Fassl and I have been working on that and the end of the troubles is maybe near, we need testers.
TV and VAIO testers are not required anymore, tests are narrowed to quadro chips.

What we need for TV out fix :
- A dump of your video BIOS
- Your physical connectors layout
- What outputs you intend to use concurrently
EDIT : Now built inside NVEnabler, testers are welcome.

What we need for VAIO black screen :
- A dump of your video BIOS or main BIOS in case they are merged (most likely)
- Your physical connectors layout
EDIT : This method is not applicable to VAIOs, we need a ported version of the linux SNC driver

What we need for NVS 140/570 white screen (found on lenovos) :
- A dump of your video BIOS, you can get it from a system BIOS update, using this utility : Click to view attachment
- Download the BIOS update in .FL1 format.
- Run the utility "e_bcpvpw.exe BIOSFile.FL1 targetfile.rom" => BIOS is now decompressed to targetfile.rom
- Use Phoenix BIOS Editor to open the rom file, ignore the error messages.
- Go to Phoenix BIOS Editor installation directory, there's a Temp folder.
- There are all your ROM modules, including the various Video BIOS (OPROMX.ROM).

WARNING : THE PROCEDURE INVOLVES BIOS FLASHING WHICH IS VERY RISKY ON LAPTOPS
In case something goes wrong your laptop might be dead.
For both desktop or laptop, we recommend you to plane a recovery procedure in case of incident, BEFORE you flash.

For desktop, you need a secondary GFX card that you could use alternately (and that you can plug at the same time, ie if both are PCI-E and you only have 1 PCI-E, it's not ok). If you do, it's not a big deal to bring card back to life.

For laptop, you need to find out if you have an emergency BIOS recovery mode (usually a hotkey, or a special booting way with a media with the stock BIOS, often on the recovery DVD). Some laptops don't have such recovery feature so dead BIOS = dead laptop.

EDIT : Procedure doesn't need flashing anymore

I assume only people who own VAIO laptops with NVidia graphics chipsets are able to help? I would be willing to help if it isn't too risky BTW I have an X3100 in my VAIO.

Yep only Nvidia, anyway ATI users don't have this black screen problem

BIOS image on VAIO can be obtained from an updater by typing its name followed by -writeromfile switch.
eg : D820_A12.exe -writeromfile

VAIO tests failed so far. We definitely need the SNC driver to be ported.

OK, ready to be Guinea Pig

Lenovo T61 7663-CTO 4GB RAM

nVidia Quadro NVS 140M
in Windoze nVidia System Information utility shows 512MB (whole), cannot find out where to check real HW VRAM size
Video BIOS Version: 60.86.3e.00.00

All other Injectors/Patches removed, kept originals form 10.5.7 kernel update, kernel is AnV (Vanilla kernel somehow doesn't work).

DeviceID is added to NVDAResman.kext and NVDANV50hal.kext

NVEnabler shows Wrong BIOS Signature on boot, nothing more happens (gray screen if started without -v parameter).

The Video BIOS has been dumped, zipped and attached as per instructions above.
