Hello everyboedy. All my soldering is finished. Then i powered up like it is in manual with a mobile USB charger 2A. It didnt power up only all the lights flashed once and nothing else. Is there anything i can check ? I double checked the soldering pins and i can not find any problems. i also tried another charger with more then 2A same like with the other on flash after a couple of seconds and nothing. (Display black and all leds off)
best regards
can you send me photos, this looks like a undervoltage
Here is a short video
try using 5v instead
and make sure that you also check that you didnt accidently soldered or burnt the cable
and make sure its power-delivery(pd) as well,
It is 5V powersupply
can i measure somewhere voltage to check, or can i check something else with multimeter?
try a different cable, and we will go from there
Hey @Karlgott,
You’ll need to fix some of the soldering joints for your Jay-D to work properly.
I’m adding photos of the soldering joints that need to be fixed here.
