Solved - LCD not working

[MikeB]

The LCD is connected to the original board using a flat (ribbon) cable. Please check this has not been pulled out of the connector on the original board.

OK, I will do this tomorrow as I am just off to bed.

I should hang my head in shame, I checked the ribbon cable several times when I was trying to get this working. Today I checked it again and it had become slightly dislodged. This time I made sure that it was fully inserted and made sure it stayed that way when I locked the cable in place, and all is working.

Now to do the reverse current protection mod and the ppm protection mod. Can I use a regular diode instead of a SMC one, I realise it won't look as neat but I assume it will still do the job.

As far as the telemetry connection goes I have modified the DJT module internally, so can I just solder the black and white wires to the pins on the backboard.

Once again Mike and João thank you for your help, I don't know what I would do without your help.

You could already have fixed this a couple days ago.. It was suggested precisely that you check the ribbon cable

You can use a normal diode as long as it is a schottky diode, and rated at about 3A (some room here). Be careful not to short anything.. Those boards have a lot of magic smoke trapped inside. Any mistake and they will release it

Good luck, and well done with the LCD..

I agree with you, but this time I did not just use a "Mark 1 eyeball", to check I used the tug on the cable method and found the problem that way.

I will be using a schottky diode and will observe due care to ensure all the magic smoke is retained.

Good luck, and well done with the LCD..

What about the telemetry connection

Dave

If the DJT is modified, then yes, you can do that.. You only need the black wire connected to pin 5. Pin 2 would be only to program the internal alarms of the DJT. I don't think you will use them with the 9xtreme board, as it can do much better, right ??

I would definitely agree with that. Once again thanks for all your help.

One last question re telemetry. If I was to use a Orange Tx module with Lemon telemetry enabled Rx's would I need the white wire connected to pin 2 in this case.

Dave

Which Orange TX module? The one I know doesn't support telemetry.

Maybe it doesn't, I haven't received it yet, but as the one I have for my 9XRPro does I assumed that this one would as well. I guess I will have to wait and see.
