Check the cable connections.

Check the cigarette lighter fuse. This same fuse powers both the lighter and the OBDII power supply.

It could be the wires going into the OBD port itself, they can be loose inside the OBD port and reaching behind the plug and wiggling the wire might make the Gryphon turn on and off. If this is the case, use an electrical connector "spoon" to pull the bad wire out, spread the little tab on the wire end and put it back in. A somewhat "cruder" fix is to use part of a tooth pick and push an end of it into the back side of the port on the hole with the loose wire, this tightens up the connection and all is good again. Not an elegant repair, but it works.

I forgot to say that i checked tha fuses and obd port and they are fine.

I understand about the Level, datrevino, but please plug the Gryphon into Pegasus on your PC. It will help Bill to know if the screen lights up when you do this.

The more a device is troubleshot before talking to Bill, the less time he has to spend doing it and the faster you are back in business.

So, if the cigar lighter works, (not the "power point", which is a different fuse), then there is possibly a cable failure to the Gryphon. What year is your truck? Is it a pre-04 model?

You could also have loose or defective wiring in the OBDII port itself.

And, I need clarification - is the screen BLACK or does it light but you can't read the "print"? If it lights, you may need to adjust the contrast: [Menu]->[Display]->[Change LED Color]->Contrast].

Did you recently try to update firmware in the Gryphon? A blank green screen can be the result of a download failure during an attempt to update the Gryphon's firmware which causes the firmware to be erased and not updated. Now, the Bootloader has nothing to boot to, so the screen stays green with nothing else displayed. The vehicle is not at fault.

The cure is to reset a download which reprograms the firmware and calibrations. You'll have to contact PHP for this procedure.

Try this: Adjust the contrast: [Menu]->[Display]->[Change LED Color]->Contrast]. When you move the "dot" into the box next to "Contrast", and hit <Enter>, you'll be able to change the contrast percentage there. Try moving it to a high value, possibly 90% if it is lower than that.

But, if you still can't read the text in the screen after that, it's probable that the firmware is corrupted. Bill has to set up a targeted download for you to fix it, and you'll need to talk to him to arrange that. I'm just a moderator here, and don't have the power to do this step.
