Sony and comcast HDMI Problem

unforgiven · 10-09-2006, 03:17 PM

Sounds similar to a problem I once encountered where the TV would act up when switching between wide screen images and 4x3. Try this for giggles. On the 3412 for the 4x3 setup, configure it to send it wide screen. I forgot what the setting is exactly, but it's one of the choice along with 480i, 480p, ect. The 16x9 setting should be 1080i. Hook up your HDMI cable again and see if you still have the problem. With this setup, everything should be widescreen. Not a solution to your problem, but it will tell you if your TV is having problems switching between the two.

I will try it when I get home from work and let you know what happens

All these boxes have an output mode. find that and it will solve your problem . The Sony is basically adjusting the display to the output that is coming from the box.
As unforgiven suggestted and what I am trying to say is. once you have found your boxes output mode make sure it is only on 1080i. It you select multiple outputs then your sony is figuring out you output which casuse the delay/ blank screen.

So is that why when I switch to an SD channel is says something like 480i and then on the HD channels it says 1080i?

I changed the setting on the cable box to 1080i and it works fine now. thanks for all your help

nuttyinnyc · 10-11-2006, 05:29 PM

yes with these Sonys if you don't set it to one output on the box it sets it for you just like you saw if you watch SD it will say on screen 480i or 480p and the HD channels will say 720p or 1080i.
Now, I see you have it right. Every channel says 1080i and no more switch delay. Congrats now you can enjoy this TV.

I have the same sony model and comcast dvr box model. I have the same problem and the "workaround" of always outputting a 1080 signal for the cable box works for me too; since this avoids the issue of converting between signal types. The problem with the workaround is the tv features of the 480 signal are lost. You can no longer use the stretch mode to make the picture take up the whole screen. Anyway, I had sony and comcast techs come to attempt to fix the issue. They both acknowledged the issue but neither had a solution. The comcast tech escalated the issue and the last I heard, their labs were working with sony. I'm hoping for a firmware upgrade from either sony or motorola as a result, but I have not heard anything yet.

I have a Sony KDLV40XBR1 and have the cable box set to always send 1080i so that I don't have the delay when switching between HD and SD. Thus when I press the Display button on the Sony remote, it always says the input is 1080i. But the Wide button still works so I can set any channel (HD or SD) to Full, Zoom, or Wide Zoom. Are you sure the Wide mode doesn't work?

When I attempt to use that button on the remote, I get a message saying "feature is not available for current signal." I agree the delay between switching between HD and SD can be annoying and having the cable box do the upconversion is a good solution to the annoyance. However, I believe there is circuitry on the sony tv (especially the XBR model), that cleans the SD signal to make it look better. This circuitry would not be used if the cable box always outputs 1080i. The delay when switching between HD and SD is the tv switching circuit boards, so when it is always 1080 into the tv regardless of the original signal type, the analog circuitry that does this will never be used.

Try not to let the cable box do the signal converting. I know a lot of people dislike the delay in viewing a channel but by selecting only 1080i you are might not be getting the best pq possible as DMB said.

DMB: Do you have a option on your TV have a option section for 4x3 channels and 16x9 channels? The XBR's do but I don't know if your TV has it. If you do they should both be set to "full" which will solve your 4x3 problem. There are just some shows that will not stretch and if the do it looks really bad anyway. Also if you want, set the cable box to 16x9 and set 4x3 to stretch not wide or any other selection.

"the analog circuitry that does this will never be used." Remember these TV's are digital. Analog has nothing to do with the digital cable use. The only time Analog comes into the equation is when you use Componenet cables. then your STB converts the signal to analog then the TV converts it back to a digtal signal.
All signals received by this TV is converted to digital for display.

HDMI, DVI and Component ALL transmit true digital signals. HDMI and DVI can send higher bandwidth signals, but no cable provider can push them!

Sorry Scott, but component does not transfer a true digital signal, like it's HDMI counter part. It down converts the signal to analog during transfer and the TV upgrades the signal to digital. But it is still one of the best connection available today. The debate rages on on which gives you a better PQ, but I favor the HDMI. Why wouldn't I use the best connection available today if it is working?

excerpt of the definition of component cables:
Like composite and S-Video, component video is an analog interface, but its three cables better preserve the various elements of the video source signal. These elements are the Y signal, which carries brightness or contrast values, and the C signal, which carries red and blue or color data. Green values are parsed by a deductive process from reading all three streams. Therefore, component video is sometimes referred to as "RGB" for red, green, blue. The component video interface is marked either Y Pr Pb or Y Cr Cb.

Excerpt of the definition of HDMI:
HDMI much more desirable than its predecessors, component video, S-Video and composite video. HDMI is an uncompressed, all-digital signal, while the aforementioned interfaces are all analog. With an analog interface, a clean digital source is translated into less precise analog, sent to the television, then converted back to a digital signal to display on screen. At each translation, the digital signal loses integrity, resulting in some distortion of picture quality. HDMI preserves the source signal, eliminating analog conversion to deliver the sharpest, richest picture possible.

I have the same problem with HDMI and the Verizon DVR. When going through the Sony receiver the DVR will eventually lock up
