Re: Acer AL1717F blue led does not turn on

It is necessary to check or change all the capacitors in the 5 volt / 3.3 volt / 1.8 volt circuits for new ones . These voltages should be exactly the same and without AC ripples

Re: Acer AL1717F blue led does not turn on

The 3-pin U101 and U102 must have 5 volts ! The 4-pin U101 must have 3.3 volts ! The 4-pin U102 must have a voltage of 1.8 volts. I repeat the question-where did the 11 volts on this board come from ?

Re: Acer AL1717F blue led does not turn on

On a small board (logical with a processor), where did the voltage of 11 volts come from? It only supplies 5 volts ! What is the marking on the U101 and U102 ?
