Connect Pi4 to TV Hitachi (mid 2000's) HDMI

Question

trying to connect Pi4 to a Hitachi TV (pretty old - mid 2000's), however it has the HDMI port. So my Pi4 is connected.

SD card is with OS's on it.

Any idea why Pi4 is not booting up? I have selected a PC channel on TV.

Thank you.

Which OS how did you flash it? Suggest flashing Raspbian Buster with Desktop direct to sd card with Etcher. You may then need to force your TV resolution in /boot/config.txt. — CoderMike, May 1, 2020 at 11:55
Thanks, not sure what you mean by flashing Raspbian Buster. In regards to forcing resolution, there is no config file in OS's folders. I reformatted the Sd card and uploaded NOOBS to it via copy/paste from the RP website download. i.postimg.cc/qM3CMc0R/Screenshot-2020-05-01-at-13-02-29.png — Linards Berzins, May 1, 2020 at 12:04
Maybe the Raspberry Pi imager would be easier raspberrypi.org/downloads — CoderMike, May 1, 2020 at 12:39
Thanks, will I be able to install the rest of the OS's after? — Linards Berzins, May 2, 2020 at 10:46
I installed Imager, still the same, no connection made. Will have to email Pi org. Thanks — Linards Berzins, May 3, 2020 at 18:25

Try the following in /boot/config.txt:

# force HDMI
hdmi_force_hotplug=1
# disable EDID
hdmi_ignore_edid=0xa5000080
# DMT group
hdmi_group=2
# 1366x768 60Hz 16:9
hdmi_mode=81

Thank you @CoderMike. Still no luck with these settings. Tried other ones too. Tried as well github.com/raspberrypi/rpi-eeprom/releases/tag/… It looks likeit could be the issuewith the Pi itself, as I do not even get any flashing green LED light when trying to boot up. Thank you for the effort on help.

What power supply are you using? Do you see a constant red led?

What size sd card are you using? Maybe try using Etcher to flash as it verifies? balena.io/etcher I'm out of ideas, this is the official won't boot thread raspberrypi.org/forums/viewtopic.php?f=28&t=58151

This mentions your odd resolution not working on a Pi4, might be worth you commenting on the post raspberrypi.org/forums/viewtopic.php?f=28&t=266797
