Question about Televison & Video

HDMI input issue with a Samsung 52 650 LCD, Yamaha 663 7.1 reciever HDMI issues, Scientific Atlanta Digital HD Cable Box I recently had to unplug my Samsung Reciever from my Samsung LCD and cable box. When I reconnected and rebooted everything, I was unable to make a connection via the HDMI cable. LCD only gets snow which itermittenly turns on and off, on and off; sometimes there is a picture instead of the snow, but its very red and just truns backto the on and off snow. TV does this as soon as I connect the LCD to the Reciever via HDMI only. When I connect the LCD via HDMI directly to my cable box and hook up the Reciever with analog cables, the system functions ok. I am assuming it is a setting or compatability option? Can someone help ?

    Only fixes are: disconnecting HDMI cable (SDTV signals restored immediately) or connecting HDTV via component jacks (no SD-composite blocking at any time).
    SD output via composite connectors should never be blocked if HDMI device is powered off.

    Use...DVI (Digital Video Interface) connectors, found on some graphics cards, are used for sending video signals digitally to screens with a suitable interface. They bypass the needless and potentially quality-reducing digital-analog conversion process. 
     
    The DVI interface, however, is soon to become obsolete, with the release of the HDMI interface.

Unplug everything from main, wait ten minutes, then plug devices back to power.

    This is not a settings problem, settings get reset if you unplug from power, the problem is probably because you unplugged or plugged back HDMI cable with the devices on.
    This can jam or damage the HDMI signal board (Input plate) on one of the devices.

    Just in case start checking settings, set resolution to same value on both TV and receiver.

    If that did not work, then reset settings by unplugging everything for ten or twenty minutes.

    If still no luck try a different HDMI port on tv, and even a different cable if you have one.

    If all the above did not fix it, then you have probably blown one of the capacitors on the HDMI signal board, and the component must be replaced.

    Nope components are those tiny things mounted on circuit boards inside electronic devices, like ICs, resistors, diodes , capaciors etc.

    My suggestion is quite simple:

    Do a general hard reset first, by unplugging both TV, DVD and receiver , waiting ten minutes and connecting everything back. This will drain power and reset devices.

    After startup, check display settings on both TV and cable receiver, set everything to 720 Dpi to start, this setting is supported by both devices.

    If still no luck , try a different HDMI input on TV.

    If still no joy, there is an internal fault either on TV or receiver, both must be tested with different devices using HDMI connections, in that case it is better calling the number listed on the owner manual.

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.

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.

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.

Want to add all of my video components to my rxv 663 reciever


The rx-v663 has 2 hdmi inputs, and 1 HDMI Outputs, The way I would run is 1 HDMI in dedicated to the Blu-ray, This will do the audio HD True digital, DTS-HD , then video out to the TV for HD 1080p resolution, On the cable box out do you have an HDMI 1.3? If so sport it to the other available receiver HDMI IN, net the same in/out as the blue ray, minus a 1080p result video which will only happen Blu-ray, cable will result 1080i HD and audio HD will vary with the signal broadcast format.

Intermittant disruption of Picture and Sound on View TV/HDMI only


If i am not mistaken you can select the HDMI signal going out on the 663, this means you should select to have only pictures to go out as sound will have to be reproduced by the 663.
So HDMI output setup on the 663 should indicate image only, no sound.

Off Air?


The Scientific Atlanta box was a cable box and recieved CATV signals. The Direct TV box is satellite only. You might check if it has a built in ATSC tuner for off air digital signals. Direct TV in most locations offers the major networks in HD format.
