Resurrecting a Humax PVR9200
I was trying to set up a Humax PVR that I've not used recently, to see if it still works. With an aerial lead plugged into the PVR, then a loop out into the TV, the TV gets a signal and works fine. But when trying to tune the PVR in, all I get is an on screen message saying "Bad or Missing Signal". Presumably the signal is getting in and back out of the PVR or the TV wouldn't work, but what might be wrong with the PVR? Thanks in advance.

There's a quirk in the way that digital tuning works on most TVs and PVRs. After tuning the first time, the set will remember the channels that contain signal. Retuning simply scans those individual channels. You have to reset the PVR to its default (factory) condition if you want it to do a full channel scan.

When mendip moved its chs around last time the tv-dvd combi in the old folks home where my Dad was didn't work by simply re-scanning. I had to use the factory reset function to get it to work. Not sure what make it was.

Neither of my Humax PVRs (9150 & Fox-T2) work as described above.
Every single time I have done a retune on either they have scanned the entire UHF band from 21 to 69. I have never had to do a default settings on either prior to retuning. Not even at DSO when the UHF channels of the muxes changed. The only reason I can think of for just scanning the existing stored UHF channels would be to do a "add new channels" scan rather than a full retune. |

That seems a lot more complicated than just selecting factory default
![]() Just adding channels (with either an automatic or a manual channel scan) does not remove existing channels that may be from different transmitters. A defaults setting is the best way to be sure no unwanted channels are stored. Then the automatic scan must be interrupted, and manual scan used on only the known wanted frequencies. Subsequently, being tuned to channels from multiple regions can be eliminated as a cause for accurate recording failures. |

That could be interesting, seeing as I was trying to do it in our caravan, miles from home where it was last tuned in...

![]() The instructions arose because so many people were having issues with retuning from the changes pre DSO, so they provide a clear way to avoid the pitfalls. The OP's position is akin to this. |
