Humax 5400 satellite receiver ,power suppl problem

Hi,
I have a Humax 5400 satellite receiver with a switch mode power supply problem.
The fuse is not blown, the supply attempts to start when the mains power is switched on.

I believe that there is a common fault of 2 electrolytic capacitors on the power supply board drying out which cause this problem.

I don't have a circuit diagram.

I would be pleased if I could get some help in idenitying the 2 electros that could be causing the problem , or any other clues you give me that would help.

Hope you can help.
Thank you
Robert

Dear Robert...


I think the problem with my humax 5400z is similar to yours.

Both 5400 & 5400z have the same power supply unit.

I just solved it this evening by changing C9.

It's a 1500 μF 10V electrolytic capacitor. Be careful not to reverse the polarity my friend.

If you have problems to find the capacitor just e-mail me at rel@link.net and I'll send you pics showing the location of that C9 capacitor on tthe psu board.

Hope this could help you.

Good luck.

Ramez Lebbad.

    I have a humax receiver no power, capacitor 400v 82uf bulge, I replace 400v 180uf but the same not working,

  • denielle libut Feb 23, 2013

    is it no problem even I replace the capacitor 400v 82uf - 400v 180uf?

  • Ramez Lebbad Feb 23, 2013

    Dear Denielle. The power supply of the Humax is very sensitive. Any change of the value of capacitors will affect the power outputs. You should replace the damaged capacitor by a good one having exactly the same capacity and voltage. Just replace the bad one with a new 82uF-400V and it should be working if there is no other other problems. Take care of the polarity too. Good luck.

  • denielle libut Feb 23, 2013

    thanks ramez, but as of now I tried to change the nearest one microfarad which is 100uf, still the same not working

  • Ramez Lebbad Feb 23, 2013

    Try then to change C9 which is 1500uF-10V. This capacitor is frequently damaged in the Humax power supply. Try to find exactley the needed values, not more, not less.

  • denielle libut Feb 24, 2013

    where is the exact location of C9 - 1500uf-10v

  • denielle libut Feb 24, 2013

    could you please help me?

  • Ramez Lebbad Feb 24, 2013

    Denielle In this photo the C9 capacitor has been removed and I replaced it by a red cap of plastic just to show you the location. So it should be inplanted at the place where you see the red cap. Again I remind you to respect the polarity before soldering the new capacitor.

  • Ramez Lebbad Feb 24, 2013

    C9 capacitor location

  • denielle libut Feb 25, 2013

    I check the powersupply of my receiver I think it is not the same I did not found this c9 because this is humax F1-ACE model

  • Ramez Lebbad Feb 25, 2013

    You gave me the impression that you have a Humax 5400 or 5400z. I regret then, I'm not familiar with the power supply of the model you are talking about.

Hold switch is on?


You should just need to push the power switch down from the hold position. When it is pushed all the way up it is in hold mode. Sometimes that switch can break and affect the functionality of the Stiletto. If it is broken, you can contact a repair guy via email at sales@tss-radio.com or you can buy a replacement at http://www.tss-radio.com/products/sirius-stiletto-2-live-portable-receiver-sl2pk1
