TV, HDMI, config.txt and other matters

Tue Apr 28, 2020 8:20 pm

Hi.

Just bough a Rasp 4.
Get all exited to show my kids.
Assembled the case, put the card in, connect the HDMI from my TV with an HDMI-to-mimiHDMI adapter to the Rasp, power in and... nothing happen.
So googled it. Easy. Edit the config.txt file in window and force the HDMI to get more power: easy!? Wait...
Got my window laptop, insert the SD: format not recognized.
SO googled it: it may happen (?).
Tried on Mac, cannot see the SD partition.
Tried on Googlechrome Linux: cannot access SD cards, yet.
So came into this forum: no one seems to have my problem.
Ah, I got a monitor also, but it has only DisplayPort.
:evil:
Now: what shall I do?
Can I access the config.txt somehow? Any other way I can try?
Shall I buy an cable HDMI-DisplayPort?
There is an issue using the adapters?

Few months ago a bought the same for my nephew and got it connected to a monitor in a blink..
I guess here my issue is with the TV and accessing the Rasp the first time to install the OS and get my config done..
Any help is more the welcomed!

Thanks and Regards,

Gabriele

Was the uSDHC card provided with the Pi (as a kit) and, possibly, pre-installed with the NOOBS installer? micro-HDMI-to-HDMI adapters have given problems for some users. Personally I've found the Amazon "basics" line of micro-HDMI-to-HDMI cables to work well and, of-course there's the official ones too. Since the present "status" of the supplied uSDHC card is now "in question" perhaps, given you have access to both a Windows or Mac m/c it's worth re-writing it with the Raspbian + Desktop only (default) image via the new Imaging tool: https://www.raspberrypi.org/blog/raspbe ... g-utility/ ?
(download here: https://www.raspberrypi.org/downloads/ )
Trev.
Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, 2xB2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, and a A+) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm

Thanks,

yes, I bought the SD from Pi-hut with the NOOBS in it together the the Rasp, the case etc.
The adapter micro-HDMI to HDMI was bought in Amazon ma it was not the Amazon-basic one.
Before trying re-installing, I just ordered a micro-HDMI to VGA so I can see if I can see the video output on a monitor and then set-up the config file: i'll let you know.
I'm puzzled by the fact that I cannot access the SD boot in any way and I was wondering if there is anything else I should try.

Is your power supply giving out enough power to the pi because if nothing is happening then it could be because of that
the LEDs on the side should tell you what you need to know
Is there a solid red light, if it is flickering, there's your problem
the green light could tell you if its the sd cards fault, see what the sequence is and say it in here or bing it, (jk use google)
Just a suggestion
Running Raspberry Pi OS Full, therefore my comments will be based on that
Using RPI-4B 4GB at 2.1GHz CPU and 700MHz GPU
don't format your sd because someone said so.
Or put your favourite cutlery into your nearest outlet (May result in death) ;)

Something fishy here...
The root partition on the SDcard is FAT32, accessible to the universe.
If your Windows, Mac and GoogleChrome (THREE different machines) cannot see it,
maybe the card is blank, or defective.

I suggest you download the latest Raspian from the Raspberry Pi website
then download Balena Etcher to use in creating Raspbian SDcards.

came into this forum: no one seems to have my problem.
No, the HDMI problems exist... you are not alone
Ah, I got a monitor also, but it has only DisplayPort.

AS has been mentioned, cheap (read: low quality) cables can be very problematic.

I have used Amazon Basics from Amazon (duh)
and have also found COBOC brand to be decent.

My main machine has DisplayPort.
My Pi's have HDMI of course

Agreed. Something is definitely not right. The FAT32 "boot" partition should be readable on just about any computing device. This indicates the card may be defective.

The Raspberry Pi Imager utility will let you easily install Raspbian, although downloading a Raspbian image and using Etcher also works.

If either program has trouble writing the image then get a new card, and verify your card reader is SDXC compatible (or get one of those as well).
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?

All,

I got my micro-HDMI to VGA cable adapter and connected the Rasp to the monitor, but no signal.

I can also see that the green light blinks once when I connect the power, but then only the red one stays on: what does that means?

my last resort now is to reset the SD card.

I'll follow the provided instructions.

Thanks!

WIth no SD card in and turning on the does the green LED flash 4 times over and over? If not the Pi is probably broken.

Ok.

Downloaded the Installer, followed the instructions and got the NOOBS in the SD card.

If I plug in the SD into the Rasp, still no output, but the Green light flashes for a bit (more then before)

The card is still not visible in Window (only the RECOVERY folder now) and I can see the config_file.txt

I set the:

hdmi_force_hotplug=1

but nothing... I'm running out of options here..

OK thanks!

ALL DONE! I'm in.

I had to reset multiple times the SD card that was probably corrupted from the beginning.
I now managed to access the TV on first try without modifying anything.

Thanks a lot and see you soon!
