Dissapearing Channels

[Ericktreetops]

I posted about 3 weeks ago that my new HTPC could not find any channels with my existing Hauppauge tuner. In the end it worked after I installed different drivers. But then I lost the channels again.

I’ve own the WinTV-HVR-2205 which I bought 3 years ago and it has given me no trouble. A few weeks ago I moved the pci-e card to a different workstation as I had upgraded my HTPC and was using it to build a second one. Still a windows 10 64 bit workstation.

I left the new pc off for two weeks and unplugged the tv antenna as it's used by my own HTPC. When I switched it all on I again and plugged the antenna back in I found I had no channels again.
The first time I

1. Downloaded some drivers and performed a scan.
   
2. No channels were found. I check card seating and antenna cable without any issues.
   
3. I downloaded the Digital Signal Monitor which said there was no signal.
   
4. However I also downloaded the ProdInfo tool and noticed that some of the dll’s were missing.
   
5. A further search on the internet lead me to a different set of drivers.
   
6. After installing these the card found ALL tv and radio stations.
   
7. Although the Digital Signal Monitor still claimed there was no signal.
   
8. I was able to watch tv successfully through the NextPvr front end, record, load up EPG etc.
   

I switched the HTPC off and unplugged the antenna and returned to it 3 weeks later only to have no signal.
Here is what I tried to do the second time.

2. I removed all drivers from the pc using the clean-up utility.
   
3. I downloaded the latest drivers from the Hauppaugeweb site and installed it successfully https://1drv.ms/u/s!ApXAQQ5XQRNGmRFLsUTQSuFh90Zn
   
4. I rebooted the pc and took a snapshot in the Device Manager. https://1drv.ms/u/s!ApXAQQ5XQRNGmRBAYYPmAgMWFD4o
   
5. I again used the ProdInfo tool and still notice some dll's are missing https://1drv.ms/t/s!ApXAQQ5XQRNGmQ8AAwWJV5zqAhS1
   
6. NextPVR can see the devices here https://1drv.ms/u/s!ApXAQQ5XQRNGmQ6JrsbAXxjMYNWM
   
7. But a scan of the Brisbane bands or even the All Australian bands returns no results here. https://1drv.ms/u/s!ApXAQQ5XQRNGmQ2GYkfxAq4-jdej
   
8. I even had a saved channel xml file to import from my old pc which has all the Brisbane channels and frequencies.
   

I am at a loss as to why I had all the channels and now have no channels again.
Everything points to a driver issue but I have used the latest drivers and the driver I had used for years with out success. Can anyone assist me.

Can you do a scan of 'Australia / all regions', then zip and attach your logs.

Does the device work in the Hauppauge WinTV software that came with the device?

Thanks, I finally worked it out when I unplugged my quad tuner areal cable and used that instead of the shorter one I had used on this new build. Seems that the short cable although looking ok and fitting snugly, for some reason does not work. Well works some of the time as I did have it working before I unplugged it.

Spent two days trying to figure this one out.

Great - good to hear you got to the bottom of it.
