Re: Invalid disc

From experience you should never touch the lens . If this is last resort then use a q-tip and 90% rubbing alcohol (or higher%) . If that doesn't work my friend it might be time to throw it away or return it.

Sony BDP-BX2 Blu-Ray player now rejects valid discs as "invalid"

Sometimes the latest update IS the problem, not the solution. If possible go back to an earlier version and retry the disks. Many of the answers here about power down and the like are all good and sometimes helpful things to do. They also point to the fact there isn't much a consumer can do to fix or repair malfunctioning DVD/Blu-Ray players and it always comes down to cost. Do you want to repair or replace. You've had your unit, you say, about 3 years? I think this is about end of life. Anyway, try the previous software version and if that works turn automatic update off.

Keep getting "Fail" on blank discs

The LVW-5005 DVD Recorder came with a list of recommended brands for each type of disc, and they are all different in all categories. Some brands are recommended for CDs, some for DVDs, etc. They are not the same in any catagory. Most of the ones I bought were not on the list, because I couldn't find those listed anywhere in my neighborhood here in California. Some worked before, but are not working well now. Some have never worked, and some are failing intermittently.

The INVALID DISC message comes up on both units often, but when it comes up on the LVW-5005 unit the DISC eject feature will not eject. The open close door stays shut and says it is open, but sticks and keeps trying to reread the disc. You actually have to tip the machine down to let gravity help, and then turn it on and off and on and off and it finally opens and drops out the invalid disc.

The LVC-9016G unit says "change disc", or gets stuck on "Preparing". Sometimes it prepares, and then I can actually record, but when I try to load it later..... FAIL! This too is INTERMITTENT. GOD I HATE THAT WORD!!!!

I am not good a taking machines apart, and I have a MAC system 10.5 computer, and the firmware update seems to be geared to the WINDOWS PC. HELP?? Is there anything I can do.

Also IS THERE A LIST OF PREFERRED BRANDS of the media for the LVC-9016G model. It may be the same as the list for the LVW-5005 unit, except the that unit is supposed to record on CDs as well. NOT SURE> None are working consistantly.

The other idea that I had is that the newer DVD-R and DVD-RW or the DVD+R and DVD+RW discs have a heavier technology and these older burners (2 years makes it older, I guess....) and seem to no longer like them.

The 6 hour SLP I always set them to record on in the past, may no longer be valid. The 4x, 8X 16X etc. may not work either. Since I don't understand what that means, and we only have access to what is available to buy, I am at a loss there too. I am logical, but not technically educated in this technology. I come at this with psychology, not technology... :-)

I have the LVC-9016G for 2 years, and the other bought at COSTCO only a year ago. Is $300 worth of equipment already obsolete?

I have not hacked or touched anything. I may need to buy another lense cleaning disc. I have a memorex one, but when I put that in it said INVALID DISC, and will not work either. Won't read or spin.

I am frustrated...

Candy user_offline.gif this can be due to invalid media........all types will not burn in this unit........good success....meder's tv service

Panasonic DVD-RAM "Invalid Disc"

This would suggest the disc is defective, especially when all others work. I would return the other.

Keeps saying 'no disc' or 'invalid disc'

The Laser Pickup Assembly is the problem, the laser eye is weak and can not read the disc. If you take a Q-Tip and rubbing alcohol carefully clean the laser plastic lens allowing several minutes to dry. If after all this there is no change the only option is to replace the entire unit, because the cost of repair would not be justified.

Presidian dvd recorder pdr 3222

Have had the same problem with my Presidian3222 for the last year, if I recorded something it would come back as invalid disc or blank disc or would not close disc out right, got so damn mad almost took a hammer to it last night, unplugged it like clicky said, did no good, thought cable co may have been sending single to screw up recording, but today took camcorder and tried to record something, same thing which seemed to let the cable co off the hook.
the following seemed to have fixed the problem, first open the player then unplug it, close the drawer 1/2 way, then I took compressed air and blew inside the player to clean the laser after that I have been able to record 3 movies and close the disc properly and finalize the disc properly, I even had 50 new disc made by sony that recorded kept saying were invalid, reads them fine now, I hope this helps everyone, because I was on the edge of putting this thing in the trash last night.

LiteOn LVC - 9016G dvd recorder Problem.

throw it in the trash- I got 1 from costco, liked it so much, bought another a week later. First one started giving me the "invalid" msg, 2nd one did the same 1 wk later, so I guess they're programmed to do so after so many hours after being plugged in. Too bad, cuz it was the easiest to use of 5 previous models I tried. Their easyguide onscreen menu was the greatest, plus the status of time, pause & recording indicator, which you could turn on or off as needed, were very useful.
A real shame to have to throw in the trash. Won't ever buy another thing from them.
