This is weird as the Power on/off signal is only sent by the remote and should have nothing to do with the 6412 and its internal programming... Perhaps a coincidence?

pdubois thanks for taking the time to think about this problem of mine.

Nowhere in our dialog have I mentioned that I also had to go into setup and change the AC Outlet from switched to unswitched in order to stop the TV from coming on at night. Maybe I am doing too many things and one is countermanding the other. What setting do you have for your AC Outlet?

All this is assuming that you are able to turn both your TV and 6412 off together with the remote power switch and not have your TV come on when you record something at night.

I guess what I am asking is - is this just my problem or has anyone else noticed the same phenomena?

Further to my problem with the TV coming on when a recording starts.

The Atlas remote is programmed, using the master power key, to turn both the DCT6412 and TV on with the remote PWR button

The TV is plugged into a separate outlet not into the DCT6412.

In the DVR setup the AC outlet is set at unswitched (it doesn't seem to make any difference switched or unswitched).

The TV picture still comes on (not the sound) when a recording starts.

Is this an inherent problem or due to something I have set up incorrectly?

Hi, if you power up your tv while a recording has already started from the box being previously off there will be no sound. That is normal. There is a fix I think that Technut posted re: unmuting the sound by modifying a button on the remote to do this, similar to adding the 30 second skip. You will have to enter some kind of code etc.

Re: powering up your tv and dct at the same time if a recording is set at night, I have not noticed this. I haven't messed with the unswitched switched option in the dct and my dct and tv are plugged in to a power bar rather than plugging the tv into the outlet on the dct. With that setup only the box seems to go on and off on it's own when needed for me anyways. I have set up recordings late at night and the tv is unaffected even if I've been around to see the box fire up and shut down.

That is strange how your tv also fires up even though your not in the outlet on the dct. Perhaps set your remote back to default and then add the tv to it again. Worth a shot.

Yes I saw this and programed my remote to unmute the 6412 it was a good tip!

I have set up recordings late at night and the tv is unaffected even if I've been around to see the box fire up and shut down.
So at least I know there is a solution and that it is not necessary for the TV to be on during a recording.

Perhaps set your remote back to default and then add the tv to it again. Worth a shot.
I will give this a try - thanks for the advice

This didn't work but I discovered that if I turned the DCT6412 and TV off with the remote PWR button and then pushed the power button on the TV (seemingly had no effect on TV) the TV doesn't come on when the recording starts! Then I have to reverse the process - press TV power button (nothing seems to change on TV) press remote power to get both functioning again.

I'm guessing this problem has more to do with my TV than the DCT6412.

Sounds to me like your TV isn't powering down from the remote. Goes black because there's no signal, but is actually on. DCT comes on to record in the night, and there's the picture!

Your solution (hitting the power button on the set) is maybe turning the TV off for real and on for real.

Try this: after you push PWR to turn the DCT and TV off, hit the Menu button or whatever on the TV. If your TV menu comes up, that means it's not turning off from the remote.

Did you post your type of TV? Maybe somebody with a similar set could help you out. I know there are TVs that go into Standby, and come on auto when they detect a signal; maybe hitting the button on the TV toggles it from standby to off and back?

I have set my 6412 outlet set to 'Switched' but there in nothing plugged in it at this time. No, the TV does not come on when the recording starts and both the TV and 6412 have been switched off by the remote power switch, holding it 2 seconds. I can hear the relay clicking in the 6412 when it goes off and then I hear the relay clicking in the TV set when it powers down as well. It seems to me that your TV is not really switching off, just blanking off... This what I accidentally did once when I did not hold the power button for the full 2 seconds.

I have noticed the problem with the 6412 being muted when a recording has already started. I am going to do a search for the fix on this board. [Edit: OK got it, thanks Technut! This fix works as a toggle for the 6412 MUTE (and not only to de-mute when recording) so it is possible to reprogram the MUTE button on the remote to control muting at the 6412 level rather than the TV level, useful if you use external amplification]!

My TV is a 4 year old analog set. It is a Sony 27" FD Trinitron wega KV27FS12. I am sure this is my problem.

I bought the 6412 in anticipation of moving up to HDTV. I am very happy with the programming capability and the analog picture is unchanged i. e. good. It is so good that I am in no hurray to jump to a HDTV ready set. The HD programming seems poor at this point.

The HD programming seems poor at this point.I have had HDTV only for a few days but I must say that the image quality is way better than the best picture I had before. My wife did put it very simply: "it seems like I had been watching TV until now without my glasses on" and she is hard to impress as far as technology goes!

