"No Signal" 7 days

Someone, please give me a hints.
I feel little tired…
My PICADE screen shows “No Signal” on top left, and black out after few second.

I tried a lot of solution ideas from the internet, Through this week.
hdmi_force_hotplug=1? Ofcourse.
hdmi_safe=1? Ofcourse.
config_hdmi_boost? Yes, I tried to set that to 11. (Ofcourse it was in vain)
Connet to TV’s HDMI? Yes, I can see Retro Pi logo on my TV.
And I finished all required settings with TV.
Game sound is from small speaker on PICADE cabinet.
But still PICADE monitor screen shows simply black.
(From this, my HDMI cable, Raspberry Pi 3B+, PICADE X Board, Retro-Pi on micro SD are fine)
So, I’m connecting HDMI to my 60 inch TV.
60 inch TV!
Where is my tiny arcade days…

Some one, Please give me more hint about this situation.
Should I get one more screen?
or, Is there a solution I have not tried it yet…?

I want to cpmplete my PICADE. Simply…

thx

It sounds like there may be a fault with your screen driver board- sorry about that!

You should drop an email to support@pimoroni.com with your order number and request a replacement. It’s also possible they might know some debugging steps that I don’t.

Thankyou… I’ll try that.

I had that last night.

I had my pi already in use connected to my TV before I hooked it up to the console, so I knew it worked.

Then I got the “No signal” issue once I hooked it up to the picade console for the first time.

The screen was powering on but the pi when connected wasn’t booting up. Hence “No signal”.

I disconnected the mini USB that runs from the pi to the display driver board. Meaning the screen needed it’s own power source.

I plugged in another USB power supply to the display driver board.

So now the Pi and the driver board had two separate power supplies.

It booted up.

After that I installed the hat driver software from the web site. It makes the software changes, no messing with config files manually.

Rebooted.

Powered down, reseated the mini usb and went back to one power cable on the pi. It works now.

Could you paste the contents of your /boot/config.txt, please?
