Hi Hazemghamry ,
Can you please check, if your StereoPi boots without any external equipment connected?
I.e. disconnect everything, just leave Compute Module, micro SD, power and HDMI, and try to turn it on.

If one red light, near the camera connector, is blinking, it means system tries to boot. If it is blinking on your StereoPi?
If not - please check Compute Module is installed correctly (like described at the beginning of this video: https://www.youtube.com/watch?v=4KVbzQP ... e=youtu.be)
Also please check your micro SD is Ok. You can try to record a fresh SLP image. You can download it from the "Downloads" section in our Wiki (right bottom part), here: https://wiki.stereopi.com
Please notice, that "recording" means not just pasting a file to the micro SD, but recording it using a special software, like Win32DiskImager or Balena Etcher. All steps for the micro SD card preparation with the SLP Raspbian image are described here in our Wiki.

We need to localize this problem.
Can you please test the system as I described in my previous post here?
Could you please also share a photo of your setup.

It broke a couple of months ago and it was working anf I didn't use it ever since I used VNC from my pc
I assume that the problem is in the compute module because I tried different sd cards and it didn't work so the problem is not in the software and the power is working fine, what do you think?

I had a similar problem, my hdmi connector came a little loose but all the solder connections are still secure, just the two large side pads. The power supply and sd card is perfect but I get no hdmi output and no ethernet lights, I can't tell whether the system boots, all three lights are solid red, no flashing. Don't know what to do?

Dear Hazemghamry and Delgoodie,
I can suggest that unsoldered HDMI leads to some short circuits and other bad results. Let me suggest a replacement for you both. I've just sent you emails to the addresses you used for the registration on this forum. Please answer :-)

I got the same problem about the HDMI port was not working. The three lights were always on after turning on the switch.

Worasit Sangjan, if your HDMI connector sits fine on the board? Or you can see some parts are not soldered correctly (detached)?

The HDMI is working well (I tested it with another StereoPi board). I did not see the issues about soldering.

Actually it seems like I am facing similar issue. My stereopi suddenly stopped working today and doesn't seem like the board is attempting to boot (all three red leds stay static no, no blinking). I don't see any soldering issues or components coming out and I did make sure that the compute module is inserted properly.
The SD card seems to be working fine since I booted using the same sdcard on another rasberrypi (I am using the raspbian image and not the SLP image). Attached is the picture of my board.

Sorry for my late reply!
Aditya-sf , I see T-connector on your photo and hi-current wires from it. I hope they come from BEC, but not from the LiPo battery. Can you please confirm you are using 5V for powering the StereoPi?
I also mentioned you are using the GPIO powering method, but this should not be an issue. Can you please confirm, that both JST connector powering and micro USB powering methods give you the same result?

Yes the power is through BEC (5V output) and not from LiPo directly. I tried other methods of powering it but the same result.

Aditya-sf and Worasit Sangjan, let me suggest you a replacement. I will send you the StereoPi board + CM3+ Lite. Please check your email (I use the address you used to register on this forum).
I will be pleased if after receiving the replacement you can do two tests:
1. Test the replacement setup (new StereoPi board + new CM3+ Lite)
2. Test new StereoPi board + old CM3+ Lite.
I'd like to understand, either your StereoPi is not working properly, or CM3+ Lite is broken.
