Philips Time Lapse Vcr RT24A5T

This refurbished vcr has less than 2000 hours recording but was manufactured in August 1999. I purchased it a few months ago online and It was working perfectly up until a few days ago. It will now record on 8 hour speed for approximately twenty minutes. Then it shuts down and ejects the tape. When recording on 8 hour recording speed, the take up reel of the cassette is moving erratically and almost comes to a stop. On 3 hour recording speed, the take up reel moves smoothly. Error message is 4934. Have tried different tapes, new and old, with same result. Any help appreciated.

    I have now realized that the 4934 code on the display is a refererence to a built in service test programme. Pressing the "OK" button produces a display screen on my monitor. This display reads as follows:
    ERROR: NO PULSES R. REEL
    ERR STAT: RECORD
    INIT SWITCH: O
    THREADING TACO: 0
    Tape end sensor: 1
    TAPE BEGIN SENSOR: 1
    RECORD PROTECTION: 0
    REEL TACHO L:0 R:1

    TAPE DECK STATUS: 0A
    OCOT4-5N ODPU-3U
    OTDPC-3N

    As previously mentioned, the tape up reel movement is erratic. The tape backs up on the take up reel and then tightens up. This process repeats itself until the cassette finally ejects. This happens during both record and playback. Any Philips time lapse vcr repair people out there? Thanks.

    Also, the display on the vcr is now reading:
    GR D03 C 15

    Please disregard previous comment about take up reel moving smoothly on 3 hour recording speed. Tke up reel moves erratically on all speeds.Tape action is almost stop and go with the result that the tape bunches up and the cassette is ejected. Thanks.

    This vcr has very few hours on it. Could this be a clutch or pressure roller problem? Any service people out there who actually worked on commercial Philips time lapse vcr's? Thanks. Note: I have three more of these units that are functioning properly and I could always swap parts for testing. Thanks.

    The take up reel moves erratically at all speeds which causes the tape to back up and the vcr will eject the tape.

    Thanks for the suggestions. The unit in question is clearly marked model number RT24A5T as is marked on the back of the unit and also in the service manual. One suggestion was that the drive motor was starting to wear out. Is the drive motor also called the capstan motor? There is also a threading motor on this unit. I will try to determine if these parts are the same as in my Philips TL24A5T which I rarely use. Thanks

    Hi and good day,

    This vcr has very few hours but the machines was built in 1999. Maybe the rubber has dried out. I have it recording now with the bottom panel off. The belt is running smootly but the take up reel is definetly not moving smoothly and I expect the tape cassette to be ejected in twenty minutes or so.. I will try the belt from the Philips TL24A5T unit. Thanks.

  • Carol Richards
    Carol Richards Aug 10, 2009

    Tried a new belt and the problem remains. Take up reel is moving erratically until finally the cassette ejects.

    Hi,

    I have cleaned the idler rubber tire on a few occassions. I tried changing the drive belt but it seems to have made matters worse. Now the take up reel does not move and the tape cassette unwinds in the machine and then ejects. This machine has three motors. I have switched the threading motor with one from another machine that works properly. This did not help. Pressing the cl/code button brings up ascreen with the following information:

    ERROR: THREADING ERROR.

    ERR STAT: 2h

    INIT SWITCH: 0

    THREADING TACHO: 0

    TAPE END SENSOR: 1

    TAPE BEGIN SENSOR: 1

    RECORD PROTECTION: 0

    REEL TACHO L:0 R:1

    TAPE DECK STATUS: 09

    OCOT4-5N ODPU-3U OTDPC-3N



    On the good machine:

    REEL TACHO L:0 R:0



    Maybe the problem has something to do with the reel tacho readings. Thanks. I will submit photos later.

    Hi and good day,

    Thanks for the information. I recently purchased the service manual for this unit. Is there any way that I can send you this document by email? I have looked for a plastic wheel with a tire that drives the take-up reel but can only find a plastic gear with teeth. The manual includes a parts list. If you can identify the part for me then I can remove one from my TL 24A5T unit as a test. Thanks

  • Carol Richards
    Carol Richards Aug 15, 2009

    Hi and good day,

    I sent along the document as requested. Were you able to receive it? If not I can try again. Thanks and have a nice day.

