Same Ole Problem

[Diamond Jim]

I find a channel I want to watch. I enter the FR (Ku usually) into the Qauli TV and get no signal or an intermittent one that won't lock or scan. I unhook the LNB from the splitter and switch and go direct into the receiver and boom, I've got a 71% signal, it locks and the reception is great. What I don't understand is once I get the signal locked and scanned I re hook the LNB through the splitter, switch and back into the receiver and everything is fine. This happens on C band every now and then but is an everyday occurrence on Ku. I have 8 PBS channels stored on the Ku side and don't have any problems when I want to watch them. I have installed new splitters and switch within the last year and everything was fine until about 2 weeks ago. Does any one have any ideas why this is happening?

 

[Mr Tony]

bad cable somewhere between the splitter and the receiver
bad diseqc switch maybe?

Jim I hope you unplug the Q when disconnecting the cable

signal amounts?

Since you got PBS so well, and I imagine it comes in very strong there like it does here on the new bird, I wonder if its the signal strength goofing it? Is the Quali=tv one that only works well with a very strong signal? Since I don't have one I never paid much attention to those threads, just a thought....

How are you connected?
-4DTV --Splitter---DiSEqC Switch---Quali----Loop Thru----Traxis
-4DTV --Splitter---DiSEqC Switch---Traxis----Loop Thru----Quali
-some other way

Is it only the Quali?
Can you try the Traxis to see if it does the same?

 

[Diamond Jim]

I have the LNB going to the splitter then to the switch then to the Quail. The 4DTV is fed off the switch. The Traxis from the splitter to a different switch . I don't have any problems with either of them.

Lak, what is this "loop thru" you mentioned?

Tony, I have changed and switched cables until my finger were sore and I was blue in the face.

I want to ride this out until we get to the new house and the when I install it there I am going to do it from scratch like I just got it.

Most receiver have a loop out option that allows you to hook a 2nd receiver up. This allows 2 receivers to be hooked up to one cable (works great with single LNB setups) On the "main receiver" you would hook a cable to a 2nd receiver and that 2nd receiver gets the same polarity channels as the main receiver. But since you have a C-Band LNB and a 4DTV all other receivers are slaved anyways.

 

[Diamond Jim]

I have seen that output on the receivers, but never paid any attention to it since Rick had me hook it up the way I it have now.

Do you use regular splitter or high frequency splitter.

Do you use regular splitter or high frequency splitter.

High frequency.

I think I am having a servo motor problem. The wires are brittle and I think they have a short somewhere. I touched one of the wires to move it and I could here the motor turn on. If I can touch it and it moves, then do you think the wind could cause it to move? This came up after we had a windy day last week. As of right now everyhing is working fine on both receivers.

My thanks to everyone who replied.

 

[Mr Tony]

wind can definitely be a culprit...

I hope you unplug the Q when disconnecting the cable

Is this some tongue and cheek I don't get, or is there real advice here? I unplug my LNBs and replug them in often. Is there some precaution I should be taking?

Thanks.

 

[Mr Tony]

when adding removing switches its best to power off the receiver with the switch on back. Otherwise you can fry items like switches (done that numerous times), LNB's or even a receiver

so it wasnt tongue in cheek. It was just a valid question. But since Jim has been here for a while that is why I did the option

 

[Diamond Jim]

I am pretty sure that the servo wire is the problem. I was watching PBS for about
20 minutes with no problem, then the video started tiling, I went out and jiggled the wire in question and when I came back in the video was perfect again. Tomorrow I am going to take it off, crack it open and replace the wires. It's been out the for 15 years, so I guess I can't complain.

DJ I just tried that 4130V signal for fun, and I get a 71 on it too, but the quality seems to jump around a bit 35-45, I messed with the dish position and the skew both, and very little movement of skew and it loses the signal totally. Must just be a weak one, I usually get great c-band on this 10' sami.

 

[Diamond Jim]

Servo motor went south this morning. Hope that was the cause of my other problems. Got one on it's way. Should be back up and running by Friday, damn that's a long time.

 

[Diamond Jim]

Problem Solved.

Congratulations Jim!
Now tell us the cure for your mystery.... please!

 

[Diamond Jim]

Due to stupidty I am too embarrassed to tell.

I bet I can guess
