Default Scientific Atlanta Explorer 8240HDC

I have my first HD cable box, Scientific Atlanta Explorer 8240HDC (from Time Warner).

I am looking for a manual. Doing a search here at High Def Forum, I found a link to a thread here that pointed to the manual, but the link in that thread to the manual is no longer valid. Does anyone have a current link?

I am also experiencing a problem, when I turn on the cable box, I sometimes find that a channel that I know is 1080i shows up on the cable box (and on the TV) as 480p. I have gone into the cable box several times by pressing the Info and Guide buttons on the box itself (not the remote) and made sure that 1080i is the only resolution selected. Does anyone have a solution that can stop 1080i channels from showing up as 480p?

Does the USB port on the front of the 8240HDC serve any purpose?

Thanks

Here is a link to the manual at the Scientific Atlanta site. Its the same manual for the SA 8300HD series.

http://www.cisco.com/web/consumer/su...s2/4003870.pdf

AFAIK with my Time Warner [Rio Grande Valley, Texas division] SA 8240HDC box if you use HDMI between the set top box and the TV then selecting the resolutions via the advanced configuration does not work. In fact there was a warning about this when I tried to setup the Advanced settings on my SA 8240HDC. That only works for component cables. Note this is different from my Cox SA 8240HDC box based on apparently slightly different firmware.

To get 1080i resolution you can go into settings (press the Settings button twice) and select Set: Picture Format for Upconvert 1 (you then get HD in 1080i and SD in 480p) or if the Set: Picture Format is set for Auto DVI/HDMI press the Settings button once and select Picture Format or Picture Size for all 1080i (HD and SD).

See this for details...

http://www.cisco.com/web/consumer/su...s2/4003114.pdf

Personally I don't know if the front panel USB connector is alive or not on Time Warner boxes.

So I downloaded the manual, and followed your instructions, but I am still having the problem that HDTV channels show up as 480p when I turn on the Cable Box. I have "Set Picture Format" set to "Fixed", and each time I turn on the box I have to go to Quick Setting->"Picture Format" and choose 1080i. Even when I do that, the HDTV light on the front of the cable box does not come on. (Does that matter at all?)

I also tried Upconvert-1, but contrary to the manual, a 720p channel shows up as 480p, and I am having the same problem when I turn on the computer.

I have also re-confirmed that only 1080i is chosen in the cable box setup (pressing Guide and Info on the box).

Any other suggestions?

I would try...

1. Power off the SA 8240HDC box by pulling the power cord, wait 30 seconds then power on and wait for the box to reboot, ie. the time appears on the front panel.

1b. Turn on the HDTV. Make sure the SA 8240HDC is off.

2. Go into the SA 8240HDC setup routine, ie. press [Info] + [Guide] buttons, and select option A, ie. the Easy setup, and select option B - Widescreen. See pages 9 - 11 of the Quick Start Guide.

3. Power on the SA 8240HDC.

4. Go into settings, ie. press [Settings] twice and configure Set: Picture Format to Fixed. See pages 14 -15 of the Quick Start Guide.

5. Exit the settings and tune to a known HD channel that broadcasts in 1080i, ie. the local CBS affiliate for example.

6. Press the Settings button once and scroll to Picture Format: [maybe marked Picture Size:] and select 1080i.

Test that you stay in 1080i by using the Channel buttons on the remote to change from channel to channel including the SD channels and that the TV displays everything in 1080i.

Thanks again, Sooner Al! This seems to work, when I turn the cable box off and on, it stays at 1080i.

One last issue ... the HDTV light on the front of the cable box doesn't light up when I turn the cable box on and it is set to a HD station. Does that make a difference or not? (If I change the channel a few times, then the HDTV light comes on and stays on)

The HDTV indicator on any of the SA set top boxes I have used is flakey at best IMHO. Sometimes its on and sometimes its off. Personally I don't worry about it as long as the picture is in HD...

Glad its working for you...

Recent history seems to indicate trouble in that area, ie. a bowl game win. By the way its Sooners with a capital S...

Hi,

I’ve got an SA 8240 HDC running SARA 1.90.5.113 on Cox Cable in Green Valley, AZ. I connected the 1 TB WeaKnees drive with no problems. The problem I’m having is that I get random and frequent breakups/pixelation and audio drops, as many as 28 every hour. These breakups last about a second and sometimes come in clusters of 2 or 3.

My voltage when tested varied about .8 v from 120.2 to 121v. The TV and internal drive worked fine before connecting this drive.

Do you have any suggestions as to how I can make this thing work? Thanks for your help.

Gail

Default Statistics Page

One time I was messing with the buttons on the remote trying to fix a PIP problem. Somehow I got to some kind of technical stat page the showed what I thought was the signal strength and some other data. Does anyone know how to get to this page? I can't figure out how I got to it. I'd like to see my signal strength and I think this page showed that.

The following steps can be down with or without the SA 8240 power on.

1. Hold down the select button until the Message light blinks
2. While the Message light is blinking hold down the Guide and Info buttons at the same time.

This will bring up the Status Summary page you can move through the different pages with the Page Up or Page Down on your remote, or Vol + as Page Up and Vol - as Page Down on the front panel.

Pressing Select on the Front Panel darkens the screen, the same goes for B button on the remote.
Pressing A while in the Status Summary will tell you what the different font colors mean, same as a Legend on a Map. If you happen to press the A button a second time you will exit from the Status Summary page.

This DVR is junk. There should be a fixed message at the top of this thread that says: "Before posting an issue here, unplug and replug the box, then wait 10 minutes for the reboot. Your problem will then likely be fixed."

I've had this box for 4 months and need to reboot it a few times per week.

1. Guide freezes. Reboot DVR. Fixed.
2. Guide and other remote functions slow to a crawl with multi-second response times. Reboot DVR. Fixed.
3. Horizontal lines and shadows on multiple channels. Power off and power on. If that doesn't fix it, rebooting the DVR then powering it off and on with DVR power switch ought to do it.
4. Breakups and drops...you know the drill by now.

I will say it is somewhat convenient that all of these signal delivery problems are solvable with a reboot of the DVR. It gets you around debunking that your problems are user errors, which the so-called experts say are the cause of 90% of signal delivery problems.

Reboot fixes indicate "Step 1: Replace DVR".

I'm fed up with this piece of junk. I'll be calling TWC on Tuesday for a replacement. I suggest everyone do the same. Even if the new box is no better than the old, it will bump up their failure stats and maybe they'll get after Cisco to dejunkify this crap. Why should we have to go to forums to investigate workarounds and remedies? The providers of these cheap crappy pieces of electronics should be aware that all their customers want is to be able to WATCH TV, not become electronics troubleshooters. That is a reasonable expectation.

If I can't get a new box out of TWC, they should at least supply me with a cord with a kill switch that can run under my rug over to my easy chair.
