Kworld PE-355-2T Signal Problems

[nightkhaos]

I am having signal problems with my two TV cards for my HTPC and Cy, and I'm trying to work out weather the problem is related to a bad signal in my house, or the TV Card.

Is there anything I can do to check this easily? My idea was to take the HTPC over to a mates place and try it there.

Alternatively does anyone have any experience with this card and do you have problems?

Turns out there is a problem with two of the Coax loops in my house. The one on east side of the house stutters, and has pretty bad signal. That or there is something wrong with the Kworld I put in my case.

The loop in the south of the house has terriable signal, and half the time we can't even get TV from it. But the loop on the west of the house is fine.

On a minor note, every once and a while I boot up and my Kworld isn't registered by the system. In the Device manager it has an explaination, i.e. it had an error when booting. What could cause this? Could this, and the signal problems for that matter, have anything to do with having it sitting right above my graphics card?

I don't want to have to rearrange my case, not least because the only way I can think of gettings this to work involves replacing the D2X with a D2!

My first question, will having the TV card in it's current position cause overheating and stablity problems and would moving it likely fix my hardware error problem and if that is the case, would anyone be interesting in buying a 6 week old D2X for £65? (£85 new)

My second question, would having the TV card in it's current position cause signal problems?

Could be heat....You could try the old take the side off and put a desk fan on it trick. At least that would eliminate the heat issue.

Also from what I have heard sound cards (I don't have one) are notorious for reacting badly to other added cards. Try uninstalling the sound card completely and see what that does for the TV card.

After that, there are some tools you can download to see what your signal strength is like. There's been a thread here opn it, but I'm unable to find it...

I'll do some experimenting tonight to see if I can rule out heat. I certainly hope it's not heat, because moving it to below the graphics card, or to where the Sound Card currently is and replacing the D2X with a D2, will obstruct Airflow for the 295. Not ideal at all.

How can I check if it is the D2X conflicting with it? Are there any signs to look for?

AFAIK - the only way is to uninstall the swine through device manager and see wether it improves.

AVForums may also be worth a bet. Gah - I can't remember who it was who had the same problem, and solved it by selling his old TV card, and replacing with a no-name taiwanese one from Ebay that worked forst time.

Swine? You mean sound card? So what you're saying instead of unistalling the TV card, what I do not when this problem occurs, uninstall both the TV card and the Sound card, and it should (in theory) disappear?

But first, we must rule out heat. Oh sometimes I wish I didn't have a job to do. I wanna fix this now!

I considered that if I do have to order around the cards because of heat, I could in fact put a water cooling loop in, but rough estimates put such an operation at about £200. Kinda expensive, so I do hope this isn't the case. And yes, I did just spec it up, I like to be prepared:

Althrough I may need to get right angle fitting for the waterblock, which will mean I might need change this spec. I'm also not sure if 3/8 tubing is too thick. I'm sure someone can give me some advice if it does come to watercooling the GPU.



Pah just noticed, I would need 6 connectors, not 4! But hey, the right angle connectors and other issues like I have ABSOLUTELY NO experience in the water cooling area means that:

1) I hope to god I don't have to do this.
2) Someone will most likely correct me with better stuff if I do.

[Phage]

Yes. Uninstall the sound card and see whether it improves the TV card.
Watercooling seems a sledgehammer to crack a nut though.

exclamation marks in device manager is usually a driver conflict, try the cheapest and easiest methods first, update the drivers and firmware of the hardware.

and about the signal from the cables being weak, that could be interference from something, do you have any power lines next to the cables?

Thanks mate. I'll update both the D2X and the PE355 if they have later drivers out. Hopefully that'll fix the issue.

Yes there is power next to that coax cable. Not sure as to the internal wireing, but it is likely that that Coax cable is close to the loop that is supplying power to my rig, which can get up to half a kilowatt at times.

The option of course is to get an external ariel. A decent one from Maplin will set me back about £25. This is assuming that the signal problems are not driver related, which is a possiblity.

I will update to. And yes Phage, you're right, but isn't a sledgehammer to crack a nut true of Cy in general?

[vti_786]

new drivers or firmware could cure it, my wifi card on my laptop had signal problems and a driver update from the card manufacturer (rather than laptop manufacturer) fix the issue.

about the power cable being next to your coax, you could always just separate them temperately to see if there is any improvement, rather than spending money and finding out the hard way.

Right-o. I'll just knock a few holes in the wall. It'll be fine, the landlord won't mind at all. The key word in my statement there was "internal wiring".

[nightkhaos]

Fixed it! Problem was the driver conflict with the Xonar, and also heat. The card was sitting just under the Northbridge, so it was a few degrees hotter than it should have been. But it's working fine now. Thanks for your help everyone.

[nightkhaos]

Or not. After watching (good signal) TV for about 5 minutes, I changed the channel and BSOD. Problem does not replicate downstairs, which means the issue is related to running 64bit, or the Xonar. So I'm gonna have too see about replacing it with another card.

Oh joy. this is fun.

[nightkhaos]

Oh you're frelling kidding me. The issue wasn't a conflict between the Xonar and the Kworld. It was a conflict between the Xonar, KWorld AND Realtek HD Audio. Reinstalling ALL THREE fixes the problem.

[nightkhaos]

Okay this is pissing me off, the issue returns after reboot.

[nightkhaos]

*straches head in confusion* Removing the Xonar results in the same issue. Does anyone have any ideas at this point because I'm fresh out. Let's recap:

I am having signal and stablity problems.

The issue can be temporary fixed by reinstalling the drivers for the Xonar, TV Card, and Realtek HD Audio.

Swaping the cards with the one in the HTPC does not fix the issue.

Removing the Xonar does not fix the issue.

Disabling Realtek HD Audio does not fix the issue.

I have the latest drivers for all 3 devices.

The card works perfectly fine with no issues under Windows 7 HP 32bit on the HTPC.
