Those resistors have never been populated in the first place. It's not a mistake, but a common practice to have "optional" components on the PCB, and decide if you actually want to put the components at the time of PCB assembly.
Sorry to say, but this is not the source of the problem.

---CoryThanks in advance if you can help me out.If anyone has one of these transilluminators and wouldn't mind opening it up, I could use the values of the 3 missing resistors shown in the first picture. It's really easy to open. There's 9 screws on the back. Once those are out it comes apart in two pieces and the top of the board is visible.See the images here:Hi everyone,A non-functional blue light transilluminator was donated to my lab. It's an Invitrogen Safe Imager Blue Light Transilluminator 2.0. I cracked it open and found it was missing 3 surface mount resistors. Otherwise the device seems to be in great shape.
