Circuit board disabled CB124 - 7 flashes

[Jakedugmore]

The DNG is flashing 7 times indicating that the photocells have an issue and preventing the gates from working even though no photocells are fitted! The system has been working for 2 years with no problem, last weekend I tried to program in a 3rd remote, this seemed to stopped the other two remotes from working and the DNG started flashing 7 times.

I have tried resetting to factory settings by pressing P3 for ten seconds. I have tried reprogramming the other remotes. Turning the power on and off but nothing is working.

I can make the gates open and close by pressing 1,2,3 simultaneously and then P1 or P2 but once the yellow learn lights goes out after 20 seconds the DGN red lights starts flashing again 7 times.

Can anyone offer any advice? I have read in another thread that if no ohotocells are fitted you need to add a link into Photo1 and the Com, is this correct? If so, why has the system worked for 2 years!

I am tearing my hair out as nothing seems to be fixing this!

Long time ago but did you ever solve the problem ?have similar problem with liftmaster SCS200 / Chamberlain TPD10. Just blinks 7 times but not photocells are connected even. Pressing P2 and then P3 to remove auto close doesn't help.

Hi, 

If you are not using photocells have you got dipswitch 5 off and have you linked out all the photocell terminals?

I Did contact Chamberlain in the end. Aand apparently I was just dumb, for some reason my new PCBs blinks 7 times before it is programmed, so it was no fault.

Hi,
