Faulty Technomate TM-780 receiver - ideas?

    I have a TM-780 receiver that is not picking up any signal (constant 49% strength even when unplugged, no quality at all)...other receivers work fine on the same dish.

    Any idea what might cause this?

    If it's hardware failure any chance of fixing it by swapping out the LNB in/out connector (I have parts from a couple of different receivers, and I can solder).

    It's not unusual to see a signal strength reading on the screen, even in the absence of any signal. Check that the LNB type in the Technomate is set correctly to universal. If it's not set correctly it will either not power the LNB properly or will use the wrong oscillator offset, resulting in no actual signal.

    I figured that when it was giving 49% with the wire out too :) most receivers seem to give at least 80% as long as they are hooked up, so this suggest to me that the actual LNB connection might be faulty.

    LNB was set to "universal" - the whole thing was set up for Hotbird but my dish is pointing at Astra2/Eurobird so after trying to switch satellites without success I went back to factory default to get rid of any setting, but it still won't pick anything up. Cable is fine (other receivers are flawless), tried it on two different lines.

    I have tried setting up transponder manually too.

    Unless there is another weird little setting I haven't thought of it nearly HAS to be hardware....
