I put a DVD in my Digitec DVD player. it says Loading for about 2 minutes and then says no disc with all dvd's but it worked less then 24hours ago

Usually, you either have dust on the laser, so it can't see anything, or you have something on your disc (or damage to the inside part of the disc, which tells the player where all the files are). You can try cleaning your disc, but if you've already tried more than one disc, you might be able to find a CD or DVD cleaning disc at an electronics store. If your DVD player plays CDs, either one might work, but if it doesn't play CDs, then you will have to look for a DVD cleaner. As a last resort, you could try getting a can of electronics dusting spray (don't use a vacuum, as the static from a vacuum can damage electronics) and use several quick sprays, while the DVD player is unplugged. Give it a few minutes to dry out, then give the DVD one more try.

you will have to cleaned use a q tips with wood alcool
dont aply to much pressure on it while wiping it

Normally I would say clean the laser lens, but I actually had the exact same model with the exact same problem, and that didn't work. I was able to get mine to work sometimes by turning it off and on and unplugging it, but even after opening it up, re-lubricating the gears, and replacing a few capacitors near the reader, I never did find a permanent solution.
I guess this isn't what you wanna hear, but I think its an untraceable problem with the motherboard.

Sounds very much like you have a either a dirty laser, or a laser unit failure. Put a cleaning disc through the machine, and see if it improves. If not, then you need to either have a new laser fitted, or a new machine.

check another disk.
or your dvd lens is weak to read dvd
i think it can read cds now.

if not, try to update firm ware or your dvd.

Okay, so I had this problem a few days ago and started watching movies on my X-box 360. Then my X-Box came up with the same error as my DVD player. After reading countless reviews and e-mailing Samsung, I read somewhere that someone had pummeled their X-Box until it adjusted the laser back.

So, I pummeled my DVD and X-Box into oblivion and oddly enough both of them are working. Don't go crazy smacking it but give it some sturdy hits right above the CD tray as you are putting CD's in and opening the tray. Worked for me and hope it helps...

Looks like the lens of the player is dirty or damaged. Try a lens cleaner CD first.

If it doesn't work then you will have to get the lens replaced. Since the Player is still under warranty use while you still can..

I have the same problem. I load the dvd in and after some time it comes up wrong disc. Up until now it has been working well. This is the second coby dvd as i replaced the first one under warrenty with the same problem however it came up with wrong regional disc

I had the same problem but I solved buying "Laser Lens Cleaner " Philips Magnavox after 3 attempts the DVD starts to work fine again. First only 3 min, then 10 min and now the entire CD cleaner and after I left the CD cleaner for 15 min I tried to play the DVD and WORKS!!! perfect!!!

have you tried useing a cd/dvd cleaner disc sounds like the laser is dirty
