I have a Supernet 8000T - PVR set top box, only two months old. Have lost access to all channels after a power blackout. Reset to factory defaults and ran the auto 'search' for available channels but still cannot get any input signals. Accompanying 'User Manual' is useless in this regard as it does not have any troubleshooting guides. Anybody have any suggestions or knowledge of how to reset these things?

I don't know if you tried this but reseting to factory has been a problem for many people. Try the method in the last few posts on this page http://www.dtvforum.info/index.php?showtopic=28705&hl=

Thanks for that Kev,I have solved the problem. The secret is to turn the unit off at the power source AFTER resetting to factory defaults. You can then select country/state etc and successfully search for the available channels. The problem was the user guide omits to mention this vital step.

Yoki

Glad you sorted it out. There have been quite a few people with a similar problem in the past and the full reset is the key. I think there is yet another method but I can't find the relevant posts.

I too have a Supernet 8000T, and originally was able to receive Ch 2 but now says there is no signal for it. Have tried resetting to Factory defaults but no joy...any ideas?

Archer

did you 'save settings' after selecting factory defaults? You then must turn off the unit at the power source for 30 seconds or so. When you turn it on again you then select Country/State etc and search for channels. It should find all channels transmitting in your area.

I recently am having a similar problem. My Supernet 8000T-PVR was getting worse and worse signal untill it was unbareable to watch, I reset factory deafults and followed the steps mentioned in this thread but the unit will still not find any channels at all. I am getting near perfect reception for normal analog so I can't see why there is no signal for digital. The next step I took was to try and reflash the firmware but was getting NO CONNECTION no matter what I tried (all com ports were correct, unit was on... and many other combinations???) NOW here is the real pain, the unit decides when it wants to turn on ?? what the!!! any one had the same problem or know how to fix it???

Hi all- just joined the club.
I have done it all in the last two days:
8000t PVR. Hard drive was half full - could not record, was seen as full. Factory reset - unplug. search channels again. Same problem.
And than I found (I am In Hervey Bay Qld) several new SBS, ABC, Seven and win channels.
I tried them all and found bad to good signal on different channels
I picked the best channel and moved it up as 1 ( I have SBS here) - than all the others as 2 3 4 5 etc.
Channel 1007 had the best seven!
Suggest to search all channels and try every one.
I replaced all coax with quad coax - no more interference at all.
I took the hard drive out and scanned it with Western Digital's software (download from their website -its free) Than I wrote zero's to the drive (takes 9 hours!0
Than verified the disk again as ok.
Back in and flashed the bios with the PRo version. I can now also erase the HDDI have both and will send as attachment if wanted.
Settop box back in service better than new.
5 e-mails over the years direct to German manufacturer Digenius were never answered. The service manual is a joke.

Yep, I too have been having similar problems.
I'll have a solution shortly

Cheers all

For those having problems, please read the following article situated at:

http://www.rjmb.net/pvr-x10/index.htm

It fixed all of my problems.

Cheers all.

(sorry for the double post)

Great - just had a look at the link. All what I have done previously did not solve the problem at all.
Hard drive is reported with all sorts of different messages. I shall try to install a little fan from a computer - maybe it wants fresh air :-)
No answer from Germany
I left the 8000t unplugged over night. Did a reset and scan and programmed - could also erase the hard drive- could not yesterday. My thinking: It is much cooler here over night now. Unit had time to cool down too. All works when it is cool - now I think it would be cool to just ad a fan.

There's only one other thing I forgot to mention.

I've found that these units get really HOT because between the Power Supply circuit board, and the bottom of the case, there is a piece of clear plastic to help insulate from 'possibly' shorting out to the case.
This effectively cuts off ANY circulation in the unit to keep it cool, because it is directly over the ventilation holes at the bottom of the case.
This should be modified by cutting holes in the plastic enough to allow for airflow from bottom to top. Makes SOOOOOO much difference.
There is absolutely no chance of the bottom of the board coming into contact with the case anyway as the space is quite sufficient to prevent this from ever happening anyway.

Good luck....

I have just finished replacing the capacitors in my supernet 8000t-pvr as the http://www.rjmb.net/pvr-x10/index.htm explained and found the following.
- There appear to be some errors in the parts list as I had no 2200uF 25V capacitor and the wiring diagram didn't show this,
- I had no 10uF 63V capacitor and the closest in the wiring diagram was C4, a 10uF 50V (would it be safe to use the 63V version in its place?)
- Changing the C16 and C11 capacitors as they had expanded from heat, this returned full reception and made the unit useable (I also changed C10 but it wasn't faulty)

I will be changing C12 and C15 next as they appear heat affected and the capacitor rating wasn't on the parts list (you need 2x 2200uF 10V 106 degC units). I'll also replace C14 as I'm not getting any responce when I press the red PVR button. After that just flash the firmware for a bigger HDD and fingers crossed it will be back to normal.

oh, also made holes in the plastic insulator like mentioned previously, hope this stops the reoccurance of over heated units.

Yes, sorry about the confusion 6burner.

That report covers the Wintal PVR-X10, BUT generically it is a very similar supply to a broad base of PVR's, including the Supernet 8000T-PVR, from what is pointed out in the article.

I myself, found I only had to replace 2x 2200uF 10V, and 1x 1000uF 16V on the output rails (sorry, the lid's back on, so I can't tell you the exact board part numbers), but the caps in question should be obvious with a DMM, (as per the article's pics) and you sound much more experienced than I do so hopefully you won't have too many problems.

The other point is the ventilation, and I think that is the main problem with these units, and as you've modified your plastic insulation also, hopefully reliability should be improved.

I haven't flashed my firmware, as I have a Mac, and you need a PC to do that I think.

As I don't have permission to disclose the original article's posters email, you can reach him at www.rjmb.net (which I've grabbed from the bottom of his public posting)
I've had a chat with him, and he's a terribly nice bloke, so if you need clarification, try and chat to him too.

Hope that helps.

Cheers

Hi all agan!
Everything I tried did not work - if I programmed to record the recording stopped "hard drive full" - but nothing on it. Will record if pressed on remote to record. I had enough with the digicrystal and bought a YESS
and yes they work - 30 minutes already now :-)
You need an understanding of Chinglish to find out what some strange words in the setup mean.
I will replace the caps in the T8000 and put a 12 V cpu cooling fan in it too - they use milliamps but shall move some air!
Digenus in Germany does not answer any questions - will never buy any products they are involved with!
I wonder if one could not get good parts out of computer power supplies - especially the old AT. They give them away!

Ps: I replaced the coax with Quad coax - all now + 90% signal strength

Cheers all

I replaced the C12 & C15 caps and now the hard drive is back in action working fine again.
I have checked the temps now the plastic insulator has been modded for better air flow and it is only ambient now not even luke-warm.

The full hard drive problem when programmed to turn on is pretty common, a firmware upgrade will fix this
look here

http://www.dtvforum.info/index.php?showtop...amp;hl=supernet

now for the bigger HDD

That's an excellent result 6burner.
Good to see you've resolved the heat issue also.
Glad it's coming together for you.

I still wish I could update my FW, but I got a Mac, so I guess not (for a while, at least)....
Good luck with the bigger HDD, and I hope it gives a few extra years of reliable use.

Cheers all.

Thanks for the great information. I have a Supernet 2120T which had similar problems, losing channels not finding the hard drive. It was fixed for a while by unplugging from the power then re-connecting.
I replaced 7 capacitors in the power supply some with larger voltages, 4 of the capacitors were bulging at the top but the rest looked perfect but for the small cost I replaced all 7.It now works perfectly the below link was very helpful.

Very much appreciated the link and all your information.
