Widescreen Switching Problem?

[theequalizer]

Ok spent all day on this one, so any help would be appreciated!

My dm500s is setup in 16:9

When a channel switches from 16:9 to 4:3 everything is ok and the image switches to 4:3 on my 16:9 TV.

When a channel switches from 4:3 to 16:9 my tv 'turns off' scart1 input and cycles through inputs.
I then have to manually select scart1 to get the 16:9 picture back.
This can be infuriating on channels like nat geo when the programme may be in 4:3 and ads in 16:9.
This means everytime it goes 4:3 to 16:9 I have to manually select scart1 as input everytime.

If I do this with my freeview box using the SAME scart cable in the same socket, then everything is fine! (4:3 to 16:9,16:9 to 4:3)

So I know it's something to do with the dreambox,but I can't work it out!
Any help???

forgot to add as well when the picture switches back from 16:9 (no picture unless i select it) back to 4:3 the picture comes back on!

have you tried another image,might be a fault in it?

 

[theequalizer]

That was my last choice.

Because I would lose all sats and settings etc.

Also I thought gemini was best, so I wouldn't know which other image to try.

I know it must be something or nothing, thats the infuriating thing.

gemini is a canny image but might be currupt file downloaded. i prefer nabilosat far better in my eyes.

you can back up your channels/bouqets you know then just send them back takes about 2mins and saves time scanning.

have you checked all of settings in menu---setup---system setup---av settings?

yep it's say 16:9.

I know it's something to do with the 16:9 switching.

I've tested the scart and tv and they are ok.

I've givin up for tonight,but i'm going to try again in the morning.

If no-one else has any ideas by tomorrow morning, I may try reflashing the box.

Further to the last I was wondering if the psu is giving enough power/failing.

I have read elsewhere that 12v 1amp psu (which came with my clone box) is no good and you should have a 1.5 or 2 amp psu if it's in use with diseqc motor.

Can anyone verify this? and if you are using a dm500s what amp psu you are using.

 

[krazylegz]

cant really see that being the problem,i always used my dreambox with just a shaver adapter and that always worked ok. have you disabled the wss option in av setting to see if that helps?

 

[theequalizer]

yes tried that and it didn't work.

But this morning it's working ok?!?!?!?

I noticed that the psu isn't whining when I switched it on this morning. (switch it off at night)
It ususally whines for the 1st minute before I switch the box on.

I still think it's something to do with the psu.

Next time it stops working (probably later when i have moved the dish a few times) I may try and get the multimeter on it.

Q: There has been many problems with Dreamboxes power supply. What are they? And how do I address them?
A: Some Dreamboxes come with a 12v 1 amp power supply , this is very weak and may damage your dreambox, if you buy a dreambox buy a 12v with 3 amps power supply, as this will not cause problems and keep your box running longer. But check before you buy a new one.
