quad LNB

[ll40]

Do LNB's go bad.
I have a quad LNB pointing at sats 110 and 119. Sat 110 is fine, I'm not getting all the transponders on sat 119. I'm missing ESPN, Animal Channel, TNT and a few other channel from Sat 119.
Should I replace the LNB or am I having a different problem?

Perform a check switch test and post the results......

LNB drift?

 

[webbydude]

....or line of sight/foliage issues.

How many and what model receiver?

Those channels are on EVEN transponders. It has been common for people to lose ESPN and such with LNB Drift.

hi i hope this will be a great help missing channels might be caused by no LoS or bad LNB or having LNB drift, first make sure that cables are connected properly on the LNB's and Switch (if you have one) check first system info (if got a DP rcvr's) e.a. 301,311 and etc.... check LNB drift drift value of (e-8) or (e+8) or higher that would be a possible LNB drift, so the LNB went bad but below -8/+8, taht's ok that's just a possible signal loss...run Check switch test and check the result

Depending on receiver model it may only take up to -4/+4 LNB drift to cause issues. As the OP has not posted model numbers I would go with these numbers as the cutoff instead. 381/811 receivers seem to be the most sensitive to this. I can't even count the number of times I have been out to Service calls with 381s or 811s not working and everything else in the house works fine. CS has usually sent the customer a new receiver by the time I got there and you guessed it, the new receiver has the same problem. I replace the Superdish with a dish 500 and the problems go away. I have seen 811/381 receivers affected with LNB drift as low as -3.91

Don't you just love posts with problems but OP never answers questions or posts a followup.

heh, well in fairness, the OP hasn't been back since his post.
So, he hasn't seen the question, nor the answers...
two days...
We often have good answers posted in two hours! -
