Question about Coby DVD-233 DVD Player

1 Answer

Invalid disk message sometimes and machine lock up

On several different both purchased and home made dvd's the player sometimes takes a very long time to read the DVD. If this occurs it shows an "Invalid disc" message or can even cause the player to freeze needing it to be turned off at the power point to reset it.

If the freeze doesn't happen and you try a few times it can immediately read the disk and play with no problems

Invalid disc reading

I find that I get the Invalid disk message most likely when I use a DVD-R disk. So now I use only DVD+R for this machine. I have also read somewhere that the problem could be solved by using a Laser Lens Cleaner Cleaning disk.

Disk rotating and a message "invalid disk"

you can try manually cleaning the laser lens ( gently wipe , do not press down hard , it is suspended by fine wires ) using a q-tip and a drop of that cleaning solution you got with the laser lens disc. ( fluff another q-tip a little ) then dry wipe it with another q-tip and try a disc.
you can look at the laser lens and see if you see the laser come on also to determine if that is working ( do not look directly into the laser ! )
if the laser works but it still does not read discs after cleaning it manually , then there is a problem with the focus coil on the laser or the signal board is bad

Disk rotating and a message "invalid disk"

I work for Coby technical support. Our customer service phone number is 1-800-727-3592.

If the unit is showing "invalid disk" on every disk that you try to play, unfortunately, the unit has developed a defect and needs to be replaced. Our warranty is 90 days from the date of purchase. If you've had the player longer than 90 days, I regret to inform you it is out of warranty.

If you feel this solution doesn't deserve a good rating, please let me know why so that I may better assist you. If there is anything more I can do to help, I will!

After formatting the disk, it reads that it is an invalid disk.

I have a Liteon LVW-1107. It is a very tempramental machine. It tends to prefer +R or +RW disks. Will record on -Rs but may fail with them.
On occasion when I insert a store bought DVD movie I will get an
invalid disk warning. The machine seems to get confused.

What I do is pull the power cord and let it set a few minutes.
Give it a little time to reset. Sometimes you have to do this a couple times. It has always worked for me. I hope it will work for you.

Good luck. This is not a top of the line machine.

"Not Valid Disk" message

This Message shows up because it might not be a invalid DVD. Which means the DVD might be scratched, messed up, or sometime when is a DVD that you copied from your computer. Hope it works!

Samsung DVD-4600 DVD/VCR Player

My Smasung DVD/VCR Combo stopped reading DVDs because of a dirty read head. It started by only playing disks sometimes, and progressed to never playing disks. I assumed it was a dirty laser lens so I bought a lens cleaner set. Unfortunately my player wouldn't play the cleaner disk.

So I took it apart and cleaned the laser lens manually with some isopropyl alcohol (the clenser that came with my cleaning disk), and a lens cloth (that came with my glasses). Just open the case (starting with the screws in the back) and remove the snap in cross panel that obscures the lens of the DVD portion. Put a drop of cleanser on the lens and gently wipe it with the cloth.

Oh and by the way, I take no responsibility if you break your own player while following my instructions. My own DVD player was far out of warranty at the time I cracked it open.
