    Technomate TM-TWIN-OE burned IC SD4841P 67k65yw3j0fz , equivalent IC required

    Hi everyone.
    Few weeks ago I had a power cut in the building and right after that my satellite receiver got broken. The device display does not work, but the HDD it can be heard spinning.The image on TV(via HDMI) got the boot image frozen.
    I opened the lid and I found the burned IC: SD4841P 67k65yw3j0fz which is visible burned.

    I would like to know what equivalent can be installed since the SD4841P it is a bit difficult to find it to local IC store vendors or it takes 2-3 weeks to get it from abroad.
    For example if can be TOP221-227 , TNY264/266-268, TNY274-280P/G and if yes, from the given range which exactly and why.
    Also what can be done to avoid to happen such circumstances.
    Thanks in advance
