Dvd player won't play-shows "bad disc" on screen

I have a Koss DVD player Model: KS4110. I have only used it one time. Ut worked perfectly. I hooked up a differnt TV and had this cheap disc I tried playing. It said "bad disc" so I assumed the disc was bad. I threw it out and three monthes later I rented a DVD from the video store that I know works and the screen on my DVD still says "bad disc" Can you tell me what I can do to correct this?

When I try to use my dvd player I put a disc in it says loading them it comes up and says bad disc, it will also do this if there is no disc inserted into it, can you help me? I don't know the model #...


how long have you been using this player? I suspect the laser (lens) of the player. I think the laser (lens) is weak that's why it cannot read data/files on DVD discs.

To confirm if actually its a laser problem, insert an Audio CD into the player and see if will play. If it plays, then obviously, your laser (lens) is weak. But if it doesn't play Audio CD, then it might still be the laser (lens) or a mechanism problem.

Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.

If non of the above solves the problem, then know that you need to replace the laser to a brand new one.

To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.

Once this us done, your player will play all DVD discs again.

Yours sincerely.

I did a quick search for you and could not find it.
-Might want to think about a new one. Koss's website no longer lists it as a product.

Need Infrared Remote Code...

I had the same problem and it took an act of Congress to solve it. However, I can tell you that through much more hard work and time than it should have taken I discovered the infrared code for my "One-For-All" remote model URC-4021B00 is--0651. Not sure if it's the same for any other remote control models, but give it a shot.

Yes they are surface mounted componets and without a schematic and an ocilliscope I think it will be near impossible to find the trouble if the problem is an IC. If you have access to a scope try tracing the video signal from the RCA output jacks and see where you see it come up. Good Luck
