sAT.: EechostarDVB 1000Ci2 (no 7 tears old and faulty), one Analogue receiver threshold -3dB, even older but still in good working order, 3.6m mesh dish with positioner, California feedhorn with mech. polarizer and C- and Ku- Band LNBs.

Hi
My now > 7 Year old dig. receiver is on strike or nearly dead.

I switched the other day the receiver on and as no picture came, I saw an "Err" displayed at the receivers LCD display - an Error signal.
After a while I discovered no power for the LNBs (zero Volts at C and Ku Band and irrespective of polarisation).
I'm in electronics (but not UHF), so I opened the receiver for the 1st time.
I discovered soon that the switched mode power supply (PS) switches off.
The sequence is like that: switch mains on
the scan for a signal starts but after 2-5 seconds "Err" comes on. If you leave it, the display changes to time, like you switch the receiver with the remote off.
The time works.
As with TVs, the PS waits apparently for a feedback signal to continue with the operation. As it looks, this his signal is missing and the PS switches therefore off. Only the supply voltage for the clock remains on (separate +5V supply).
The supply to the LNBs is going via a relay and via a series transistor to the tuner. Both are in order. The transistor is controlled from a large chip, most probably the CPU (controlling processor unit) and from there is also no signal.
The relay gets a very short signal to the coil, but then the PS switches off.
What I need is a circuit diagram (schematics), or better the service manual. I bought the receiver more than 7 Years ago in Munich, during a trip to Europe.
The best source would be a web address, where I could download these.
Or a postal address. I think after 7 years, Echostar wouldn’t mind that I get a copy. Of course with a current marketed receiver, it would be another story.
Anyone having some info for me, please?
Thanks & Regards
