Hello,
previously I am from Germany and my English is not so good.
I have a k8055 Relaiscard. When I turn it on, the LED will light briefly and then go off. The PC will recognize the card any more. Is there a part of what we could replace as?

Please check all ICs are correctly installed - the slot should be according to the printing on the board.
Then check all the soldering. There may be a solder bridge between two soldering points somewhere on the board.
As a test you may remove all the ICs from the board. Connect the USB cable. Is the LED LD11 now lit?
