DB 500HD Tuner Weirdness !!!!!!

[215liverpool]

Hi there

I have an original DM500HD with a motorised dish that has been working fine for over a year now but yesterday seemed to develop this weird problem.

This problem seems to be on the Astra 28.2 channels. Channels which I have previously had no problems watching now come up with the "no tune" message. It mostly seems to be all the Sly HD movies and HD sports channels. The weird thing is that every now and then the picture comes up for a few seconds then breaks up and freezes again.

I thought that maybe my image "Gemini" had become corrupted or it was a drivers problem so I installed the latest OpenPli stable image. I also set up my sat positions again and rescanned 28.2 east but I'm still having the same problems.

As the picture does clear occasionly I'm guessing the tuner is fine and of course half the channels (some of the HD channels too) still work on Astra 28.2.

It makes me think this a software problem more that a hardware problem.

Does anyone have any idea what this might be or have come across this before?

Thanks

i had a similar issue recently with an 800 pro , check your signal values when the error occurs , my "BER" level would rise and "SNR" would fall ,
changed the tuner and not seen any issues since

Thanks for your fast reply.

Yes you are right the signal strength (SNR) bounces up and down.

I've never opened up a dreambox before is it easy to change the tuner and where did you buy your tuner from ?

Many Thanks

Could you try the box on a mates sky dish and see what happens.It would rule out any possible defective cabling or dish and lnb problems at your end.
Least that way you will know its possibly the tuner.

I have just had a look at the specs for my box and tuner is fixed in a genuine 500HD.

Lets hope it not the tuner then otherwise it will have to be sent back to dream multimedia.

As of about 9:30pm last night my box has seemed to return to normal.

On the 28.2 Astra HD channels the dB number is quite high though. Is this normal ? Is high dB better or low dB better ?

Thanks

[southpaw]

High DB is good, fluctuating ber is bad. Ber should be zero
