Question about Panasonic Matshita- | UJ-845-B | USB 2.0 | DVD-+RWRAMDL (GPUJ845BU) Burner

MATSHITA UJ-840D, has disappeared and I can't play cd's/dvd's.

I have MATSHITA UJ-840D, microsoft driver version 5.1.2535.0 on my laptop.
It seems to have disappeared and I am not sure how that happened. Up until last week I could play cd's, watch dvd's, rip/burn etc. But now when I put in a cd, the computer makes a sound as if it's reading the cd. It use to automatically start but then it didn't so I went into Windows media player and it's as if I didnt' put a disc in. Even under my computer, it's not showing anything is in the drive.
So I tried to get help on the computer and the location for MATSHITA shows as: 0(0) and there is a '!' in a yellow circle over top of the MATSHITA and a 'code 39: Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.'
Can anyone tell me what is going on?
Thanks

Before you do this though export your current registry to the desktop by selecting export from the file menu. If this doesn’t work just double click on the exported on to restore it.

1. Start Registry Editor by typing regedit into the start search box in the bottom left hand corner of the start menu.
2. In Registry Editor, expand Computer, and then expand HKEY_LOCAL_MACHINE.
3. Expand SYSTEM, and then expand CurrentControlSet.
4. Expand Control, and then expand Class.
5. Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}.
6. In the details pane of Registry Editor, on the right side, click UpperFilters.
7. Right click and select delete
8. Click Yes when you receive the following message: Are you sure you want to delete this value?
9. Now look for LowerFilters in the right hand panel.
10. Right click and select delete
11. Click Yes when you receive the following message: Are you sure you want to delete this value?
12. Exit Registry Editor
13. Restart the machine
It wit worked for me on Acer with UJ845D XP Good luck

    I have I had the same code 39 problem on my HP dv4000 with UJ-40D for months and was going crazy not finding a solution as no standard troubleshooting system would fix it. CVCICLARK, your registry method was THE ANSWER! Many thanks!! I made one slight mod and that was to NOT delete the Upper and Lower filters in the registry but to simply rename them by adding "DEL" to the front end of each filter name for instance changing the "UpperFilters" to "DELUpperFilters". That allowed me to reverse the process easily without a typo in case it didn't work. The BIG QUESTION I have is what caused these disabling entries in the registry? I suspect it was a standard update at some point and I did not catch the result soon enough to make a connection. Do you have any ideas?

Thank you very much cvciclark, your solution worked on my Fujitsu XP as well, but unfortunately after 10 days I have problems again... Now it reads Verbatim data DVD but doesn't open Ridisc data DVD. Both dvds have been burnt on my father's pc and they worked when we made them. Now only the verbatim's are working. The others seem to be empty and don't start on autorun. Can it be the brand (quality)? Some dvds have a closed session but on others we left the session open because there was still space. Can that be the problem? Thanks in advance for your answer!!

Hi,
i,m assuming this is A laptop Computer ?
The only thing you can try is this:-
go to My Computer/Control Panel/ System/Device Manager.
see if there are any yellow triangles or exclamation marks by your problem device. if so click un-install. then at the top of that page, there is a refresh icon or similar. which will rescan the systems bus.
failing this try add new hardware wizard, in control panel.
finally ensure the device is connected correctly, unlock/remove and re-insert. update any device drivers for this.

Matshita uj-840d


Hi, usually and error code in device manager means a sofware conflict with the device. You can try deleting the lower and upper filters in the registry if you feel comfortable. Here are the steps:
1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders

* HKEY_LOCAL_MACHINE
* SYSTEM
* CurrentControlSet
* Control
* Class
* {4D36E965-E325-11CE-
BFC1-08002BE10318}

4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

* UpperFilters
* LowerFilters
* UpperFilters.bak
* LowerFilters.bak

5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer

Purito
