the paper for dirt (black marks) and change paper if need be.

Try a recording / playback.

Repeat if necessary.

VCR recording


As with all tape related recording equiptment, the path the tape follows in your machine will collect debris which will interfere with the synchronizing playback signals originally recorded on our tape when first recorded. The "ROLLING" is the loss of those synchronizing signals and the "skewing" of the tape where the heads are now reading between the recorded information causing noise at the top or bottom or throughout the entire screen. SOLUTION for about 85% of machines exhibiting this problem is CLEANING and inspection of tape path alignment best done with a calibrated playback tape for accuracy. HOPE this helps . . . Jaszy

VCR won't tape and get no playback


First check how good / bad are your recordings. Take a current / recent recording done after this problem cropped up, and play it back on another VCR - maybe a friend's. If the recording plays back badly- showing the symptoms you described, then the problem is still dirty or worn out Video Heads. If the Recording plays back perfectly on the friend's machine, but plays back badly on your machine, I still suggest that you try cleaning the Heads one more time, and if the problem is not resolved, it is time to trash the VCR. One last question, you say that you have reset the channels. Are the reception channels' images clear? I may be able to give some more suggestions, based on this response.
