Question about Philips DVP642 DVD Player

9 Answers

Philips DVP642/37 Plays breifly then ejects DVD and shuts off.

Our Philips DVP642/37 DVD player has worked great for some time. No video or audio issues. However it now will only play a brief portion of any DVD inserted into it. It doesn't seem to have any trouble loading (it may be just bit slower to load than usual). Then it plays the DVD intro like the copyright info and such and then quits playing and promptly ejects the DVD and shuts off.

Each time you try to load the DVD it plays for a shorter and shorter length of time until finally it immediately shuts down on each attempt.
I can't think it is the laser lens being dirty which we did clean with no effect. The picture quality and audio remain great until the unit just shuts off. When I had it apart, I did notice what seemed an unlikely amount of heat coming off what looks to be the power supply. I say it seemed unlikely just because it had only been on for a very brief time and it was already noticeably warmer there. That could be normal though.

Please tell me which is the component most likely to cause such an issue. Power supply going bad, over heating? Also since it is already past warranty and I have experience replacing computer parts, I would like to try my hand at fixing it myself so a recommendation as to where I might find the needed parts would be great too. Thanks
Vanessa

    Thank you for your response. We have a number of DVDs we play often like workout and kids movies. They are compatible with this DVD player, have always played before. Yes we have tried several of these DVDs, all known to work before, not working now. Your right about the heat sink. After posting my question I went back and looked at the PCB and say that the area that seemed warm did indeed look like a mini version of the heat sink in my PC. Yes we tried running the player with the player open with out any better outcome. So I guess over heating isn't the issue.

    It just seems strange that when it has been off for some time it runs for a bit longer before shutting down. But each succesive attempt results in shorter and shorter run times.

    Also, I should note that the front display continues to work fine. There are no clicking or grinding noises from the gears where the DVD sits when spinning or when the tray is opening and closing.

    No it is not a copyrighted issue these are not copied DVDs. Please read the rest of the post before making suggestions and you will see that these are DVDs we have been using just fine up till now. We have tried many DVDs and have verified that they are still playable in our other player. Also, the problem described above only effects video. When we ran the cleaning disk it worked great and played the audio tracks no problem. The player also has no problem playing music CDs still. It only ejects and shuts down when we try to play a movie or other disk with video on it.

    Likah says "maybe you have defective pick up laser lens, or defective flex ribbon
    wire, this parts need manually replace first the flex ribbon wire".

    Thanks, I am willing to try replacing these. Where might I look for the parts I need? Are there retail sources for these items?

    Also someone else said it might be the ic. What is that is dumb people speak? I need a littler bit clearer an idea of what I am looking for if I am going to order parts.

It sounds like your DVD firmware need to be reinstalled. If it was a lens problem the unit won't shut down, and usually does not read from start.

Unfortunately Phinlips does not distribute firmware for this model (see: Where can I find the firmware upgrade?) The only source to
get the firmware reinstalled is an authorized philips repairer.

The guys posting here also say that they have the firmware download for your model, I would ensure by calling Philips before risking to damage the unit by insttalling the wrong Firmware.

Hi!

Check for the capacitors on the power supply, they might be swollen and are causing this issue.

Mam how about looking at the settings of the system of your dvd and configure the issue from not loading well or you can refer the manual of it. Sometimes it occurs on the dvd itself

Hi, Did if you think overheating is a problem, try running it in open and see if it plays for little longer.
Power units normally get heated up. To compensate it, heat sinks are used in them.
So, I think overheating might not be a problem.

Did you try with different DVDs? are you sure you are using proper DVD format for playing?
Do you remember how this problem started all of a sudden?

The problem is in the the video processing circuits, "thought" change your audio/video cord to see it that will help. If no change! it is far cheaper to replace the whole player, last thought hook to a second TV just to be sure.

Vcr only plays in black and white


Hi Ryana,

Check if the recorder is set to output in 'S-Video' or 'SuperVideo' mode, if your TV doesn't understand S-Video you'll get a grainy B&W picture. The VCR should be set to output in PAL for the UK and most of Europe.

Hope this helps

Dvd wont eject


Make sure the DVD player is level, and that there is nothing stuck inside. You might have to GENTLY nudge the door, with a careful prying motion. If it still won't eject, and you feel daring, you can open the device with the POWER OFF, (Don't lose screws), and see if it there is an obstruction. This last option will most probably void the warranty, so only do this if you are comfortable.
