Hi to all. I'm new here.
I purchased the dish 500 a few yrs ago. Recently a tech came out and installed a new dish on a pole in the ground to enable me to receive the local channels. (don't know what it's called). I have 2 receivers and 3 tv's. For the past 2-3 weeks, I can only get local channels and channels 188, 185, 109. I checked both receivers and the channels that DO come through are on satellite 110 and transponder 2 or 11.
All channels that show "error 002" are on satellite 119 with various transponder #'s...13, 14, etc.

My receivers are model: DP301

When I did the test, the following was the result:

LNB Drift detected: DP34

Status: check details for "LNB"

Warning 836: check switch test found fewer satellites than previously detected.

LNB Drift Detected:
oxod, oxa1, 110(e - 7)

Switch Status:
Connected to a DP34 with 3 inputs.
Port 1: DP dual - 2 119
Port 2: DP dual - 1 110
Port 3: DP feed 105

Only a week ago, for example, I could leave it on channel 205(Fox News) with the error 002 displayed......yet after 3 or 4 hours it would come back on for a few hours, then back out. Now it won't come in at all. Any channel that shows satellite 119 has no signal at all when I check it.

Below are some of the things I think possibly might be causing or contributing to my problem:

We've had some strong winds and storms the past few weeks, but all the channels would later come back in, until recently. Also it looks like the dish is turned to the right more than what I remember it being. Yet it's tight, and I don't see how it could have turned. But it's not pointed directly straight toward the southern sky as much as before.
Surely, one of my grandsons (ages 5yrs and 7yrs) couldn't have turned it some while playing in the area. Should I loosen it and turn it back to the left some and see if that fixes it?

Also I was cleaning under the cable wires one day and suddenly the tv got a fuzzy picture. When I moved the wires again it cleared up. Obviously I have a loose and/or bad cable or connection somewhere and I haven't fixed it yet.

My system is a few years old, but I had the LNB replaced with a new one approximately 2 to 3 yrs ago. Is it time for this one to go bad too?

I don't know if tree limbs could be blocking the view. Standing behind the dish, there are tree limbs that may have grown into the view on the right side only.

I can't afford to have a tech come out.
Based on all these facts, and the facts I'm not aware of, what is likely the cause?

Also, does the LNB Drifted 110(e-7) mean I'm about to loose the few channels I have left?

Any information and thoughts given are very much appreciated.

frustrated,
Connie
