    When you have a issue with the vu uno clone ferrari security chip which is mounted on the tuner you could consider to remove the chip and add some wires to it with a socket.
    Then you are be able to use a duo security chip or even a solo chip or yet untested on this box the Japhar Vu J chip.

    I have here the pins information to modify it to a socked version.
    Modification to a Vu+ Duo V3

    Modification to a Vu+ Solo V3

    Modification to a Vu J Japhar

    Of course when you do that, you need remove the syncmos security chip.

    See the vu-duo-v3-security-chip-repair-project for more about the socket pins

    Hi Johnny . i have this chip.its not Vu J ( i dont have one ) ,but i think is from Vu Solo .A bit different from the Vu Duo one . on the Vu Solo chip the model is SM59R16G6 ,W48P,1208B ,NP2751BH . On the tuner is chip is the same accept the last line which is NR4752BH .Can you confirm the pinouts connection , because im seeing them different on the security chip and on the tuner.Thanks

    Hi,
    The differences with this solov3 chip is the first pin, which is not used and the Rx/Tx is swapped.
    The duo v2/v3 chip has the Tx/Rx

    I have here a picture about it,

    ok so now i need to remove the chip from the tuner and solder cables .By any chance do you have of VU SOLO the rs port just to confirm that everything is right there ?

    Terminal output, vubox serial cable with adapter questions.

    What is UPDS and UPDF, and what does it mean?.
    UPDF is a confirmation that the (U1) SYNCMOS security chip that is installed onboard on the print side works.
    UPDS is a confirmation that the (U702) security chip module works.
    Most common problem is the refusal of the UPDS, and often means that the security chip is not working.

    More about this see, vu-box-security-chip-test.
    However, the security chip may still work, but the tuners may fail.
    This may happen due incorrect software or a issue with the chip.

    The U804/U805 are for the tuner, both are the same LD1117 3.3v (output center).
    It's not a difficult part to find, you should find them on other dreamboxes, or other devices.
    In any case, the dm800hd has one.

    Hi Johnny . I found one ld1117 on a small network switch . Replace faulty one and now everything is working . Also i have try the option with cables which works too with no issues.Thanks for the help.

    Cool, well done, nice job that you have found and repaired it.
    And thanks for the confirmation that the wiring works, now you are at least ready to use the future Vu J chip module when it's ready and to use the latest original image files, that is... In my case it's tested with a solo/duo and even the mini duo.
    Online updates etc.. for now no problems.

    Problem again :( . Is this ld1117 have to ve very hot ? i guess no .this morning i found the box with no working channels , restart and now doesnt shows that there is tuner at all . I swith it off. will leave it to cool down and try again .Put old image again to confirm .Yesterday was working for quite some hours :((((.its heat up quite fast , but still gives 3.3V on the output but no tuner

    It's logic that it gives the voltage output while a tuner is not connected because it's a dc to dc regulator which in this case a 5v to 3.3v.

    That it become hot is not normal, especially when a tuner is not connected because as far as I see it they are not going to other parts then the tuner slot.
    The only logic thought I can think of is a shorted cap.

    Normally, if you remove the 5 to 3.3v dc converter and the metal cap you should not measure any value between the ground and this 3.3v circuit.
    With the parts it should be in the K Ohm range,

    I've made a overview from it, you can see it here.

    there is no short to groung or any value from 3.3V to ground .not shorted. but comes hot and the cool and then hot again .like that there is something which makes it overheating.infact i found a small burn damage from the heat :(.

    In that case you may just have bad luck with the 1117.
    There are several types which can handle different amps, Normally it should be 1 amp maybe you have taken a lower version or somehow the circuit ask more than 1 amp.
    But still, it could also be a bad 1117 dc/dc converter.

    These Dc to Dc sot-23 regulators have sometimes a strange behavior when the regulator internally have a low ohm value which may result in a shorted, or hot issue and mostly after a while may the output voltages drop, or even rising.

    The better ones are the good old 5 to 3.3 ic's as the ld33v which has their own heat zink and the same legs connections but they are bigger than the 1117-33

    Nevertheless, when they are healthy then it may not become hot after a while.

    SO far what i found suppling is :
    CT 201,202.203,224
    RT 226,227
    FT202
    and U3 secret chip
    Messuring value without the tuner on the U804 on the board -600 ohms same as new not solder to anything .I have 4.9kohms on the tuner on the 3.3V line.WIth tuner warming up and without tuner cold like ice .
