Dear Members,
I am having the 13/18 switching fault in my Skystar-2 PCI.v2.6d. Always i am getting 18 Volts output to LNB, so i am unable to tune the vertical tramsponders in C-Band. Please any one may provide the schematic for the above.

Dear BombedOne,
Thanks for your reply.
But in the diagram it belongs to Skystar-2 V2.6b. power supply.
Is there any difference in power supply between V2.6b & V2.6d
 
Yes, it's same, just tuner module is different.

Dear BombedOne,
Thanks, I will try to solve the problem for switching 18V to 14V.
 
Generaly you need to replace Q6 (as on above schematics). Better to use some more powerfull MOSFET.

Dear BombedOne.
Can you recommend any specific MOSFET for the replacement.
Thanks in advance.

Dear BombedOne,
Please mention the (Manufacturer & Number) of some more powerfull MOSFET, for replacement of existing MOSFET in Skystar V.2.6d.
Your help in this regard is very much expected.
Sorry for my poor English
 
If you already can't guess, that means that your electronics knowledge is very poor, so to avoid future damage to card, it'll be better to show it to some specialist.
 
Hello, Cheers
I Have a Technisat Sky 2.6D
My Problem is C70 SMD Capacitor On Board Disparted And Missing and I can guess its capacity
Please Help Me and Tell me The Capacity Of C70 SMD Capacitor
Thank you very much your for your help

I'm looking at a Skystar 2.6B diagram. Is there an R22 20k resistor connected to one leg of it going to U7 pin2?
 
Yes that's the frequency compensation series network for the step-up converter chip. Should be a 10nF capacitor.
