Screen will not turn on / Black Screen

Feedback

Hello, I bought my Pimax 4K VR last December and it had worked great just until a few months ago (I just decided to start fixing it now).

Basically the screen will not turn on.

I have installed many versions of PiPlay, flashed the correct firmware to the device (100 serial #), tried multiple computers and it still does not work.

The device IS detected, sound DOES work, and tracking also WORKS. It’s just the display is black.

I have not dropped the device or misused it.

MY GUESSES TO A SOLUTION:

  • Could the infrared sensor be broken / damaged?
  • Could the internal wiring have become lose on the display causing no connection?

Does the blue LED lights on?
Perhaps you need to hard reset your HMD

Let’s check the resolution in pimax_setting, try 1980x1080.

Yes, blue LED light is on at the top.

6

Yes, Resolution is 1920x1080

So it seems, there is a hardware problem.
You can try to open the HMD by using a mini screw driver (cross) and open the screws on the sides who are coveres with closure stoppers. Or you go to a specialist to ask for.

I might have to open it myself, if the official Pimax Support doesn’t help much then it looks like I’ll do that. I’ll let you know my findings as soon as I can.

RIP Pimax, just blinking Red and Green. Tried to flash a hacked firmware too and still nothing.

Let me see if I can help. I assume you flashed my hacked FW ? Did it flash succesfully ?

The flashing Red&Green makes me think the flash failed and that you’re not on my hacked FW just yet.

I downloaded the firmware flasher tool as well and used that, it says it was successful but still nothing :frowning:

12

If you restart the flashter tool, what FW version does it say you’re on ?

I often have that black screen issue. Than I always remove the USB cable, plug it back in, restart SteamVR and most times it works then.

Hi, usually we do not recommend users to disassemble the headsets, which may break the warranty.
