tutorial on freezing picture

[big dove]

just found this hope it helps someone

The following is a short tutorial for those with picture freezing problems, or faults with their tuners
Locking up and the DBox tuner



If your box locks up there are several possible causes.

Hardware i.e.

1. Tuner

2. Avia Chip (Graphics)

Software

3. UCodes

4. Older image (without Cydines new fixes)



If you press the RED button then the BLUE button with most images it will display (amongst other things) three readings, a lot of people misunderstand these and think the BER is the most important IT ISNT.

BER is Bit Error Rate and bellow 20,000 is better but NOT essential, i have seen perfectly good pictures with it above 50,000

Sig is Signal strength and of course the higher this is the better. I have seen perfectly good pictures with very very low Sig i.e. 30 and less, and amazingly many boxes work perfectly with a 0 Sig.

SNR is the most important (Signal to Noise ratio) this is how much of the AVAILABLE signal it can see above the noise, and that is why even with low Sig or poor BER if it can see enough signal above the noise it will work just fine. So this MUST be above 55,000, if it is less you will have freezing picture and jerky movement or even no picture at all. This reading is normally between 62,000 and 64,999.

And you may still get EPG but no picture with low SNR

If you cant get it above 55.000 check your cable feed, 1. with another box if poss 2. make sure there is no physical damage to the cable flattening or cuts, if there is change it try again.

If you havent had it working on this feed you may have an *attenuator in your wall box (see below). Remember just because your cable modem works does not mean your DBox will.
A splitter and an attenuator are different animals, a splitter will have NO db figures on it, an attenuator will, they can look the same and an attenuator can have 2 outs (looks like a splitter but its NOT) if it says somthing like 3db or -6db or the like it IS an ATTENUATOR, NOT a SPLITTER and should not be used as a splitter or you may get jerky or no picture

* Attenuators reduce your signal, i.e. 3db reduces it by half (50%), 6db reduces it by 3/4 (75%) 12db will only leave you 1/8 (12.5%) of your original signal. So as you can see if you have a 3db Attenuator removing it will double your signal !

Talking of freezing screens, I think I may have made a fatal mistake.

I tried out the "Blade.Fixed.2x" image and whenever I start the box it sticks on the image and I'm finding it impossible to get rid of this. I've tried rebooting it 4 or 5 times and also leaving it for an hour to chill out but that hasn't worked either.

Any ideas?

Oh I forgot to mention, I can't even ftp to the box either, I keep getting a timeout error. It seems impossible to actually get into the box at all