Hi Welcome to Fixya,
I have repaired many VCRs and still have my Philip time lapse VCR, most VCR issues are from moving parts that require maintainance after so many hours. Cleaning the surfaces (rubber,other) will help the vcr operate smoother. . but the two main problems are with the mode switch needing to be cleaned, it is connected to the main gear and tells the VCRs computer what postion gears are in, taking it apart to clean it is very tricky and the switch has to be put back in the correct timing spot. So either attempt a good cleaning with some alchohol or take the VCR in to get it checked at a reputable shop.
Thks

The idler wheel has become a little slippery. This is a plastic wheel with a rubber tire. The rubber has dried up a bit and no longer has enough grip to keep the tape tight on the takeup side. The unit has safety sensors built in to detect whether or not the takeup side is moving and will eject the tape when no movement is detected. This is done to prevent the tape from accumulating inside the unit. This is a simple repair for any shop that works on VCRs. A good cleaning and replacement of the rubber components should restore this to factory fresh. The issue is related to the heat generated inside the unit and the over all elapsed time not the actual usage hours. You should expect this type of maintnance to be required every 5-8 years of age.

The parts cost for this should not exceed $20.

    I have just seen all of your previous responses which were not available to me prior to my initial posting. These units all work essentially the same and the takeup side will generate the indications you posted. There are sensors under each reel that are checked for movement. I noticed that you cleaned the idler tire a number of times. That rarely works. If you can, replace either the tire or the entire idler. If you have other units that work and the idler replacement does not resolve the problem, please update this and I'll research this further. There are other timing related issues with the gears under the chassis that can cause this if they are off by one tooth.



    Keep me posted.



    Thanks,

    Dan

  • ABRsvcs Aug 12, 2009

    If you have the service manual, please send it to: dansabrservicesATyahooDOTcom. I will check it and update this.



    The problem is not likely to be the capstan motor directly. That is the motor that runs the main tape transport drive. If you locate the pinch roller, the capstan motor runs the shaft that the pinch roller pushes against with the tape in between the shaft and the pinch roller. It is possible that the idler is gear driven rather than with a rubber tire. In that case, the idler may not be in the correct position. This can be a combination of the drive belt below the chassis, the felt washer inside the idler assembly, and the lubricant at the idler pivot point.



    Shoot along the service manual and I'll update this with some things to check and do.



    Thanks,

    Dan

Please check Idler that drives take up reel in playback mode, if Idler has rubber Tyre, please clean it with alcohol.
Take reel should run smoothly in playback / recording mode on what ever speed is selected.
If it is possible, post a picture of VCR mechanism for easy understanding.
Thanks.

Sound like the motor drive is going out, On slow speed recording 8 hours causing the motor drive speed to be faulty. On high speed motor tend to work lot smoother. replacing motor drive should solve the problems. being 1999 I couldn't tell you if parts available as the motor drive it self. I believe yo have to buy the whole cassette drive assembly and pretty costly. Your local electronic repair shop will be able to tell you if parts available and the cost to fix it.

Unfortunately there is not much you can do for this particular problem because the drive motor is becoming weak, the drive motor must be replaced, this is less difficult than one would think however locating and purchasing a drive motor is not so easy, you may find one on ebay

Good luck

My vcr will not recognise the year 2010 it goes back to 1990 so I can no longer use the timer to record when I am not there.


All depending on when your unit was manufactured, it might not support the year 2010. You will have to upgrade to a new VCR or DVD player to use the timer record function. Good luck to you!

The tape drive mechanism is defective. Most likely a jam in the roller track. It will cost more to repair than the unit is worth. 99% of all Time Lapse VCR's have been switched out with digital recorders. You can get a basic DVR for about 1000.

Greetings dexter11,

It appears that there is a gap in the recent technologies. It appears most of the VCR/DVD-R combo's you can purchase will not allow you to "timer record". There are a few from a few manufactures that do allow this but they are the more expensive units with integrated digital tuners.

Now I know you said you were not interested in TIVO because of the lack of a home phone line, but if you have an internet connection it will allow you to use your wireless network to receive programing updates as well.

Happy Recording.
