Picture Freezing - Can someone advise on SNR Levels
 

Just looking for a bit of engineering info.....( t'engineer are you around ??)

On our Samsung box the picture occassionally freezes. When I go into User Info via PgUp - PgDown - Blue, we get a SNR of 41.2db and Return Power of 40dbnv;

Going into the mini event log - there is a few errors - these are Post RS / No Signal but both have the number 442750.

Can anybody help ????

TIA....

Is t'engineer actually a CATV engineer ?

I'm sure someone with the necessary knowledge will pop along.

No, he isn't. He works in the aerospace industry.

Those values you see on the page up page down blue pop-up are for the MCNS downstream and upstream, and only give you the box's own view of the connection. The TV picture will be unaffected by these values, being on a separate frequency, there's a separate SNR value. You can see it on the blue screens, but I can't remember off the top of my head how to get into these on a Samsung. I do have remote blue screens available that I can check if you want - PM me your STB MAC or smartcard number.

442750 (kHz) is a TV frequency - the Post-RS errors on this frequency will correspond with your picture freezing. Probably a signal level problem. You'll need to call ntl.

Thank you for the introduction BBK .

Someone told me they thought the freezing was sorted out on the Samsung:angel: .

Could it be the streams local to the street cabinet are not at the correct value BBK, causing something similar to the very early pixellation we had in the NW when you was an adopted mancunium.:cool:

Datastreams SNR and return power probs.

BTW Glad i am appreciated even though i do not work for NTL.:D
