I have an issue with a Homepin A-15646 long range opto board for BSD.

The opto is not working when connected to this board. I have replaced the optos and pulled out the board and bench tested it although I am struggling to get the green light to light up. On occassion I get a slight flicker from the green light although I am not able to get a good connection.

I also tried shorting J1 and J2 with a resistor although still only got a flickering green light.

Has anyone had this issue before and if so what was the resolution.

I have contacted Homepin and they have sorted me out.

I would like to mention their excellent customer service. My emails were responded to within the day and they had sorted me out within 2 days.

Highly recommend them as this type of service is hard to come by. Well done and thanks to Mike for all his help.

They replaced the board. I had to undertake some adjustments and testing to the original board and they then sent out a replacement.
