Hello Old Satellite,
I'm a Language lab engineer and totally new to the satellite world. I've no circuit diagrams, or satellite experience, or any real idea of whats what here! Although I'm generally fine at soldering/repairs, I've no true insight into the fault finding part.
The fault appears to be on the power supply board. When power applied the display flashes off and on (All segments illuminated), whilst a loud fast clicking can be heard.
I was only brought in after the reciever became faulty, so I don't know the firmware, or any other details, that would require power. Apparently the fault started suddenly when they tried to select a different Japanese channel.
I did replace the two larger electrolytic caps as they often cause problems in all sorts of equipment psu's but unfortunately fault is still apparent.
Any light you can shed would be greatly appreciated.
Cheers
Milky