I totally agree that there is an obvious lack of HD channels available (at least in Vancouver, BC). I really like PBSHD but they keep repeating the same shows over and over... I am really hoping that the Discovery Channel will be on HD soon and many more!

Hi Ian,
Don't forget that you can watch the HD channels via svideo or component video on your analogue tv, and get dvd-quality picture and 5-channel sound (much cleaner signal than the equivalent SD channel).

Hi Shaggy,

My 6412 was set up by a Shaw technician. When I look at the HD channels they seem to be a bit sharper than the analog channels but I can't really tell. I'm not really sure what svideo or component video is. Is there a way to tell if the technician installed one or other of these? I have Home Theatre in a Box so the improved sound would be a bonus.

What is important is that I very seldom watch NBC, CBS or ABC. Now if they put BBC Canada on to HD I would probably buy a new TV tomorrow.

I bought my 6208 about 6 weeks before I bought a Hi-Def TV. I had a 5 1/2 year old 36" Wega SD TV. There was a VERY significant difference in quality that I could see on the HD channels compared to SD channels. The difference was pretty much the same as DVD was to regular TV. I was using S-video at the time. Now, of course, with an HD TV the difference is again much much more.

Hi Ian,
I downloaded the manual for your TV from sony support. Your tv does support component inputs on Video 4. Your 6412 should have come with a component video cable (the three coloured cable). Use that to connect to the Y Pb Pr inputs on the back of your tv on video 4 and the same on the back of the 6412. Then hit the tv/video button till you get to the video 4 input. You may notice that the HD channels are clearer and have better colour (I do with my tv). Results my vary for you.

Note that you'll have to set up your 6412 to output 480i on component outputs. There's instructions for doing that in other posts - just search for my previous posts in other threads.

For the audio, just go from the optical output of the 6412 to your receiver (or use the PCM output if your receiver doesn't support optical). This will give you the 5-channel sound for the HD channels that broadcast on HD.

One note is that on my tv I use the S-Video connection (round multi-pin connector) for SD signals, and the component for HD, as that gives me the best picture quality. I then hit the tv/video everytime if I switch between HD and SD (which is a bit of a pain).

The last two nights my 6412 has locked up at 4:20am and 4:25am respectively.

I leave it on overnight but I don't have any activities scheduled for it at that time. I can tell when it locks up because I have the LED display set to show the current time, and it freezes at that time. It still outputs video and sound from the channel it is on, but it is totally unresponsive to the remote or front panel controls and I have to pull the power to get it working again.

I don't have any new code, so that's not it. But I'm just wondering if it was coincidence or something from the head end... anyone else seen this in the last couple of nights? I'm in Victoria.

Ambient -

You joined in May 2003 and you've only ever had one post - the above one?

I'm overwelmed by the amount of support found in this forum. Shaggy thanks for the effort. This is what the Shaw technician has hooked up. I now remember finding the component video cable for him. I am now convinced that the HD channels are coming in better than the analog channels.

Note that you'll have to set up your 6412 to output 480i on component outputs. There's instructions for doing that in other posts - just search for my previous posts in other threads.

Yes I have set my 6412 for 480i from previous suggestions in this forum possibly they were yours.

For the audio, just go from the optical output of the 6412 to your receiver (or use the PCM output if your receiver doesn't support optical). This will give you the 5-channel sound for the HD channels that broadcast on HD.

OK I will give this a try.

I think I understand this but it looks like a lot of trouble. I'll save this exercise for a rainy afternoon.

Thanks for the suggestions Shaggy

-component video is 3 wires much like the composite but usually better insultated (red,green,blue) upto 1080 lines of resolution(analog video)

This is what the Shaw technician installed for me. The component cables came with my 4 year old TV.

Now if your tv does not have component it might be time to upgrade! depending on size i would not buy a tv over 30 inch with out having component and DVI , this ensures more of a future proofing.

Did this help at all?

AMBIENT this has been a great help. Thanks for the advice. This is a learning experience that is for sure!

...-DVI digital video interface- the best to date for video , the cable is retangular in shape, this has the same resolution as component how ever the signal stays totally digital unitll it gets to the tv.(ther are newer dvi connections called hdmi this it just content protection enabled dvi...
I don't think that's quite correct. Both DVI and HDMI can play the content protection game. The big difference between DVI and HDMI is that DVI carries only the picture, while HDMI carries the picture and sound. Picture quality for DVI and HDMI is identical.
