Channel Signal Loss 004

[Scott Corbett]

Signal Code 12-12-11

I am seeing this message almost every time I turn on my 722K. The normal video returns if I change channels or just wait a couple of minutes. Is it dying?

It indicates your system has a problem not necessarily that the 722K is dying more information is needed for a start how good is your signal strength?

 

[Scott Corbett]

61.5 - 40
72 - 57
77 - 84

61.5 - 40
72 - 57
77 - 84

Those are not your signal strengths each satellite has upto 32 transponders so you have given the signal strength of one transponder from each satellite. From what you have given 84 off 77 and 40 off 61.5 indicates an alignment problem.

My guess is the problem is with the signal to the OTA tuner.

If your 722 is hooked up to an OTA antenna and tuned to a channel that comes and goes, when the OTA signal is lost, it triggers the entire receiver to show a "lost signal" message. This happens on my 622. When you get the "lost signal" message, if you press the guide button or menu or as you said, change the channel, the receiver goes back to working fine.

This bug was introduced in a firmware update about two years ago and it hasn't been fixed.

Just a guess.

No OTA.

No OTA.

look for a DIRT member and PM him or her they are usually helpful. Ray C, Stephenh, Tommy F and Zach S are all showing in RED so they should be available to answer your question now.

Have you ran a check switch test yet?

My bet is lnb drift. I ws having he same problem with my 722. Do a System Info test and see what is reported back in box a. Had my lnb's replaced and no more problem.

ZachS in post #3 Scott indicates his signal strength on 77 is 84 and on 61.5 signal is 40 wouldn't that indicate a skew problem. I know we don't know what transponders he was reading signal from but usually 77 is detuned to maximize 61,5.

I understand and agree that it is low, however a 004 error will appear if there is a problem with the multi-dish switch. This can also be caused by using incompatible or malfunctioning equipment between the receiver and the switch. We are going to need a service technician more than likely but we would want to try to correct it with a check switch test first.
