I bought this unit from a local junk shop (was used by a defunct provider, SelecTV, and was rebadged SD-2000S for the provider), and upon opening it, C14 (1000uF 16V Luxon LU, on the 7.5V rail, which is also connected to a 5V regulator near the tuners) on the power supply board was bulging and bringing down this rail, subsequently causing unreliable reception.
Replacing this capacitor (along with the others) fixed this problem.
