SOURCE: dvd "unknown disc" message coming up

Have you tryed to use a lens cleaning disc yet. The laser lens on these players and recorders alike, must have the lens cleaned every oince in awhile. If that does not help, most likly you have a bad laser pickup assembly and you will need to replace the plaer as to have that repaiered, you could buy a new unit. Good Luck

SOURCE: DVD player recorder won't read or play any disc

This just worked for me. Don't know how long it will last though. I found it on this webpage
http://forum.ecoustics.com/bbs/messages/15118/130292.html

To do a reset:
On the remote control press the SETUP button,
Press the right key on the remote 3 times,
The Preference page will show up,
Press the down arrow five time to highlight
"default", hit right arrow to highlight "reset"
Press enter to reset. Turn off/on machine, etc.

SOURCE: my portable dvd player shows no disc when i put my dvd in player

Hi....
Very lightly clean the laser lens ( looks like a very small eyepiece)
with 91% or better alcohol on a swab. Then very lightly dry it off.
Also..have you tried another DVD or CD in it?
Check for dust or debris in where the laser pickup is

SOURCE: my dvd player plays cds but wont play dvds says

Hello,

how long have you been using this player? The problem should be from the lens (laser).

The lens is weak and that's why it cannot read/load DVD's. The weak lens is also what's making it says "disc error" or "Unknown disc". It can still play Cd's because, Cd's does not contain large files, unlike DVD's.

Get a lens cleaner and use it to clean the lens, but if the lens still does the same thing even after using the lens cleaner, then it means you would have to change the whole lens completely to a brand new one.

By so doing your player would play all DVD's with no problem at all.

Good luck.

Philips Blu Ray Model HTS3541/F7 Unknown Disc error


Check with an other known good disc. If it shows the same for that disc too, its laser pickup unit has the fault, and should be replaced. Contact any experienced service technician. Replacing laser pickup assembly to blu-ray players are a very very skilled work. http://electronicshelponline.blogspot.com/

I have an older DVD player. COBY DVD-404. I downloaded pictures from my camera to my computer onto a DVD-R disc and then again onto a DVD+RW disc. Neither disc would play on my player. It comes up on...


Your 'old' DVD player is the problem. It is unable to 'read' picture files. Time to put the COBY away and upgrade to a DVD player that can read .jpg, .jpeg images. Most new players do and they are not that expensive.

My 2 1/2 year old LG dvd/vcr recorder will play some dvds but will not play others. It says unknown disc. I was told to try a lens cleaner; I bought one and the lens cleaner says unknown disc as well. ...


Hi,

Your DVD /VCR says unknown disc because the
dvd which you have inserted is not of the supported format by player.

If you insert unsupported formats only it will say as unknown disc.This is not related with disc cleaners.

Please insert the supported formats and it will play the disc.

Thanx

Unknown disk error when putting disk in player.


hello,

when the disc player shows unknown disc error, it simply implies that the lens of the player is weak and cannot read the disc.

the solution is for you to try to clean the lens with a lens cleaner or better still replace the lens.

take care
