My hdmi connection for dvd & cable have both stopped working. The receiver is flashing

I assume you have tried both hdmi cables from box to tv. If both works good.Cconnect to amp. Connect cable box also on other hdmi inputs like bd, dvd, etc to make sure the spesific port is not faulty. If still no picture try to lower hdmi video display on cable box. You amp may not be able to display the higher resolution.

Make sure that the DVD player is connected into the correct inputs on the receiver and that the receiver also has the correct input selected to play. If your TV also has component video inputs it is best to connect the player directly to the TV. Otherwise, make sure you have the TV connected to the receiver via component video out.

1. Connect cable to cable HD DVR box, connect video out of cable box to Sony receiver TV video in, connect audio L and R out of cable box to Sony receiver TV audio in and connect TV out of receiver to video in of Panasonic projector 2. Connect Audio and Video out of DVD player respectively to DVD in of receiver. Good Luck :)

Hi there
Check your DVD players' settings/manual to ensure the HDMI port is the default output port. Also confirm that both audio and video are enabled on that HDMI channel as it can be separated to be only video or only audio in a lot of cases.
Confirm you are at least getting video out from the DVD with a direct connection to your projector with the HDMI cable.
If video is making it to the projector direct from the DVD, you will need to confirm your amp is monitoring the HDMI input if there isn't a specific input selection for it. Connect your DVD to the amp and your amp to the projector and test again that you are still getting video AT LEAST. This will help narrow down which device is not playing the HDMI game if you still have issues at this point.
To sum up;
Confirm HDMI is the default output from the DVD for both audio and video.
Ensure you are getting video AT LEAST with a direct test to projector.
Confirm your amp is monitoring the HDMI input coming from the DVD.
Hope this helps.

It is a lose connection symptom when you wiggling the chord it will be fine it is a cold solder its needs to resolder the connection base so it become firm and works normal again.

Hope it may helps you;

It's the other way around.

Hook up the Cable box to the Amp; and the blu-ray to the amp, then connect amp to LCD.

you want to use the best available options for audio:
HDMI > Digital Optical > Digital Coax > standard RCA

And the similar for video:
HDMI > Component > SVideo > RCA cables

I would connect Blu-Ray via HDMI to Amp, and Cable box via HDMI to Amp. If your cable box does NOT support HDMI, but you have an HD package, ask your cable company for an upgraded box.

If you don't have one, the manual is available online: http://static.highspeedbackbone.net/pdf/AVR-488-OM-E_101.pdf

Suggestions:

1. Reset to default values. Per page 36 of manual: 1. Turn off Power. 2. Press Power while simultaneously pressing Speaker A and Speaker B. 3. Once the display starts flashing at intervals of about 1 second, release the two buttons.

2. Make sure you have AM or FM radio reception. This makes sure your speakers, amps, etc are connected and working correctly.

3. Connect DVD player to HDMI 1 in and TV to HDMI Monitor Out.
Play a known good DVD that works when you connected the DVD directly to the TV via HDMI.

Select the DVD/HDP input on the receiver and play the DVD. You should not have to perform any input assignments, etc. It should just work, as HDMI1 is the default system setting for DVD.

4. If possible, obtain a STB with HDMI out & repeat step 3 using the HDMI2 TV/CBL input. Keeping the signal path all digital (HDMI) will give you a better picture quality than forcing several analog to digital conversions (component video is analog).

4A. To use the component connection, first test by connecting the STB directly to the TV via component video/audio if possible. This tests that the component video output of the STB is working correctly.

Next, remove direct connection and connect via receiver. Connect STB to receiver as shown on page 13 in manual. Connect component video output from STB to component video input #2 (tv/cbl) on receiver. Connect the STB audio output to the corresponding tv/cbl audio inputs.

Make sure nothing is connected to the HDMI2 input or to any other TV/CBL inputs (composite video, s-video, digital coax audio).

Now select the TV/CBL input and turn on the STB. You should have both audio & video.

usually that is an issue of cabling and/or the monitor. The Marantz units are pretty darn stable. Check your setup to see if it is upconverting.

If you can, try a new HDMI cable to the TV. You could also try the second HDMI out, to see if there might be a problem with that particular output port. You can also try a different HDMI port on the TV.

Another thing to try is to directly connect your DVD player to the TV. If your cabling is all in walls, etc, you can get an HDMI coupler at a big box store for $15.00 or so. That will tell you if it is any of the cables, the DVD player, or the TV.

Are you using the HDMI for video AND audio or just video? Are you using the reciever as the video switcher by routing your devices into the amp and then from the out of the amp to the TV and then back to the amp from the TV HDMI output and the digital output? You may have a loop going on and the amp can't handle it.
If you are coming out of the TV with both HDMI and digital hooked to the same input selection on the amp and have the amp set for auto signal select, it could be throwing the amp for a loop and causing it to freak. From what I can see in the specs for that amp it has 2 HDMI in for connecting a HiDef Sat/Cable box, a DVD or Blu-Ray player or a gaming console, and then 1 output to the TV. HDMI handles both audio and video. Disconnect the digital cable and just use the HDMI for both audio and video.
The optimal set up would be as follows:

With a cable or sat box with HDMI out, go to the HDMI input to the TV. From the TV use either HDMI OR digital to the amp, not both. If you have Blu-Ray or HDMI DVD, connect that to the other HDMI input on the TV.

If the TV has only 1 HDMI input then connect the Cable or Sat box to one of the amp HDMI inputs and the Blu-Ray/DVD to the other and then from the HDMI out to the HDMI in to the TV with NO audio cable from the TV to the amp. Then use the cable remote to change channels.

See if one of those connection maps works for you.

If you need more help, let me know. Include the TV model and the digital audio cable interface type, whether it is optical or coax. It would also help knowing if you are using a Satellite or Cable box and which one it is.
