Frustrated on Satellite TV

It's not that he is unable to set up his Satellite TV for its been 2 years of being used, he's frustrated that its not getting any signal anymore and don't know what suddenly went wrong.

This is the plight of my office mate who has the same Satellite TV set up as mine, I mean very same dish size, LNB and receiver model. Through our conversation on our coffee break (smoking break for us) that we get to know each others satellite set up, although he's been using it longer than I am.
From his description, one night upon turning on the TV, he's not able to get any signal. He check the signal strength on the receiver and was amazed on the signal behavior, normally its value would fluctuate from a value of 55 to 60 but now its range is from 0 to 60, just like an offbeat equalizer. I accommodate him to a retailer in manila, we brought the LNB and the receiver since we think is the only possible device that might be not working properly.

Onto the retailer, we thought that the they must have some device in checking the LNB and Receiver for their analysis of the problem, since they offer repair services. To my surprise, the method is trial and error. They have a fully functioning set up of satellite TV, and what they do is replace each part of what we brought on the functioning set up and check which failed. Well, from the trial it seems that the LNB is still good but the receiver is not. The software is not the issue but the hardware (so they say), they are not sure if they can fix it, my office mate just bought a new receiver with a good discount.

Our initial assessment of the failure would be overused of the receiver cause my office mate said that he normally forgets to turn it off even if the TV is not in used (a possible 24/7 workout, whew!). That's one lesson for our Satellite TV 101, taking care of the receiver means, turning it off when not in used (its pretty basic!).
