Halot Mage (not pro) no pattern on print screen

Set it up like normal. Ran a print. Nothing printed. Took vat off and ran exposure test. No pattern on print screen. Can see UV light glow, but nothing is showing up on the print screen. Print screen issue?

Same issue , I have replaced my LCD screen and UV lamps , Still only faint UV light when tested in Clean Vat Mode. Still trying to figure it out
