[HELP]LS670 Screen On my VM670... black recovery+boot screens

[drezliok]

All the new kernels and recoveries should have both screen drivers in them. That's why I was using Jerry's latest green recovery. On top of that its a similar but different problem. The boot logo, second logo, and animation are all black. The animation can be seen if I hit he power button twice at the right moment.

So the drivers are there, I just have a unique situation being the only V with the old screen replaced by an S's new screen.

I should have mentioned before that I ran the update for the radio and firmware already and have no trouble with it.

The phone knows it has the new screen.

If you can find schematics on the two screen pin arrangement I suspect there is something that is just out of whack. I might be off in far right field but I seen a post on another device that the replacement device was wired different than the OEM.

If that is indeed the case I don't think I can do anything about it.

I took a LCD from an Optimus M and it was a novitek (sp?). But it did the same as the OS screen. Once booted it was a nice screen but the recovery was still black.


My options are either switch to a different V or buy a new different phone.
