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.

  • 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 May 1, 2020 at 12:04

    Maybe the Raspberry Pi imager would be easier raspberrypi.org/downloads

  • Thanks, will I be able to install the rest of the OS's after? May 2, 2020 at 10:46
  • I installed Imager, still the same, no connection made. Will have to email Pi org. Thanks 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
