Some people have the same problem, as described here: TV Schaltet immer von AV1 weg

Changing the power supply for the new version should most likely help.

If you bought your box 1 year ago, there is still warranty on it. Send it back to dream multimedia and you will get back a proper box.

Hi!

Approx. 1 year ago I bought my DM7025, and have been quite satisfied with it... But a couple of weeks ago, it started to suddenly loose the picture (and sound!) on my TV ?? Both the SCART output and the output on the Phono connectors are blank/quiet.
The box seems to run okay, I can SSH to it, the web interface is working - streaming to VLC is working...

A way to get the picture back, is to power off/on the box (doing it on the remote control is sufficient)....

Could this be a thermal problem ? I've tried to "feel" the temperature on the box, and it seems quite warm on the left side (where the PSU is located), and a warm in the middle (just over where the HDD is located).

Any ideas on what to do ?? The DM7025 has apporx. 8 cm of free air above it, so the heat should be able to get away. The receiver is located on a glass shelf (which is approx. 5 cm over my AV receiver). This setup has been working without problems until a couple of weeks ago...

Regards
/Brian

I seem to have the same problem with my 7025
I can see all menus, all OSD's messages etc and change channels too, but I cannot get any picture/sound from satellites. Is your case exactly the same or do you loose all signal from Scart?

No the exact same problem. I loose picture and sound on SCART and on the phono-plugs. I tried to remove my harddisk from the box, but that didn't solve the problem.
The problem often occur if I swicth to a channel on my DVB-T tuner after have been watching a SAT-channel for e..g 15-20 minutes... After 30-120 seconds I get a blank picture on my TV - and no sound..

Is your TV Panasonic? If so, have look at this thread flickerfix

Could it be memory issue? My problem could be. I installed [Moderator] Image is in violation of the Boardrules [/Moderator] and set 64MB swapfile on hard disc three days ago and I have not lost picture/sound since - knock knock. Depending on what image you have there could be swapfile option for you too. Give it a try.

Ok, guys. Before you post again, read the Board-Rules!!!

I do have similar problems. I have a Dreambox 7025 with one DVB-S and one DVB-T tuner. Coverage of DVB-T is very poor in my area.

If I tune to a DVB-S channel I have a good picture. Next I zap to a DVB-T channel which has poor coverage. The tuner tries to get in sync but gives up. Then I zap back to the DVB-S channel and I have no picture at all. I can zap further to other channels, and no picture. The only way to get a picture again is to reboot the box.

It looks like the poor DVB-T signal messes something-up in the MPEG decoder from which only a reboot can recover.

After digging my problem I think now that I have the same problem. I have weak signal for Thor 1W and if I stay away from Thor picture/sound will not disappear and I can use those other three satellites without problems.

First I though that my problem was memory issue, but swap file didn't help for long. Then I though about heat problem and installed two fans inside the box. Only difference was the noise of those fans, so I took them out.

So could weak signal kill MPEG decoder to state that reboot is the only cure? Restart of Enigma2 is not enough.

I have the same problem with weak signals.

If i zap on Nilesat where the signal is marginal the box will give up trying to bring a picture after a while.

Only solution is to reboot the box to get the picture back.

My box is built April, 2007 so it got the new PSU.

I opened a thread under bug-reports. I think that is where this item belongs. See " Dreambox hangs when signal is poor ". Lots of people seem to have the same problem. Hopefully DreamMulimedia will work on it, and give it priority.
