Screen corruption problem on CubeRevo Twin Tuner
500 Gb Maxtor disk- Official Image r9580 - DB r9274.

Since several months ago I have been suffering the following problem with my CubeRevo:

It started with a few small green boxes (made of vertical green lines) on the screen, which appeared and disappeared periodically. I did not pay much attention to them at the beginning but days later, there were more and more, keeping for longer time and changing position on the screen. However I noticed that leaving the satellite receiver working for one hour o so they would disappear. It looked that it was able to reset itself to a normal functioning status. All this was happening periodically, every few days.

But weeks later the problem went on to the worse and now the screen is completed distorted, packed with this small stripped (small green vertical lines) boxes, and now with additional white noise boxes all over the screen and with small portions of the image placed in the wrong position overlapping one another. My screen is finally a mess. Sound is always correct.

All this is happing with SD channels, when I try BBC HD, then the screen becomes black, but sound is normal.

I have found that the problem would happen in any channel and also with any recording. Recordings that I had made and watched before with no problems, are now being displayed as described too.

Functions like teletext works in the usual way. The menus on the screen look normal. Radio channels are unaffected. Subtitles look as usual.

At the beginning I tried to justify this issue thinking that it might be a problem with the firmware and I waited for the next release, 9580. After updating the receiver with r9580 I noticed that the problem was coming back again days after.

Thinking that re-installing this firmware might solve the problem, I did it several times from PCEditor and from a memory stick, but it only worked at the beginning and for a short period of time and then the problem reproduced again. Now I am not getting any progress reinstalling r9580. It looks like re-installing does not reset what is causing the problem.

Any help would be appreciated. Thank you in advance.

Seems like 100% hardware issue to me.
Is the fan of the back of the box working? Maye be there is some overheating. Besides that you can only send the box for board replacement.

..I have to agree with arken on this ..
Sounds like you have a faulty video processor ..or a problem with the vpu's addressable memory...
In other words ..a serious Hardware issue ..and not a fault you can fix ..
If your box is under warranty ..I'd make arrangements to have it repaired or replaced ..

Hi there!
My box (IpBox9000 with one DVB-S2 and DVB-T tuner) also suffer from similar problem.

From time to time picture starts repeating 2-5 seconds long sequences, sometimes mix of them with screen divided in 2,3,4 boxes...
(with preety psihodelic effects sometimes :eek: ) ...
... and then gradualy live picture kicks in.

This happens only on Enigma1 and Enigma2 images (all flawors) on satelite tuner. No problems with DGS images or with DVB-T.

At first i was rebooting box, (restart GUI does not help.), but then i discovered that problem dissapear within 1 - 2 minutes.

Video out is through HDMI on LG plasma TV. I also noticed that while image on TV is corrupted, streaming through network works OK.
(I never tried it on SCART ).

I'm totaly confused.
I suspect everything ... from DVB-api, time-shift implementation, HDD, incubus, ... and of course hardware!!!
Did i mention that with DGS images there's no problem? :confused:

sounds like some interference with the picture signal, as someone else suggested try scart instead of hdmi or vice versa, could easily be a faulty lead.

I am afraid that the problem will happen with both, HDMI and SCART, and from satellite signal as well as playing previous correctly recorded files.
