775 Code---Bad LNB Or SWIM Power?

[Rebel Racing]

Hi Guys,

Working on a HR24 with a Slimline Dish. Worked fine Monday night and when we powered in on Tues Morning I get a 775 error. Red button re boot doesn't help. Total power down makes no difference. Checked all connections and all was fine. Equipment is roughly 8-10 yr old. I can access the list of recorded media. I am thinking it is either the LNB or the SWIM power (the light is on). Thoughts??

Thanks!!

Your diagnosis is correct. Do you have any SWM switches? If you just have splitters, trace the power through port 1 (red port) of any splitter in the path from the SWM power supply to the LNB. Reseat all the coax connections. The SWM power should be 18 to 25 volts between the center and shield on any coax going into port 1 of any splitter, and the same voltage should be on the common or upstream port of any splitter. If you can get to the LNB, disconnect the coax and measure the voltage on the coax. If the voltage is getting

It could also be the SWM tuner inside the HR24. If I remember right the last HR24 was made in 2011, they're all on their last legs.

It's actually my Parent's unit that I installed probably 10+ yr ago. As memory serves me I don't think there are any switches inline as it is only for 1 receiver and 1 tv. Once snow clears on the roof I can test voltage at the LNB. Can I check power voltage right at the SWM power supply first to eliminate that?

Thanks!!

Ouch! I hope that is not the issue. Is there anyway (easy) to test that?
