I had a near lightning strike that took out my receiver, TV, and SWM (in addition to my modem, router, phones, thermostats, oven, etc.) Got a new TV, DirecTV sent me a new receiver, I put in a new SWM and have replaced the lightning arrestor but I'm still not able to see the satellites. I have 20 volts in the cable at the dish so it would seem the cables are still good and this SWM is working. Is there anyway to test the LMB without dropping in a replacement unit? I've found them on Amazon so I'm assuming others have found they also need to replace this component. The dish is called the AV9-SL3-SWM 3 LNB. Thanks for any trouble-shooting hints.
Can I test my LNB?

You're mistaking the power inserter for a SWiM switch. The SWiM switching functionality is built entirely into the LNB assembly. The only way to test it is in place with everything hooked up.
If you've hooked everything up the way it is supposed to be and it doesn't work, your LNB assembly is likely fried.

Thanks for the inputs folks - you're right, it's AU9 and what I called the SWM is the power inserter. I did not know (and the girl at DirecTV did not know) that distinction. I'm ordering a new LNB(F) and the included SWiM switching functionality. Everything else was fried so I've no reason to suspect the LNB(F) was not fried as well.
The lightning arrestor on the internet cable exploded. The white plastic insulation in the lightning arrestor on the cable up to the dish turned black so my guess is it did not entirely do it's job either. Just glad the place did not catch on fire.
Thanks again for the feedback.

And surely model numbers as well. The question that remains is whether these devices are capable of cooperating with an SWiM LNB so that the functionality of the LNB can be fully tested (the goal of this exercise).P Smith said:
I remain convinced that the devices you mentioned are NOT useful diagnostic tools for SWiM LNBs.

You derailed the thread.
OP need simple check functioning of his LNBF - a spectrum analyzer would help him; would be it SA per se or sat tuner card/box capable to produces such spectrogram.
If he need further info, he would ask by himself. Your executive is not based on real use DTV equipment or representing someone who need that checks.

Don't feel bad, he's merely trolling the threads/forums here to see what he can stir up.P Smith said:

How about we quit discussing each other and get back to the topic at hand.

AIM meter will perform an EIV test on the lnbf. Meter is designed for swm and legacy troubleshooting on a directv system. Input your zip code, the type of lnbf, and where you are inserting the meter in the circuit and prepare to be amazed.
