DP48 No Screen, buttons responsive?

Post by JohnSmith2 »

Hi team,

Another DP48 issue/question :-)

Setup:
M32C (4.06) -> {AES} -> HUB4 -> {AES} -> DP48 (2.2)

I have 4 units. All working well, except one just starting displaying odd behavior, making it unusable. Upon boot, the screen shows nothing - no midas booting screen, and no group names etc. The buttons are responsive, however they seem to be in a different "mode" than the other ones. It's almost as if it's "locked out" somehow? It was working until very recently (though was accidentally left on all weekend...)

Swapping cables and ports on the HUB4 isolates the issue to this specific DP48.

Any advice appreciated!

Edit to add some additional detail on how the buttons are behaving in case it sparks some ideas:
on my "working" DP48, when I press both SD-Rec and Setup, both those buttons turn red and I get the preset screen.
on my "not working" DP48, when i do the same, both buttons alternate between both white, and both off.

The "not working" DP48 has no screen, even when i try to put it into firmware update mode (hold setup while powering on)

That seems to be a hardware failure.
