I have been a Dish customer forever. Last October we upgraded to HD package with the VIP 622 receiver. We had to cut down a huge tree on a hill in order to get the HD package. All was well until the Turbo HD boost. Then we noticed certain (HD only -129 ) stations getting scrambled. It didn't happen all the time so I didn't think much of it until it began happening more often. And then the lost signal message (HD only) would come on often. So we had Dish come out and they said it was another tree blocking the signal. I had them take a picture from the roof of the exact tree causing the problem. Paid $125 for the guy to come out and cut down 2 trees and trim another. I watched the signal strength go from 15 to 30 or better on most transponders for the 129 satellite. Everything seemed to be ok for about 2 weeks and now it is back to scrambled HD stations again. At times if I point the dish to check strength, the receiver freezes. (This did this quite often before the first tech came out. They all say that should not happen, but no one has an answer!) I have to do a reboot. Once I was watching a show in HD on 1, but was recording it on tv 2. It was fine while watching it. When I played it back though, it was scrambled. So I thought it only did it during dvr playback, but no, now it is doing it during Live tv.
Called Dish and they did the check switch routine, which shows everything to be ok. The guy said he didn't like the strength, that high 20-low 30 was not that good. I said listen here, your first tech person told me anything over 17 was fine. Now I have that and I still have problems. The scrambling is weird. Like today, watching a sports channel, the scoreboard on the side of the screen was fine but the players moving on the field were scrambled. Or the top is totally clear and the bottom of the screen is all scrambled. Or just faces and bodies will scramble. I suggested it was the receiver but of course the tech guy said no. He said if it was the receiver, then all the satellites, 110 and 119 would have problems. So he is sending someone out Wed. to adjust the dish again. If they tell me to cut down another tree, I will scream!
I checked every transponder on the 129 satellite, and most are 25-45%. Transponder 2, 6, and 18 are at 17%. Satellite 110 is over 70% and 119 is around 65%.
Any suggestions I can fire back at these guys when they tell me to get the tree guy out here again? Thanks.
 
I am usually the last guy to jump the gun and blame the receiver... but judging by your signal strengths and the behavior you describe I would be inclined to believe it is the receiver.... you probably had a 2 part problem the first time and only 1 problem was resolved.

It could be a bad LNBF too (that wouldn't explain the lockups in the Point Dish screen however).... you could always request that the Tech replaces the LNBF while he is replacing the receiver.... Also, consider evaluating your receiver placement... Dish HD DVRs run HOT.... which can cause a lot of problems if the receiver does not receive proper air flow.
 
now it is back to scrambled HD stations again. At times if I point the dish to check strength, the receiver freezes.

I did have the point dish freeze, for me, after about 10 minutes it would finally get to the point dish screen. After peakng the DISH to 129, that probem went away.

Peak the DISH and the skew using 129, you will lose some signal strength to 50 on 110 and 119

05 = 25
31 = 44

I think you're better off leaving the Dish alone... you could completely misalign it and find yourself with NO channels, waiting for a technician, rather than at least having some of them in the mean time... not to mention it could make it harder for the technician to make an accurate diagnosis of the real problem if you go messing around with things....

It sounds like your dish is pointed incorrectly. If satellite strength on 110 is higher than 119, then your dish is pointed to much toward the 110 or the east (to the left if viewing behind the dish). This would give it higher strength, and would lessen 119 (which is stronger than 110) and would leave 129 "scraping" for what little bit of strength it can get. You must peak the weak satellite without compromising (you'll lose a little) 110.

Look here and you should be able to determine that the trees are or aren't the problem.

The basic concept of your post is correct however the 110 is actually a stronger signal than the 119 as of a couple of weeks ago.
 
I think you're better off leaving the Dish alone... .

Thanks for all the replies. I have no intentions of aligning the dish myself. Unfortunately the tech company called and said they won't have a tech in my area tomorrow, (after this was all arranged on Sunday!). So now I wait until Saturday.
Stations that scrambled last night, Bravo, TLC were ok tonight, but Nat. Geo that has a strength of 36% is still scrambled. TBS, which is transponder 6, and has strength of 16-20% is terribly scrambled. Will be glad when this is all straightened out. Hopefully an alignment will help. I also read they can "peak" a transponder to make it stronger.

The dish was supposedly aligned properly a few weeks ago when they came out and told me I needed to cut down the trees. Said he used his signal meter and got me the best strength he could. (I actually think it made the signal worse.) Maybe with the trees gone he can get it right this time.

The reflector on the Dish is designed so that when peaking, only certain transponder strengths need to be checked.... that is, assuming your reflector isn't bent, dented or severely scratched.

