[blueangel]

Our 2722 show error (8070) :dsp host vector not available. If it possable I can fix it myself ? Seem no service manual can reference.

Does some one can help ?  I already check all power supply are normal ,and connect checked also. But I don't know DSP HOST VECTOR issue need to check which board.

Thank you very much.

Update....

I found that don't power on AP2722 , Run APP first , when screen show four items and wait for select, then power on AP2722 , and choise 2 or 3 or 4 , AP2722 will work. If choise item 1 ,same error message will pop up.


I don't know what cause it...
