Recently I bought a Samsung Qled 55" Q60d and I found the OS very different of the LG that I used to have.
Anyway, I have a Raspberry PI connected on HDMI, and for some unknown reason it got corrupted. But I didn't realize when or if it really got corrupted. I just follow the indications that do not boot up, no signal on TV, etc.
I know it can happen from time to time, but the lack of information is killing me. I can't see the RPI booting up because the TV does not let me choose the HDMI that it is connected. I was selecting the input PC, although it is not a PC, and it can't let me change that either.
So, I need a way to select the HDMI that my "PC" is connected even without HDMI signal on that source. How can I do that?
It's weird that I cannot select whatever I want on the TV. Is my TV!!!
your Raspberry Pi isn't displaying on your Samsung TV via HDMI, the issue could be due to a faulty HDMI cable, incorrect TV input selection, incompatible resolution settings on the Pi, a problem with the HDMI port on the TV, or a configuration issue within the Raspberry Pi's "config.txt" file - check the cable connection, verify the TV input source, adjust the resolution settings on the Pi, and potentially modify the "config.txt" file to troubleshoot further.
Key steps to check:
Check the HDMI cable and connections:
Ensure the HDMI cable is securely plugged into both the Raspberry Pi and the TV.
Try using a different HDMI cable to see if the problem persists.
Check if the TV's HDMI port is functioning correctly by trying another device.
Verify TV input settings:
On your TV remote, navigate to the input selection and choose the correct HDMI port that the Raspberry Pi is connected to.
Adjust Raspberry Pi resolution settings:
Access the Raspberry Pi's configuration file ("config.txt") by editing it via SSH.
Modify the "hdmi_mode" setting to match your TV's resolution.
You may need to experiment with different resolutions to find one that works best.
Check for potential "config.txt" issues:
Ensure "hdmi_safe=1" is commented out in the "config.txt" file if you are experiencing color issues.
Consider adding lines like "hdmi_force_hotplug=1" or "config_hdmi_boost=X" (where X is a value depending on your TV) to enhance signal strength.
Restart the Raspberry Pi:
After making changes to the "config.txt" file, always reboot the Raspberry Pi for the settings to take effect.
Other potential issues:
Power supply: Ensure the Raspberry Pi is receiving adequate power from a suitable power adapter.
SD card issues: If the SD card is corrupted, it may prevent the Raspberry Pi from booting properly. Consider re-flashing the SD card with the latest Raspberry Pi OS.
Outdated firmware: Check for updates on your Raspberry Pi and TV firmware.
"On your TV remote, navigate to the input selection and choose the correct HDMI port that the Raspberry Pi is connected to. "
That's the problem, there is no way to select a specific HDMI port. I can just select "videogame" or "PC". And the latter is not appearing anymore because it isn't detecting. And I need to see what's going on the RPI to troubleshoot.
My initial question was that, How to select a specific HDMI port. It will solve everything. The TV is less than 6 months old so if is a HDMI port error, the HDMI cable is new too, and I just flash the RPI system so everything is brand new.
