Weekly Build PI4 4.5.10 - TV will keep blanking out, flashing or not working at all.

e4rthdog

I installed weekly build 4.5.10.

I made the installation and initial setup in a DELL monitor and everything was fine. I then moved my PI to my Philips TV model 55PUS7304

I am struggling for 2 days now to make it work. the behavior is one of the following:

Screen is blank and message no HDMI output is on
Screen is blanking every now and then (every 2-3 seconds)

I tried many config.txt edits using hdmi_safe or specific modes with no result.

On one of my tries i commented the dtoverlay line and the system booted up but there was no GUI, it just stayed at the command prompt of pi user.

Find below the output of tvservice -d edid.dat; /opt/vc/bin/edidparser edid.dat command:

I dont know if this is the builds issue or something general to my PI4 and the TV. Any help about what steps to follow to try to find out the cause?

Looks more like a bad cable than a software error/problem.

And this could affect only the TV?

Tried every resolution and also disabled enhanced settings of the TV for the HDMI port...

P.S. I have tested 2 official cables and it does the same....

Hm, then it's not a cable issue. Try adding to the config.txt file:

hdmi_pixel_freq_limit=200000000

and see if this improves the connection ?

So, i did it.

First boot was normal. I was able to see the logo , the progress of loading and the final screen. No blinks.
After shutting it down it booted with Blinking. TV was coming off and on every 2-3 seconds. Finally booted up. Another thing i noticed is that SSH was slow and one time unresponsive.Putty threw "Connection time out".
Another reboot and SSH seems normal now

Things changed with this setting but still unreliable.. What does it do?

It just filters out the 4k video modes. Do you have any other peripherals connected ? Have you tried another HDMI port of your TV ?

A logitech F310 and a wireless keyboard Logitech K400. I tried with other ports.

I have another PI4 with Libreelec which runs normal, tested in that port also , same behavior.

It must be something with TV compatibility cause Libre elec once did that blinking and i just put it in defaults 1080p and run smooth without any problem.

That would have been useful to mention in the first post. Try to force 1080p in your config.txt as the default resolution.

I have done it so using hdmi_group=1 and hdmi_mode=16 which has no effect....

I am downloading now on a separate card a fresh rasbian to test it directly on the TV for initial setup to see what happens....

That's a good test, though the RetroPie image is basically a Raspbian Lite image with added software, so I wouldn't be surprised if the result would be the same.

But hdmi_group shouldn't be 1 instead of 0 if you want to force 1080p ? hdmi_group=16 is not valid otherwise - see https://www.raspberrypi.org/documentation/configuration/config-txt/video.md.

Just booted up in fresh rasbian and it does the same. See the vid.

I guess i will have to move to raspberry forums...
