Motorola Signal Booster Damage Receiver or LNBF??

[Bash2]

I did boo boo didnt even realize that i had Signal Booster still connected so I connected RG6 cable to the receiver

I connected my receiver to one of those than to my tv. I might of damage the LBF or receiver i am not getting ANY signal. How can I test if my receiver is bad or LNBF or both?? Signal finder 95 did not show any meter movement. Any suggestions or idea?

Did you try unplugging the receiver for a couple minutes? Sometimes that will fix things.
If that doesn't work, I'd guess that you burned out the part of the power supply that provides the lnbf voltage. Usually those SF95 things will squeal a bit just from the voltage, even when not connected to the lnbf. If no voltage, the receiver might still work in a slaved configuration. I have about 4 receivers (all DTV receivers) that work fine, but don't have any LNBF voltage (I'm convinced that it was an intentional defect).

Connect a multi-meter (set to DC) across the LNBF IN (dish) port of the receiver. The voltage should be 13VDC for vertical channels 18VDC for horizontal channels.

Probably did not damage the power supply, but may have damaged the power regulator or resistors that feed the tuner. Easy fix....

" Did you try unplugging the receiver for a couple minutes? "
YES that worked

Ok here is the problem when I first try portable TV/ receiver outside near the dish I get signal Q 55% but when I hook up my Dish to the house cable which is being used by my cable company (cable is disable for cable company). I hooked my Comcast back and its working. The receiver does not show any signal I thought it was Signal Booster but I think it's something else or both ( Signal booster/ Rf splitters). Again i have no signal whatsoever I turned off the receiver for few minutes and ill try it again. The cable Rg6 coming into my house has like 2 Rf splitters which ones goes to my internet other goes to cable TV than there is another splitter again for different room. I think that might be causing the Qualtiy and Strenght signal.
What u think?? It seems like it just kills all signal all toghter not even a little Strenght showing up on the bar like usual.

You can Not use "splitters" with Satellite signals.

I didn't know that splitter cannot be used by Satellites signals Thanks Lak7 learn something new (still new to Satellite setup). That what's causing the problem with signal drop?? What do you recommend or workaround?? Will the flat RG6 cable work because i have screen door that goes out to the yard I can run the cale that way into the house (cannot drill any holes leasing ).

Check out this thread. General guidelines to watch:
Each LNB connection has a single RG6.
Each Receiver has its own RG6 to it.
If more than one receiver, use this thread to figure out how to get each polarity from each LNB (requires a special LNB).
Do not try to mix systems, ie. OTA, FTA, Subscrition and especially INTERNET TRANSMITTING.

If you can not "drill" a new hole, try to "enlarge" an existing one.
Do a nice neat job, and calk when done, nobody would probably notice.

"enlarge" an existing one"

I will try that option

I have "splitters" on my BUD satellite dish and they work fine. I use the splitters to feed several TV's, but it may not be the kind of "splitter" you are talking about.

Splitters will work on single polarity (or polarotor-controlled polarity) LNBs, such as those found on most BUDs, as long as the splitter is rated at 2 ghz or above. They will also work on stacked LNBs. Most CATV splitters found in homes, however, have a maximum rating of 1 ghz, and therefore will not work for satellite signals. No splitter will work properly (allow proper polarity control) on voltage-controlled LNBs.

I've used the 1 ghz uhf splitters for years, and they *usually* work fine. I've since picked up a couple of the 2 ghz splitters, and while they do work a bit better, I really see very little difference. The signal above 1 ghz does drop off a bit at the high freq end of the band, which would be a problem if we were dealing with weak signals, but these are amplified signals we have here, so it usually won't hurt to lose a bit of signal on the high end. I've actually seen more high end drop-off from the diseqC switches than I have from cheap splitters. But anyway, yes, get the 2 ghz splitters, but if you have regular splitters you can use them, and probably won't notice the difference.
