Begging for HELP!

Wed Feb 13, 2013 7:57 am

When using HDMI, my picture is color distorted. Its flashes red and blue and shakes.

Any ideas on what i could do?

The following are changes i have already made to my config file;

hdmi_safe=1
disable_overscan=1

hdmi_group=1
hdmi_mode=16
config_hdmi_boost=4
sdtv_mode=0
aspect ratio
sdtv_aspect=3

Here is what it looks like

THANKS!

I would go with a bad cable there are no color settings in the config files that I am aware of. Do you have any other device that has used the HDMI cable and same connection on the monitor?

Last place would be possible bad HDMI connection on the Pi itself. Is anything else plugged into it and what version of Pi 512MB?

P.S. The flashing improved when updating to : config_hdmi_boost=4

but still red tint. Looks normal when using Composite cable

One thing i noticed, when running the comand (tvservice -s) to show my current setting, it says:
[DVI RGB full 4:3], 640x480 @ 60hz, progressive

all attempts to change this to say hdmi or a higher resolution have failed

might this be why it looks so bad?

Try without the "hdmi_safe=1". I think this setting overrides many of the others, like hdmi_mode, so you only get a basic 640x480 screen.

So interesting thing happened in doing so... Right away i could tell the 16:9 kicked in, the flashing seems to have stopped, but still red all over.

When running the tvservice -s it now shows 16:9 but still as a dvi connection.

This is unclear - have you actually tried 2 different HDMI cables?
Have you tried a different screen?

Looks like you are missing the blue HDMI signal, this is almost certainly a cable / connector issue and not RPI hardware related.

I have also seen similar things with a bad connector.

Try values of config_hdmi_boost greater than 4. You can go up to 7.

I have attempted going up to 7

I have attempted 2 working HDMI cables on 2 working HDMI inputs

have not been able to attempt on another screen

I am starting to think the HDMI port on the RPI might be the issue

any other ideas?

No I'd say its the port either on your monitor or the Rpi and as you eliminated the monitor end with your cable box it looks like you have a wonky RPi ;)

Where are you? Someone may be able tocome round with an alternate Pi to try.

Thank you all for your help. It was in fact the HDMI port on the Pi. I had the Pi replaced and vuala beautiful picture.

But...

As always with our wonderful technology, fix one problem to encounter another.

In all my attempts to get XBMC installed/activated or whatever is required on Wheezy have resulted in utter failure. Finally found a step by step that seems reliable but sure enough, i get an error saying my 8gb card has run out of space during the installation of the libraries/dependencies.

Any recommendations on how to get XBMC with the least amount of trouble would be greatly appreciated.

Thank you all again

It is always going to be better to start a new thread with the problem as the subject.

For no other reason that threads with zero responses get hits. ;)
