Winds tipped over Dish

USA, 62305
We have a dp PLUS dish that is on a flat roof and weighted with concrete blocks. High winds tipped it over about a month ago. I want to realign the dish. I live in 62301 (39.932939, -91.4146). Accessing the dish is a bit of pain due to the top floor of the building being rented, and having to go through that apartment to get to the roof.

The dp PLUS LNBF has 3 horns, two adjacent/conjoined horns on the left and one single horn on the right. It has 1, 2, and 3 output ports, and an LNR input port. The label reads A41C13-5L10004L6. The coax bundle goes down through center of the support arm. The horn weather protectors (1 oval, 1 round) are entirely crumbled and providing no protection any more. Ultimately, I'd either need to replace the covers or buy a new LNBF.

I'm guessing that I'm EA, but I'd like to confirm that. Does anyone recognize the product number on my LNBF. The receiver was set to Sat 77.

Before I realized the horn covers were trashed, I tried to align the dish. I installed Satellite AR and select ECHOSTAR. Then I located satellite 4/1/8, which I think is 77. It was a clear LOS. Then with one guy on the roof slowly rotating the metal frame, and me inside looking for any signal on the 611 menu. I didn't see any signal. I tired other Sats than 77. My assumption is, perhaps incorrect, the dish tipped over, water ran down the horn feeds and entered the RF receiver components and ruined something. Or it could be our aligning procedure was poorly-executed.

I found a low-cost (non-powered) strength meter, which may be helpful.

Suggestions are welcomed.

Stick a fork in it -- the LNB assembly is done.

If the covers were crushed by the impact, you may be doing battle with multiple demons: bent arm, warped dish, bent mount. You cannot straighten a bent/warped reflector. You may be able to replace the mounting bracket if that's all that is bent, but since your access is limited, it may pay dividends to just replace the whole antenna with one that isn't questionable.

You should look into using something much heavier to ballast the non-penetrating mount with.

As always, you should be absolutely certain that the mast is plumb. You can technically align a dish without the mast being plumb, but you'll be doing everything in the blind (the elevation and/or tilt scales will be meaningless).
 
Yup Eastern Arc dish and lnb. 1000.4 for 77, 72.7 & 61.5.. depending on your location you may be able to drop 77 and go with the newer 72.7 and 61.5 dish/lnb. Are your locals on 61.5 or 77?
 
I googled for one of our local channels
10-00 WGEM QUINCY, IL (NBC) - 7712 SD 110° 26s19 A () 5171 HD 61.5° 28s34 A (nbc)
So I'd say 61.5.

Anyone else lose signal on EA?