How come some transponders are 30-40% and a few are below 20? I can't imagine a tree branch would block certain transponders. I am so afraid they will say it is a tree again. That seems to be Dish's answer for everything. Never the equipment, but always obstruction. They had my neighbor cut down trees and it was just an alignment problem.

Actually, this is exactly what a tree branch could do... unfortunately, Line of Sight IS and will always be the major limitation of satellite television.

I'm sorry you've had so many problems, but unfortunately, it is tough for Dish Network to keep good technicians around for long... they underpay, offer the worst "benefits" package I have ever seen, and work their technicians into the ground, 10-14 hours a day (I haven't worked less than an 11 hour day in over a year) until they burn out in a few years, max... then they just hire new guys and repeat the process. There are a select few that work the system and play the games to get promoted, but even they are considered expendable by corporate. This translates into a constant stream of new, inexperienced techs that either don't know what they are really doing yet, or techs that are so demoralized by the company's practices and treatment that they just don't give a crap anymore.

I've given you a few tips... hopefully your problem will get solved this next time.
 
Variations in transponders

How come some transponders are 30-40% and a few are below 20? I can't imagine a tree branch would block certain transponders. I am so afraid they will say it is a tree again. That seems to be Dish's answer for everything. Never the equipment, but always obstruction. They had my neighbor cut down trees and it was just an alignment problem.

I have a .9 meter dish(36") self install due to it being a very non-standard dish. It was left over from years ago when I had a sat biz. Anyway to try and finish up this statement. The signal strengths that I get can be as low as 34 all the way up to 70. It just depends on which transponder I'm tuned to at the time. This is due to being out of the "footprint" for the transponder. You will need to go to EKB to see if you should be getting a good SS on the transponder. Examples Tp. 07 which is my lowest is 34 but Smithsonian Channel comes in clean, Tp 30 is 55 Food Network HD, & Tp 16 hovers around 70 ( bunch of SD locals I don't get). Thing is it installer needs to check the dish net signal as well as his SS meter. There also is a good chance that the LNB has problems and needs to be replaced. BTW I have SS on 129 in the same range as I have on 119/110 due to the over sized dish. Get them to peak your dish on 129 and then adjust to have good levels on the other 2.
 
If Dish is going to be launching a new 129 satellite by the end of the year, will it be near the current one? If they keep putting satellites lower and further to the right for me, I will constantly be cutting down trees!
I would guess it will be near the current one or you tech guys will be going out to realign every dish. :eek:

If Nat. Geo is transponder 30 and the strength is over 30, why is it scrambled? I did an experiment last night. Any channel that used transponder 30 was scrambled.
And what may I ask is a EKB? :confused:
Ok, I just figured out what EKB means but no idea where to find the transponder SS you mentioned.

Go to Menu 6,1,3 on your receiver and see if it reports an LNB drift after it runs the test there and you go to DETAILS.

Check if you have any gold barrels in the wiring, they seem to screw with things in the strangest of ways.

As far as the trees go, here's a way you can check that yourself. Go to Satellite Finder / Dish Pointing Calculator with Google Maps | DishPointer.com and enter in your address and there you can set a pointer right where your dish is and it will draw you a line to any satellite you choose. It will also give you the elevation for that satellite. Now, cut you a 2x4 at an angle the same as the elevation angle they give you. Go out by your dish and hold the 2x4 level and look up your cut line to see if any trees are in the vicinity in the direction of that line that dishpointer gave you.

Yes, it did detect a LNB drift. What does that mean?
Tonight channels that came in last night are scrambled. And ones that came in scrambled last night are ok tonight.
Will look into the other suggestions.
Thanks.

Just think of LO Drift as a short inside the LNBF... it is an indication that there is a malfunction. The receiver detects that their is a problem and reports it in the System Info screen. Replace the LNBF and the Drift goes away, more than likely fixing your problem (LO Drift can cause various problems)
 
It says LNB drift detected....
but there is nothing listed under it. I have been reading other posts and they list things like 0x0e, 0xa1, 129(e-7.45) 0o.00
My details list tuner information like
Tuner O, 129 under 4 orbital numbers says 0 0 27 37
Tuner 1, 0 0 29 38

Then it lists values from 0-9.
0-6 are all 0, value 7 is -2 and value 8 is 2, value 9 is 0.
Does this indicate a problem with the LNB?

Yes... sometimes it will not report a value for the LO Drift... the other numbers represent a report of signal levels on certain transponders for each orbital.

Regardless of other issues, your LNBF is malfunctioning.
