    If you take your time you can fix it

    just to confirm its pin 3 you lift so if your looking at the chip with the indent notch on the bottom you count from the right side and its the 3rd one up as seen in the pic ,ant you can earth it on the part where the screws go
    an any body confirm please?

    You answered your own question

    As per the original instructions:

    "by inserting the card ... we trigger the micro contact of the reader socket and enable the 'voltage' to turn-on ... we can then measure between pins C1 and C5 which are clearly marked on the PCB ..."

    Default Octagon SF918 Smart Card Reader 3V Mod.

    I have confirmed that the Octagon SF918 Smart Card Reader Chip ST8004C runs the card at 5 volts... this is measured with a DMM at points 'C1' (High = 5v) and 'C5' (Low = GND) on the printed circuit board, see photos below.

    The fix is to carefully de-solder and lift the IC Pin 3 leg up from the PCB track and then solder on a small wire to Pin 3 leg and jumper it to C5 GND (IC Pin 3 leg must NOT touch the original PCB track). This mod will cause the IC ST8004C to run the card voltage at 3volts and whitey will run cool. I have attached the technical data file for this chip for those that are interested.



    Do NOT cut the PCB track for IC Pin 3 as you would for a Openbox X-810 or similar STB as this will stop the card reader working completely. You can see in the photos that I did this by mistake and had to solder a jumper wire across the gap in the track.

    Also thank you AL for your help with this... you know who you are!!

    Wonderfull information,I had nearly started soldering diods and resistors from previous posts but after reading this and checking out the document on the card reader i have found from testing my Vcc output (obtained from following the text) that i appear to be already sending 3.3V to my card.
    I would say the latest firmwear has already lowered the voltage and my "brown" whitey card is damage already sustained to it prior to loading the firmwear. The card is still warmish to touch but no different to the warmth in the whole Box anyway.
    glad to get hold of the document on the card reader chip

    Default Arion AF2000-CICR Smart Card Reader 3V Mod.

    Hello,

    i opened my Arion AF2000-CICR Receiver, which also have a internal smartcard reader, and was happy to see that this receiver has a similar Smartcard IC and is also able to be modded to 3V Vcc.

    The used chip here is a 73S8024RN. You can find it if you follow the white cable from the cardreader slot to the mainboard, its directly under the white cable plug. To switch from 5V to 3v, perform the same action a described above. Disconnect Pin3 (be carefull!!) of the IC from the PCB and then connect Pin3 (5V3V) with Pin14 (GND).

    Hopefully the Card will now run much cooler, we will see...

    which STB is this?

    also has anyone tryed this mod by cutting the pcb track to pin 3 and switching it to GND or the original track (to save lifting the delicate pins on the IC) on a strong 4658x?

    cheers.

    I think there is a track which runs from the pad of the pin under the chip.

    Wink Pin #3 and #1 are joined at 5 Volts.

    G'Day,
    It was investigated at the time when this mod was suggested.
    However it was found that #1 and #3 are joined and that it was impracticable to cut the track to isolate #3.
    Not very clear here, but I think you can get the idea.
    Looks like whom-so-ever did this actually cut the track before finding it was joined to #1.
    Kindest Regards, " The Druid ".

    cheers, looks like pin lifting is the way to go! thanks for clearing that up, its hard to see what goes on under the chip.

    now to find that soldering iron...

    Pin lifting is easy. Check out the video on page 4.
    By reading this, you have already given me control over a tiny slice of your mind

    fixitdearhenry,

    are you sure the firmware altered the voltage? which STB are you using?

    G'day.
    During the recent attack on non-subscriber cards, the conclusion was reached that the card processor was being overloaded with false EMMs which eventually killed the cards as well as causing overheating.
    The so called gamma cards are essentially a 3 V card, but will run cool if not overloaded.
    The problem with making the reader 3 V is that it precludes using other cards unless you make it switchable. Not to be done while STB is on.

    Success!!

    Thanks for the help guys, I now have a fully switchable Strong 4658x.

    The card reader board even has a convenient spare hole to mount the switch in (a $2 cheapy from Jaycar.)

    Common post goes to the lifted Pin 3, one side goes to the pad it was previously soldered to and the other side goes to pin 14. Works a treat!
