[QUOTE="KillingTime, post: 1150291, member: 258557"] Hi, Lost satellite reception yesterday. Both tuners on a single box. 0db signal both tuners. Plugged in another receiver, no reception so it's either the LNB or switch or the dish has been moved. Not had any windy weather. Checked the power supply on the switch, OK. Sat box is working as I can play HDD movies on it. Other than just replacing the quattro LNB, is there any way to test it? I tried putting a satellite meter in between the LNB and switch to see if it was outputting anything and got nothing but there's no DC voltage output on the switch to the LNB, like there would be with just a regular single port LNB (13/19v), so there's nothing to power the meter (it didn't light up). One other thing, I put a DVM on the sat input of my normal receiver and didn't get any DC voltage either while on the 'Signal Finder' menu. I do get 13v on the 'backup' receiver. Could be looking at multiple failures here. Thanks. [/QUOTE]
