Is anyone bothered by the fan noise from their 8VSB tuner module? Also, in my case the fan stays on even when the receiver is switched off. I was wondering if this is the case for everyone else!


Thanks.

That's the way it is. It annoyed me enough that I removed the fan and the outer shell/cover from the 8VSB. I took the cover off to allow air flow into the 8VSB. I don't keep anything on top of the 6000. I have not had any sign of anything getting hot.

The only time I hear mine is when everything is turned off, it is barely audible and in no way can it be heard with a movie playing.

Carlos,


Dish will replace it? Even if you bought it online somewhere? Mine does get on my nerves a little.

Schawla,

Is the module from a Dish Network 6000 receiver?, if yes, then Dish will exchange the module.


Good luck.

Del,

Dish is part of Echostar who is actually the manufacturer of the tuner, they replaced mine.

The told me that they sold over 20,000 of them, they know that a few are noisy.

Don't take "no" as their answer, ask for supervisors and the like.

Good luck


Carlos

The noise is from the design not a bad fan. All fans make some noise when running. The thin outer shell amplifies the noise. I keep my PC's in a different room for the same reason.

I'm on my third module. Two were replaced by Dish because of excessive fan noise. I measured the sound level on each using a Radio Shack meter at 72db (1 inch from the fan)! Either I've had a run of bad modules, or there is a design flaw.


If you do a search of this forum on "fan noise" you'll find some earlier experiments trying to reduce the noise.


I tried removing the cover & fan, but after 24 hours I noticed a subtle shifting of the colors on the tv. It's hard to explain, but I would see the flesh tones changing from tan to red to brown, back and forth. Thinking it might be heat related, I unplugged the unit for 24 hours to let it cool off. When I turned it back on, the color shifting was gone until the unit heated back up and the shifting began again. I put the fan back on and the color shifting stopped.


I've done two things which lowered the noise from 72db to 65db: I used duck tape to reinforce the flimsey tin on the module top and put rubber gromets between the fan and module case. I purchased the gromets from Radio Shack.


I've also looked for a replacement fan. There are several on the internet. That's my next experiment.


Hope this helps,

Mike

One thing I did with my PC was to install a large 6" fan on the top of the case. I then used a resistor to reduce the fan speed. This gave me better air flow than a small fan and a lot less noisy.


If removing the fan did not work, I was going to mount a large fan at reduced speed to the top of the 6000. But for me removing the fan and cover did the trick.


I also removed the bottom/side/rear cover assembly. I had to fabricate a little tab to hold the module in place on the rear using just one screw. The first time I took only the top cover off and had some heating problems.


I did not have any color shifting problems. I always watch using the component cables and the colors are excellent.

I think I'm going to try to reduce the fan speed by using a resistor too. I noticed when I removed power to the unit and fan speed dropped, the noise level dropped also. Hopefully I can do this without causing heat related problems again.


Using a bigger fan is a great idea...Are you using any particular brand?


I too only use component cables and agree the color is usually excellent...except when the unit overheated because there was no fan. Perhaps if I removed all of the case as you did and not just the top, it might have kept it from overheating...I'll try that also...
