Over the past few days I've found my s10/90 cm/sg2100 has lost signal on selected sats and tp's but I've made no physical dish changes and all was well before, only a few days ago. Can anyone suggest the most likely cause?

Here's what I seeing. I'm still good with selected tp's at 61W and 125W with good SQ about the same as before but some tp's have dropped. I still get some tp's on 72W but have lost the 4 NBC mux entirely. On 83 RTV/Tuff is still good to watch but off by 15% SQ. For both the LPB channels on 87 and ABC News on 91 I get a picture that immediately freezes with no signal. CCTV is strong on 95 as is History on 101 but both off a tad for strength. Happens with both v and h tp's. I'm suspicious that the dropped tp's are weaker footprint ones for the Toronto area but I've had good "green bar" quality until now.

I've tried bumping the dish e or w on a few sats/tps to see if that helps but makes no difference so don't think the motor/dish assembly has shifted on the mount. The lnb would seem to be good as its still doing both h and v and the S value is still a good 87%. So that leaves me with my elevation having slipped. The area weather has finally gotten colder here (-7C at night but above freezing during the day), so I can speculate what was summer tight may have loosened up enough that wind pushed the dish (hopefully not the roof mount itself) but before I go up on the roof in the cold, does this make any sense?

Hopefully the simple answer is the right answeras I don't want to go on a unicorn hunt. Is elevation the most likely thing to work on?

It would help if we new something about the type and size of dish your using. I can tell you that on RTV and Tuff TV I'm see a Quality of 76% and that's with a 1.2m dish. Like you mentioned I'd be looking at the dish having something lose and moved on you.
If it does turns out to be a lose nut you might look into getting some threadlocker from your local automotive parts store.

Is this on an S10 receiver? Many individuals with an S10 have had strange signal loss and switching problems. Those topics have been discussed quite a bit on this site.

I just had this problem with my Pansat 4500 and i did elevation ad skew adjustments and it is now fine. Many sat techs that i talked to say to take your dish down once a year and readjust it for possible skew, earth, satelite and, elevation.

I would go out and re tweak the dish. What dish are you using, etc.

(Openbox S10/fortec type 90 cm dish/sg2100 motor). Ended up tweaking the dish and got the tp's back. Seems like there is tight and then there is tighter when nuts and bolts are concerned. Elevation was fine. I had replaced my mast a few months ago so it looks like the motor mounting clamp had not quite dug in enough on the fresh painted surface so with colder weather and some recent rain as lubrication, it shifted in the wind. A lot tighter now.
