Intermittent short term drop of video or total lack of video.

During movie playback (usually) at 1080p, and (3D models) if the video is present with the menu up, but not in bypass, this can be an indication that the data received

by the panel projector is on the edge of usability – try substituting the output cable if this is the longest run – if not try the input cable.

Also confirm the cable is capable of carrying high speed signals. In some older installations where existing cables are used to carry 1080i/720p signals these cables

may need to be replaced with high speed cables capable of 1080p/24 operation or in the case of 3D certified High Speed cables.

Remember HDMI cables become an integral part of the whole system not only sending video/audio signals but the all important HDCP protocol data.

HDMI video output setup (very important)

The default video output resolution setting is preferred. Many displays still request 1080i as their preferred resolution. If this is the case, a 1080p 24fps source will

result in no video. To correct this, change the output resolution from preferred to 1080p.

The default output frame rate is auto, which will only output frame rates the display indicates it is capable of in its EDID. Some displays do not indicate they can

handle 24fps signals in their EDID. If this is the case, then changing the output resolution to follow input will force a 24fps for such a source.

Video Source Setup

Correct setting of the video source will speed up video switching. Prior to v2.3, the default was auto, manually setting this to the input type used (HDMI, component,

S-video, composite) will greatly speed up video switching time. NB This is configurable for each source. (Auto setting removed from V2.3 onwards must be set per

source)

Green line on the side of the screen

In several cases, this has been shown in several cases to be due to the EDID information from the display requesting an incorrect sync polarity which shifts the image.

Types of displays showing this should be reported to the manufacturer and Arcam. This may be overcome on most panels/projectors by selecting the Overscan option

(screen zoom between 2 and 5%) on some Sony panels this is assigned per input.

Flicker on-screen or screen goes blank when selecting to play a Blu-ray from the navigation menu

This is due to the display device relocking to a different frame rate usually a transition from 1080p 60 to 1080p 24 – this is perfectly normal and an action of the panel/

projector relocking to the new frame rate.

Unable to set the source blu-ray player to 24fps

In some circumstance certain brands of blu-ray player may show the 24fps setting option as grayed out or unelectable this may be caused by the player not re-reading

the EDID back from the display device – in this instance you should.

Physically disconnect the HDMI cable and then reinsert at the Blu-ray players output.

Connect the player directly to the panel just for calibration of the 24fps setting.

Display in standby issues

Our automatic priority output switching system relies on correct implementation of the hotplug i.e the hotplug is used to indicate activity and should be low when the

panel is in standby. Some panels/projectors keep the hotplug high in standby causing us to believe that the device is still active hence not switching between output 1

to 2 or vice versa.

From revision of software (v2.0) IR codes are available for forcing HDMI1 (RC5 16-73), 2 (RC5 16-74), 1&2 (RC5 16-75) output modes for installers.

HDCP

HDCP authentication occurs every 2 seconds when protected content is played. In the event of HDCP failure the display will show a message generated by the

AVR600. HDCP authentication requires the entire system to authenticate and a failure is difficult to pin down to any one item in the chain.

Viera Link

It would appear that many Panasonic source devices such as Bluray/set top products have as default Viera link set to on – this may cause the player to ignore your

specified output resolution after a standby cycle i.e you have adjusted the output resolution and moved from auto to 1080p after standby cycle the player has reverted

to 1080i or another resolution – ensure that Viera link is switched off to cure this issue.

Switching of 3D video source material

If installing a 3D capable version of the AVR600/AV888 you must set the product to Video BYPASS. This option is found within the Video Output Resolution

settings. Please note video Bypass is only available on Output 1.

Changing Video output resolution from remote

Simply press the AMP button on the remote follow by Shift then within 1 sec press the Right arrow – you will see the current resolution display –press Shift and the

Right arrow again and the AVR will move to the next resolution.

Bypass of HDMI in standby

HDMI bypass when the unit is in standby (3D models) is not possible due to the HDMI PCB being powered down to save power.

Video drop out when going into and out of menu when using Bypass (3D only)

When changing between menu and normal video when using the bypass input, the HDMI chain needs to reconfigure. This can take some time (depending mainly

on the display). During this time the display is often completely blank and is normal.
