    Q2 .... have you searched for service info ... schematic etc ?

    Might help if we could see more of the board. Best I can make out is the chip is marked RT??3AH. The second question mark might be a 5, first question mark looks blown off the chip. Without anything else to help, I'd guess it's a voltage regulator.

    Hello guys.

    Thank you for helping.
    I tried searching the internet, but I could not find information about the board or the IC.
    On the back have these references: ILIPI 021 V.A and 492A00191200H (I think it's also used in HP 2311X (the same or similar))
    Attach two new photos where you can see the remaining components.

    Thank you (sorry for my bad English).
