I'll offer some ideas that you may have already done, so ignore them if this is all old news. Can you access any of the setup controls? (For example, you should be able to press "SPKR" and see the front panel display change as you set the mains, center, and surrounds to large/small/none and the sub to on/off. Likewise, "XOVER" will let you adjust the crossover setting.) If so, that would at least indicate if the 1050's "brains" are still up and running. If that works, the next step would probably be to make sure the inputs are set up correctly - making sure that the input is set to the correct digital input if it is connected with a coaxial or optical digital cable or to the analog input if it connected with stereo analog audio cables (change what an input is set to with the "DIGITAL INPUT" button on the remote while that input is active). Another way to test is to hit the "TEST" button on the remote to get the 1050's internal test tones. If all of those come up empty, I'd suggest giving Outlaw a call - they may be able to help you narrow down the source of the problem.
