Question about Aiwa AV-D57 Receiver

1 Answer

Cable Box compatibility.

I use a Scientific Atlanta "Explorer 3250HD" cable box supplied by Rogers Cable Systems for my home TV.
I decided to purchase my own cable box; and purchased an exact duplicate "Explorer 3250HD" cable box on-line.
It appears that the purchased box is for ComCast use; and Rogers Cable advises me that it will not work with their system, and offers/provides no modification service to assist me. 
It appears that "Explorer 3250HD"  does not mean interchangeable.
Who provides such a modification service?

HDMI signal cuts out for a few seconds constantly from receiver to television. It does it when switched to cable box and the roku box. Onkyo TX-SR606 Scientific Atlanta Cable box thru HDMI Roku Box...

Mine did the same thing where the screen would go black for a few seconds and then the picture and sound came back. I would try (1) switch HDMI cables, (2) try a different HDMI input in the back of the receiver, (3) try different input in the back of the TV. None of these seemed to work with mine. I finally ended up running the cable box direct to the TV and only run the audio through the reciever via coax or digital. No more problems. I think the HDMI inputs in the back of the reciever have a problem continuously carrying the signal if it is the leaset bit weak.

Picture/audio problems on my HDTV

This is a cable box problem. Could be a lack of signal stregnth or bad HDMI output.

The SA boxes have a very bad history of this, try using the component video output and see if the problem persists.

The HDMI is a real glass jaw of those boxes; but this problem could absolutly be your incoming signal...high def channels require more signal strength and that is what causes audio drops, pixilation and flicker.

If it was the HDMI in the receiver/tv you would get:

- Black screen, Pink fuzz or green streak dropouts.
- "Fireflies"
- Audio cutting in and out
- Not pixilation!

So what is my approach? If the box is rented or under warranty get it replaced. If the problem persists then call your cable company and arrange a service call at their expense.

If the box is not under warrenty go ahead and call the cable company and complain about a poor signal. If the signal is good, use the component video looks almost identical anyway.

Let me know if this helps,

How can i use the remote from my yamaha rx-v465 reveiver to control the scientific atlanta 8300hb cable box?

Yamaha remote has ability to control other devices (TV, DVD, cable box, ...) only by pre-defined set of models. Look up in your manual to the Yamaha where you will find list of manufacturers and models of devices with corresponding codes. If you can find your model there, program it into the remote. If not, you can try some of the other codes, at least program +/- and other simple functions should be quite compatible among brands.

I would like to hook up my components without having to turn on the receiver to watch tv from DVR or Cable if possible. I have Scientific Atlanta Explorer 8300 HD Cable DVR w/HDMI out, Samsung TV w/HDMI ,...

You should not lose any picture quality from the DVD player. I am currently having the similar setup with PS3 as the Blu-ray DVD player with HDMI and a Samsung DVD as regular player with component cable to a Samsung LCD TV. Remember the quality on Blu-ray is better than normal DVD so don't expect more than what it is.

Sony PCM 48 Issue

As long as you continue to have both HDMI and optical outputs connected at same time from the cable box, it will probably always choose the default as HDMI. If you do not want to change any connections then the best thing to do in this case is to always leave the cable box turned on. Otherwise, disconnect the HDMI and connect it to the TV by component video.

Picture sound blackout (blink) when cable box/receiver HDMI used

Onkyo service told me, the second timethat I called them, that there is a known HDMI handshake issue with Motorola and Atlanta Scientific cable boxes. The only solution, and it was a solution, is to connect the box through the HDMI 1 port ONLY. All the other (2,3,4) result in blinking/dropping of signal. I did this, changed the cable/satelilte setting to HDMI 1 and all is well.

I have the following hardware: Marantz SR-4003 Receiver, Samsung LN52A650 HD TV, Samsung BDP-1500 Blu-Ray player, Scientific Atlanta Explorer 8300HD cable box, two Paradigm Millenia 20 LCR Bookshelf...

Remove the HDMI cable (out) to the speakers from the receiver.
Connect regular speaker wire from the receiver to the speakers.
Of course, remove the (now extra) HDMI cable from the tv.
That will remove the loop.

Onkyo HT R510 is broadcasting all digital and 5.1 from the cable box as pcm

Chances are that Time Warner is just plain wrong. That's what you get with free tech supp....oh, uh right. scratch that.

Your receiver seems to be receiving a 2-channel digital audio signal (PCM) from the cable HD box. With this type of input signal, you can't select Dolby Digital on the receiver.

If you have a Scientific Atlanta 8300 (or a closely similar model):
Press [Settings] button on the remote twice. This will open the General Settings menu. Go to "Audio: Digital Out" and the select Dolby Digital (by hitting [-> Move Right]).

If you have another type of cable box, just review the settings menus until you find something relevant to digital audio out and avoid PCM, stereo or "down conversion", but look for Dolby Digital, DTS or "All".

Please keep in mind, that when connecting devices via HDMI cables, your box may decide it's smarter than you and reset the format of the digital audio back to PCM. This is some possibility of this occurring if the cable box or TV is unplugged and plugged back in.

If you have problems, add the cable box make and model and let me know.

Yamaha HTR 6040

I e-mailed Yamaha (Canada) about this problem and they said the only codes they know of are the codes that are in the owner's manual. But these codes just appear to be for the remote control that comes with the product and not for the cable remote.

So can someone out there come up with a solution?
