UV Lamp dim

[TheKellector]

Hello. I've noticed repeated print failures when the model was positioned in the upper left corner of the print area (if viewed from above). This has happened since I purchased my Saturn.  I've leveled numerous times and replaced the FEP but the problem continues.  Today I got the bright idea to test the exposure and noticed the UV lamp in that corner was noticeably dimmer than the other lamps. Could this be the issue and is there anything I can do about it other than buy another printer?  Thanks.

How many hours on the printer? It is much more likely that the LCD shutter is worn out than that the lamp is bad...
