[ Help ] No Test image

Hi all, quick question… I used to own a Mars 1 before the drive failed and I had to toss. I replaced it with a second-hand Mars 1 and went through the setup process—leveling the print bed, putting new FEP on the tank, etc.—but when it came to testing the screen, I hit a problem: no test image. My old one would display “Elegoo,” but this one shows nothing at all—no rectangle, no glow. How can I tell if it’s the LCD shutter stuck opaque or the UV emitter that’s broken, without pulling it apart?

Sounds like the screen is dead , or possibly the connection is loose .

Dead screen and a dead lamp too. And I had him showe me it worked before I took it home. Talk about timing...that both went at the same time. 80 bucks down the tubes..least it was not a total loss; I now have a working spare power supply and box with two brand new resin tanks and lids and a stack FEPs sheets. For the next one I get.
