As you may or may not have gathered I got a Nova-HD-S2 a few weeks ago. It worked fine when I got it, then it progressively got worse, until last week it would record 1 program then 'die' (Wouldn't record anything else, live tv said partial lock). A reboot later and it would do the same thing. Now the hard drive in it was dodgy to start with and made some interesting rattling. So got a new hard drive and install mythbuntu 12.04. I installed linux-firmware-nonfree, and that allowed me to scan and watch some channels. Then it died again. Countless reboots and cold boots later I can't even watch live tv after it turns on (Partial lock), or scan for channels (scan command or mythtv backend scan). I have tried the latest firmware which the linux tv wiki suggests, but to no avail. So took my only other desktop in the house down stairs to try in using windows and it corrupts my bios, and the computer won't even boot into BIOS...

So do I return to seller asking for a new one or is there something else I could try first?

Did you get it new? If so, you have warranty on it. If purchased via fleabay or similar, your "warranty" ends on the doorstep. Of the seller Rolling Eyes

So you saying that I should look into returning it?

Sounds like a hardware fault, certainly.
Mind you, the card needs to supply 50VDC for the LNB, so maybe the PSU is a problem?
BY the way, how did you get on with multi-channel recording?

Well the comp which the tuner wouldn't even let boot has 850W PSU, and I took out 1 of my graphics cards and unplugged all bar 1 of my hard drives so that should have been fine.
As for the comp I want to use it in it worked when it first turned up then didn't. Comp still turns on, etc

I can (could) record stuff on the same MUX, (like Channel 5, 5* & 5 USA for example) at the same time, the myth setup only allows you to record 5 things at the same time on 1 tuner but I think the max I recorded was 3, so can be done so long as on the same MUX Very Happy

It couldn't be the actual cable? Does the wire in the middle need to be perfectly straight?

Yes, it does need to be straight, sharp bends and crushing can stop it working.
Coax needs an airspace between the core wire and the braid, that is where the RF signal waveform actually travels, in the dielectric, not in the actual core.
I had a customer install a cable, and when pulling it through the roofspace, they got a kink in it where it had folded back on itself, which totally wiped the signal.

Hmmm, I'm not sure about your explanation here. I thought that once received by an antenna, the signal is no-longer a radio wave but an electrical current of radio frequency, no?

I'm pretty sure that the thick insulation between the core and the braid is to reduce the stray capacitance between the two, thus reducing attenuation in long cable runs, due to RC (or LC) losses.

Well whilst you to argue about how wires work, I have returned to dabs, hopefully I will get a new one soon and find it was the card not the drivers Very Happy

No arguments, just discussions. It's difficult to establish that in print, I know Wink

On a serious note though, good luck with Dabs. I've had bad customer service from them in the (not recent) past re: returning faulty goods that are still under warranty. However, it was over 5 years ago and also since your purchase was made less than 6 months ago, your mileage may vary.
