Question about Koss KD250 DVD Player

1 Answer

Koss DVD Tray opens and closes with DVD in correct position, not upside down. DVD worked previously, the previous day, no major damage on DVD surface. Now DVD player continually tries to read the DVD and never succeeds. This occurs on a number of previously functional DVDs. The machine also makes very loud humming noise as it tries this almost like a loud fan spinning up. Any suggestions welcome? Maybe need new unit.

LG RHT 398H. DVD tray not closing, with or without DVD in tray. Tray closes upon request, then immediately opens again, and stays open. Any ideas please? Les

I've dismounted the unit and it seems that I have located the problem. The tray is connected to a wheel, so any displacement is translated into a rotation of this wheel. When the tray is near the close position, it releases a mechanism in order to position the lens. Summarising: if you have pushed the tray with your hand instead of pushing the button open/close, probably you have introduced a desynchonization. To solve this, when the tray is in close position, apply a small rotation to the wheel in order to compensate the desynchronization. There is not an exact position, but you need to try. A few degrees is enough. Regards

My JVC DR-M70 dvd recorder tray won't close.

Sorry for the delay in following up. My tray problem appears to be resolved, but I wanted to wait a few days to see if the problem returned.

After reading several suggestions on various sites for other makes and models, I started experimenting to see if any would work on my machine. I made several failed attempts before hitting on the right sequence of steps. To the best of my memory, THIS is what finally worked for me:

1) I gently pushed the tray back to it's closed position (note: the solution did not work during previous attempts when I left the tray open)
2) I unplugged the machine for 30 seconds,
3) holding down the remote's open/close button, I plugged the machine back in and immediately pressed the stop button on the player, holding both buttons down for 30 seconds.
4) I unplugged the player AGAIN for 30 seconds, then plugged it back in.

A MIRACLE! Upon hitting the open/close button on the remote, this time the tray opened exactly as it should, and it's been behaving itself ever since. I don't know if any of the steps I performed were unneccesary. All I can tell you is that every time I left out a step, it failed. The first time I followed every step, I had success.

As for my remote: I put in fresh batteries. The open/close button still occasionally tells the tray to open and close simultaneously. tvdokter has suggested cleaning it on the inside, but unfortunately, I only see one screw (inside the battery compartment.) I can't see how to get in without breaking it. Oh well, at least I'm back to be able to play and record my dvds.

Anyway, thanks for the advice. I hope this solution will be helpful to someone else down the line. If anyone has any questions or comments, feel free.

Disc tray won't stay closed.

I fixed this by jerking the tray gently. Someone jammed my tray and it skipped a few gear teeth. It seemed like the machine couldn't pull it in far enough to reach its preset position. So I let it close and when it was almost closed, I gently jerked it out to skip the gear teeth back into alignment. It is kind of tricky because the motor will just reverse instead of skipping teeth (you'll hear the plastic clicking when it skips). Perhaps unplug it and slowly push it in manually then **** it back out softly. Just be gentle. Good luck.

LG RH278 HDD/DVD Recorder

I have an LG RH278 HDD/DVD Recorder, which was suffering from the problem that it could not play any bought DVD movies, which were previously working fine in that same player. It would however play svcd and DVD+R/-R movie discs.

The solution was to replace the laser tray. I found a new LG DVD BD lens LPC-815 laser tray here:
I bought two for $5.50 each. Shipping was $32 (DHL), all together $45.10 (PayPal fees included). Delivery was fast and accurate within 3 working days (China - Sweden).

Disc tray doesn´t open, no help from previous answers

One thing you can try is to disassemble unit and remove tray section . on the underneath side of tray is a plastic gear that will allow you to manually bring out the tray thus removing the dvd . then put back together and see if it works ok . Or just may only have to remove the spindle adaptor on the top of the dvd with the screws on the side that hold it down . then remove the dvd , put back together and try . Some disc's that a dvd player cannot read properly can cause the system to lock up as you described . Good luck

Koss KD365 DVD - Says No Disc

Make sure the disc is spinning. This might sound crazy but try turning the whole player upside down and see if it plays.

its inside on the play rack or inside om the disc storage platform.. Nowgetting these bugger sout csn be more harmfull then good so if you ca=nt ubnplug the unit and plug back in and then the unit resets My advice would be to let a pro get them out for ya as I've seen a consumer get out a disk and csuse at least double the damage that cause the stuck disk.
