Was away for few days. This evening I connected my board to the power supply and then turned on the psu. My board will not turn on. Single blue flash and that's it. Push the power button and same single flash. When I quit a week ago, I shut down card before turning off psu and disconnecting all wires. PSU shows 5.19 volts at connection point as well as at the card connections. If I disconnect the psu and connect to my computer for power I get the same result

are any of the green lights where the fuses are lit up at all ?

Do have a multi meter. Do you have any photos of your setup ?

Pull the pixels, and disconnect from the PSU. Try just a USB cable from your computer. If that doesn't work, pull the Pockect Beagle, reconnect to your computer's USB, wait five minutes, and try access FPP via the USB network address. Let us know where in this sequence it works, or if it all fails.

All green lights are on(4) at the ports. Multimeter voltage at psu s 5.17. Same voltage at controller outputs. Only 1 pic from a week ago when it did work. Psu plugged into surge protector. Control card connected to psu, stood vertical to avoid heat build up. 1 3ft strip of 2812 lights connected to first output.

Will not connect through ip address. When connected to usb port, I cant even get the blue power light to flash when power button is pushed. It will flash when connected to psu. Thinking it is dead and need to see if kulp will give me a replacement after 2 1/2 weeks or buy a new one. Thanks

The lights on the Pocket Beagle can be disabled through FPP. That's why I went through a complete PB + K4 diagnostic to this point.

If I remember correctly from another post, connecting both the USB cable and PSU can stress the boards. Powering a circuit on also stresses the electronics. Electronics stressed by having been improperly powered will often result in later failures when the electronics are powered up in the future. Power on is the time most failures will occur.

Yes I thought that back then when I said it was scorching hot. I just ordered a pocket beagle from digi-key for 25.00. I have the board. Might as well use it. Thanks
